Flow Ezy Air Sentry Breathers replace the standard breather cap or vent tube on a tank or reservoir. They are

easy to ins tall using one of several adapters designed for different applicat ions.

When the fluid in the system is lowered, or pressure changes occur, air is drawn in through openings under the

breather cap. First, air passes through a fine, 2 micron solid particle filter. The a ir then passes through a diffuser to

ensure maximum effect iveness within the s ilica gel cha mber.

Next, water vapor is removed as the air travels through a bed of s ilica ge l - the highes t capacity adsorbent avail-

able. After being dried, the air passes through a second 2 micron solid particle filter and enters the reservoir

CLEAN AND DRY!

Flow Ezy Air Sentry Breathers use a three-stage filtration des ign to ensure optimum protection by remov ing wa-

ter vapor and solid contaminants before they enter the fluid system.

Flow Ezy Air Sentry Breathers are patented in the United States .

Key Benefits Protects Expens ive Equipment

Increases Operation Efficiency

Reduces Maintenance Costs

Operational Features

Bi-Directional Air Flow - Air entering is cleaned and dried. Expelled air partially regenerates the silica gel and

"back flushes" the particulate filter to prolong the life of the breather.

Durable Construction - Air Sentry is manufactured from rugged ABS plastic and impact-modified Plexig las.

Water Vapor Adsorbent - The Silica Gel used in Air Sentry breathers is chemically inert, non-corrosive, and

conforms to all regulated toxicity standards in the U.S. and other countries. Microscopic pores allow the silica gelto adsorb up to 40% of its own weight.

Color Indicator - When maximum adsorption is reached, the silica gel turns from gold to dark green to indicate

that replacement of the b reather is required.

Activated Carbon - As air is expelled from the tank, it passes through activated carbon which removes oil vapors,

fumes and odors.

Safety Sealed - Seals keep moisture from entering the units until they are placed in service. They are easily re-

moved without tools or sharp instruments .

In any reservoir containing flu ids or semi-solids, air is breathed in and out as

the fluid level changes or as thermal expansion and contraction occurs.

Fluid contamination is the primary cause of component wear and lubricantfailure in industrial equipment.

Flow Ezy Air Sentry replaces the standard breather cap or vent tube on a

tank or reservoir. They are easy to install using one of several adapters de-

signed for different applications.

When the fluid in the system is lowered, or pressure changes occur, air is drawn in through openings under the

Test:

Two clean containers were filled with hydraulic fluid and fitted with Flow Ezy Air SentryBreathers. Two more containers were set up with the same configurations, except using stan-

dard breather caps with screen filters. The fluid was pumped back and forth between the con-tainers, causing air to be breathed in and out of each drum. Both units were subjected to thesame atmosphere and were filled with the same batch of hydraulic oil. The atmosphere con-

tained low levels of moisture and high levels of particulate. Both systems were run for sixmonths at the same pumping rate. The test was controlled and supervised entirely by laboratory

personnel.

Results:

The count of solid particles, 5 micron or larger, in the new fluid in both containers at the begin-

ning of the test was approximately 500 parts per milliliter. At the end of the six month test, thecount in the containers protected by Flow Ezy Air Sentry Breathers was 786. The count inthe containers fitted with standard breather caps was 1,854 particles per milliliter, an increase of

265%; a significant difference in the entrance of abrasive contaminants, which would result inlonger fluid life and less wear on the components serviced by the fluid.

The water content in the containers fitted with standard breather caps went down during the sixmonths test from 2.14 parts per million to 1.44 parts per million, an improvement of 33%. The

moisture content in the containers protected by the Flow Ezy Air Sentry Breathers droppedfrom 3.73 parts per million to 0.79, an improvement of 79%. This dramatically lower watercontent in fluid systems helps prevent fluid breakdown and oxidation, reduced lubricating film

thickness, corrosion, accelerated metal fatigue, or loss of dielectric strength in insulating fluids.

Z SERIES MINI CONTAMINATION CONTROL BREATHERS

PROTECTS GEARBOXES & SMALL

HYDRAULIC RESERVOIRS

Most gearboxes and small hydraulic reservoirs have asimple breather/filler cap that allows air to be breathed

in and out as fluid levels change or temperatures in-crease or decrease.

Standard breather caps do not stop water vapor and

other harmful contaminants from entering the system .

Air Sentry does!

Air in industrial environments contain abrasive solid

particles and humidity. As the system temperature

changes, the humid air forms condensation inside thegearbox or reservoir. This moisture decreases fluid and

lubricant effectiveness, and reduces their service life.

Particulate contamination, mixed with the systemsfluid or lubricant, acts as an abrasive compound that

greatly increases fluid component wear resulting inequipment failures and higher maintenance cost.

Moisture in a gearbox can cause it to rust from within.Rust flakes in the lubricant, producing additional abra-

sive material, premature wear and failures.

Small hydraulic pumps are sensitive to these problems.Hydraulic valves, seals, and other components, require

contamination free fluid to funct ion at peak effective-ness and accuracy. These components are increasingly

expensive to rebuild or replace.

Flow Ezy Air Sentry stops oil contaminationand protects your expensive equipment.

Flow Ezy Air Sentry Mini Contamination Control

Breathers are designed for applications when space is

limited. They can replace all standard breather caps.They also prevent dirt and water vapor from entering the

gearbox or hydraulic system.

BENEFITS

Minimize rust and corrosion

Reduce component wear

Reduce maintenance costs

Prolong f luid life

Reduce oil oxidation

Water vapor is removed as the air travels through a bed

of silica gel, the highest capacity absorbent available.

After being dried, the air passes through a 2 micron solid

particle filter and enters the gearbox or reservoir

CLEAN AND DRY!

Flow Ezy Air Sentry is gold when active and darkgreen when it must be replaced.

A threaded mounting hole (1/2 npt) allows easy instal-

lation using a wide variety of standard connectors. All

models are rated at 10 cfm.

X SERIES TANK BREATHER WITH TWO CHECK VALVES

In certain extreme operating environments such as a paper mill or a steam cleaning room, the humidity level far

exceeds normal industrial environments . In these situations, lubricants and other fluids stored in tanks and reser-

voirs need the protection of a desiccant breather even more. However, s mall temperature variations draw in the

humid air and unnecessarily reduce the life of the breather. The Flow Ezy Air Sentry X-Series breathers incorpo-

rate two check valves, one to control airflow into the protected reservoir and one to control airflow out. This pro-

longs the life of the des iccant by allowing the air to flow through the breather only when

needed to protect the integrity of the tank.

Unlike a membrane system, which does not allow internally generated gases and con-

taminants to exit the system, the X-Series offers all of the advantages of breathing air in

and out of the tank while removing water vapor and solid particles before they contami-

nate the fluid.

The rugged design includes a reusable top cap which allows the economic replacement of

the desiccant cartridge.

The X-Series breathers contain longer lasting desiccant formulated specifically for maxi-

mum efficiency at humidity levels of 80% and higher.

The mounting methods for the these units are shown below. As in the standard units, the

X-Series units require the s ame mounting methods.

BY-PASS ADAPTER

The Model A-110 Bypass Adapter is des igned for applications where

there is very heavy oil mist being expelled from the tank. When air is

breathed into the tank, it passes through the Flow Ezy Air Sentry

and is cleaned and dried. When the air is breathed out of the tank it

enters the adapter and is e xpe lled to the outs ide without passing back

through the breather. This protects the breather from oil contamina-

tion.

R SERIES REMOVABLE CONTAMINATION CONTROL BREATHERS

Flow Ezy Air Sentry R-Series Breathers are designed for applica-

tions where gearboxes and reservoirs are subjected to continuous vi-

bration equipment such as railroad maintenance equipment, off-road

vehicles , mining equipment, and others.

Flow Ezy A ir Sentry Breathers are gold when active and turn dark green

when fully saturated with water.

The units are easily attached to the equipment by rugged steel pipe

threads. The metal rein forced base of the unit remains o n the gearbox or

reservoir, and a rep lacement cartridge is easily threaded into the bas e.

Most gearboxes and hydraulic reservoirs have a sim-

ple breather-filler cap that allows air to be breathed

in and out as fluid levels change or temperatures in-

crease or decrease.

Standard breather caps do not stop water vapor and

other harmful airborne contaminants from entering

the system. Air Sentry does!

Air in indus trial environments contain abrasive solid

particles and water vapor. As the system temperature

changes, the humid air forms condensation inside the

gearbox or reservoir. This moisture decreases fluid

and lubricant effectiveness and reduces their service

life.

Particle contamination acts as an abrasive compound

that increases component wear resulting in equip-

ment fa ilures and higher maintenance cos t.

Moisture in the gearbox can result in acid erosion

and rust, two of the worst causes of premature wear

and failure.

Hydraulic systems are very susceptible to these prob-

lems. Valves, seals, and other expens ive parts re-

place ment costs.

R-Series Breathers are attached to the reservoir, gear-

box, o r tank by a 1 male pipe thread (Models R-100, R-

101, and R-102), and by a 2 male thread (Model R-

123).

Solid particles are removed from the air entering the

gearbox or reservoir as air passes through a 2 micron

filter in the Air Sentry. Water vapor is then removed

as the air travels through a bed of silica gel, the highest

capacity absorbent available. Air enters the equipment

M SERIES HEAVY DUTY INDUSTRIAL STEEL

DESICCANT TANK BREATHERS

Flow Ezy Air Sentry Steel Breathers are manufactured of heavy duty industrial materials and are designed to

meet the requirements of the most severe environments. They replace the standard breather cap or vent tube on

tanks, reservoirs, or gear boxes. Pipe threads on the bottom standpipe make the

units easy to install.

When the fluid in the system is lowered, or pressure changes occur, air is drawn in

through the opening between the protective weather hood and the base. First, the

air pas ses through a fine 2 micron polyester solid particle filter. Next, water vapor

is removed as the air travels through a bag of silica gel the highest capacity ab-

sorbent available. Air then enters the system CLEAN AND DRY!

Flow Ezy Air Sentry Steel Breathers are easily rechargeable when the unit has

absorbed the maximum amount of water vapor. The bag f ilter containing silica gel

is replaced by removing a wing nu t, a washer, and the protective weather hood.

Mobile Equipment Applications - Flow Ezy Air Sentry Steel Breathers include

low profile models des igned specifically for off-road vehicle use and other applica-

tions with limited vertical clearance.

Durable Construction - Flow Ezy A ir Sentry Steel Breathers are manufactured of powder coated, durable,

heavy gauge steel. They a re designed to withstand rough treatment, corrosive environ ments, and ext reme tempera-

ture applications.

Polyester Fine Particle Fil ter - These filters incorporate a very large surface area for maximum dust removal

efficiency. They are re inforced with epoxy coated steel wire and may be washed with lukewarm water and mild

detergent for reuse.

Splash Sentry - A proprietary design feature in all Flow Ezy Air Sentry Steel Breather models prevents fluid

in a tank or reservoir fro m entering the breather when splashed around in a mobile equipment application. It also

blocks fluids which are expelled by e xcess pressure and foaming in a reservoir.

GNS SERIES GAS NEUTRALIZATION BREATHERS

Flow Ezy Air Sentry GNS (Gas Neutralization System) was designed in coopera-tion with a major international a irline / air cargo company for use on ground support

equipment. When batteries are charged, gas is produced that contains hydrogen and

su lfuric acid. Many health and safety regulations require that charging be performed

in a specially designated area where personnel and electrical equipment or open

flames are a safe distance away. A lternatively, an expens ive investment in gas ex-haust systems is required.

The Flow Ezy Air Sentry GNS Breather provides an economical and simple solu-

tion to the problem. The GNS Breathers are easy to install by means of valves at-

tached to the battery vents and plastic tubing which conducts the exhaust gases to the

GNS mounting point, located either on or off the equip ment. This flexibility allows

the charging to take place at the work site or in an enclosed work area where staff is

present.

Applications include all mobile and stationary electric battery-powered equipment, forklifts, marine vehicles, and

baggage haulers.

The GNS utilizes a three-stage filt ration system. As the gas mixture produced during charging moves through theGNS Breather, it first passes through a bed of silica gel that removes the water vapor in which the su lfuric acid gas

is suspended. This drying maximizes the life of the s econd stage and improves its chemical absorption capacity.

In the first s tage, the hydrogen content of the gas is also s lightly reduced. Second, the gas passes through a bed of

activated carbon which neutralizes the sulfuric acid gas. Third, the gas exits the GNS Breather through a co mpos-

ite metallic f ilter/diffuser, which prevents open flames and electrical sparks fro m entering the GNS unit or the bat-

tery system, thus reducing the potential for exp losion.

The mounting methods for the GNS units are shown below. As in the standard and activated carbon units, the

GNS series requires the same mounting methods .

D SERIES ACTIVATED CARBON TANK BREATHERS

Many tanks and reservoirs contain fluids that discharge undesirable gases and odors.

Flow Ezy Air Sentry desiccant breathers are produced which contain Activated Car-

bon . This includes the Dispos able Breathers, Mini-Breathers, and our R-Series

Breathers. Activated Carbon is used extens ively in indus trial, commercial, and

HVAC applications to eliminate many harmful, corrosive, or objectionable gases and

odors by chemical absorption. A list of the fluids that produce gases neutralized byActivated Carbon is shown on the back of this Product Information flyer.

The Activated Carbon used in Flow Ezy Air Sentry breathers is made f rom coconut

shell that has been heated to over 2,000 C under h igh pressure. This process causes

fissures on the surface of the carbon, creating a high quality, small pore activated car-

bon . It is in these fiss ures that gases and particles are trapped.

There are four models of Activated Carbon breathers, D-200, D-201, D-202, which

use the standard mounting options shown below. The D-208 has a 2 male NPT con-

nection. These breathers contain all Activated Carbon.

Three Flow Ezy Air Sentry breather models, D-301, D-302, D-308, are available which contain both Activated

Carbon and Desiccant. These units not only remove the fumes and odors expelled fro m a tank, they also protectthe fluid in the tank from water and solid partic le contamination.

These are cons idered disposable units. Units with replaceable carbon bag filters are available with la rger units for

industrial use. If you have an application which requires a larger capacity of a ir flow contact Flow Ezy.

Flow Ezy Air Sentry Activated Carbon Breathers are rated at 15 cfm airflow for models with a 1 standpipe, 50

cfm for mode ls with a 2 standpipe, and 100 cfm for models with a 3 standpipe. They use the same mounting

adapters that are available for the standard desiccant breathers.

The mount ing methods for the disposable units are shown below. As in the standard units, the Activated Carbon

units require the same ones.

A BRIEF LIST OF INDUSTRIES AND MARKETS THAT USE


INDUSTRY / MARKET REMARKS

Aluminu m extrusion forging and rolling mills These operations are almost exclusively oriented to hy-

draulic equipment.

Appliance manufacturers Stampings look for large hydraulic presses and some

gear boxesAutomotive industry This industry is intensively equipped with hydraulic ma-

chinery, gearbo xes, and robots.

Large transformer & switch gear manufacturers They use a large amount of insulating oil (transformer

oil), which can get contaminated. They often do rebuild-

ing work and need to reclaim o il.

Aerospace and high tech welding applications Most are performed in a vacuum, or other controlled

atmosphere. Reduce pu mp-down times and increase

productivity with Flow Ezy Air Sentry.

Day tanks on diesel powered generators In almost every large building, moisture contamination

is a big problem because desiccant tank breathers are

seldom used.

Paper and pulp mills There are many applications in these plants for Flow EzyAir Sentry breathers. Gearboxes, gear reducers, &

hydraulics. Powerhous e turbine lube oil, the lube oil

systems for dryers. The main lube system for the calen-

dar stack drive bearings.

Oil dri lling indust ry Hydraulics on the mobile equipment, gearboxes. In ar-

eas of the south, and long the coast, there are very humid

conditions. Mobile equipment in the field is subject to

huge amounts of dust contamination.

E.D.M. die making Electro-discharging machining is a high metal removing

process producing a lot of contaminated oil.

Food processing plants Wash down of equipment makes moisture a real problem

in hydraulic reservoirs and gearboxes.

Large machine shops Big users of petroleum cutting oil.

Food products: oils, grains , syrups Particularly important during filling and emptying opera-

tions.

Off road vehicles Filtering moisture and dirt, from air going to differen-

tials, trans miss ions, loader cylinders, etc.

Automatic screw machines These are basically high production lathes, which often

use petroleum based cutting oils.

Chemical & Petro-chemical p lants Micronic filtration of the process stream. Lube oil de-

gassing and conditioning. Turbine and seal oil.

Acid and chemical storage Moisture and dirt alters the fluid

Jet fuel storage at large airports Water or dirt contamination results in loss of entire prod-

uct.Plast ic injection molding Big user of hydraulic petroleum based equipment.

Power p lants & utilities Filtration application is on the main steam turbines, boil-

ers, feed pumps, and any peaking units. Transformer o il

treatment is another obvious application.

Steam & gas turbine manufacturers Paper mills, petrochemical plants, refineries, and even

distilleries are turbine users. Off shore oil drilling plat-

forms utilize gas turbines for their main e lectrical gener-

ating power source.

A BRIEF LIST OF INDUSTRIES AND MARKETS THAT USE


Steel rolling mill & forge plants A typical steel rolling mill has two stories of hydraulic

equipment beneath the roll stands. They periodically

contaminate this hydraulic oil with water based rolling

flu ids. Flow Ezy Air Sentry could prevent the con-

tamination of moisture that gets in through the breather

cap.

Wire manufacturers Water base, oil base, and dry lubricants are used in wire

production.

Mining companies They operate expens ive hydraulically powered equip-

ment, which a re exposed to a very nasty environment.

FREQUENTLY ASKED QUESTIONS

CAN I REPLACE OR REGENERATE THE SILICA GEL AFTER IT CHANGES COLOR?

With the exception of the Steel Breathers , you cannot replace the silica gel. The Steel Breathers have a replace-

able bag of sil ica gel. All other Flow Ezy Air Sentry Breathers are designed so you cannot remove the cap.

This is to assure that solid particles, water vapor, or silica gel beads do not accidentally enter the tank or reser-

voir. The silica ge l can be regenerated by blowing hot air through the breather (about 300 F for three or four

hours). We do not believe this is economical.

WHAT SIZE BREATHER DO I USE?

The size of the tank or reservoir does not determine the mode l of breather to use. The air flow, both IN and

OUT of the tank or reservoir determines the model to choose. Two factors create air flow. They are fluid vol-

ume changes and temperature variations . The air flow rating for each Flow Ezy Air Sentry model is s tated in

the sales literature.

CAN A BREATHER BE MOUNTED IN ANY POSITION, VERTICAL, HORIZONTAL, OR AT AN AN-

GLE?

Breathers should be mounted in the vertical pos ition, or at least no more than a 45 angle. Even though FlowEzy Air Sentry Breathers are vibrated during assembly to assure maximum filling, the silica gel settles during

shipment, creating an air pass age above it when the unit is in the horizontal position. Air, like people, takes the

path of least resistance, and with the breather in the horizontal position, the air would bypass the s ilica gel and

enter the tank undried.

HOW MUCH WATER DOES MY BREATHER HOLD?

The amount of water that a Flow Ezy Air Sentry Breather holds is up to 40% of the weight of the silica gel in

that model breather. We say up to because the percentage is dependent upon the relative hu midity the breather

is operating in. Ideal conditions (40%) occur at approximate ly 70 F. And 75-80% hu midity. If a customer is

concerned that a breathers life is too short, they need to understand that when it has turned completely dark

green it holds the same quantity of water, regardless of how long it took for it to change color. In the D-102 that

is about 2 cups of water. The D-102 is the most economical model for a customer to purchase.

MUST THE BREATHER ALWAYS BE MOUNTED ON THE TANK OR CAN IT BE REMOTELY

MOUNTED?

It is often des irable to mount the breather away from the tank for better visibility or easier access for changing

the units. You can mount the unit remotely by using tubing or pipes for the air to flow from the breather to the

tank. Be sure there are no obstructions in the line and no air leaks. Rigid piping, with a 90 elbow, can also beused to achieve a vertical breather pos ition for applications where the opening in the tank is on the side or where

there is not enough space above the tank for a breather.

FREQUENTLY ASKED QUESTIONS(continued from previous page)

HOW DO I DISPOSE OF A USED FLOW EZY AIR SE NTRY?

Always check local regulations . Having said that, be assured that Flow Ezy Air Sentry Breathers are manufac-

tured with all materials that can be disposed of as solid waste, as defined by local regulations. However, if a

breather is used on a tank that contains a regulated fluid, the breather must be disposed of in the s ame manner asrequired for the fluid.

HOW DO I KNOW WHEN THE BREATHER HAS ABSORBED ALL THE WATER IT CA N HOLD?

As the Flow Ezy Air Sentry adsorbs water the silica gel turns from gold to very dark blue/green. In fact, it looks

black to many people. Seeing a light green color throughout the gold is not a signal to replace the breather. When

all of the s ilica ge l has changed color, to very dark blue/green, the breather should be replaced. A breather that s tillhas a small amount of gold or light green color showing is just as good as when it had not s tarted to change color.

I DONT SEE ANY WATER IN MY TANK. DO I REALL Y NEED TO PAY FOR A DESSICA NT

BREATHER?

IT'S THERE, EVEN IF YOU DON'T SEE IT - AND IT'S COSTING YOU MONEY. There are three states ofwater contamination in lubricants, hydraulic fluid, insulating oil, etc. DISOLVED WATER - these molecules aredispersed one-by-one throughout the oil like Humidity; EMULSIFIED WATER - these microscopic globules of

water are suspended in the oil like fog; FREE WATER - settles to the bottom of the tank like rain. All forms of

water are generators of other contamination: rus t, sludge, acids, soot, bacteria, varnish, and ice. All of these shortenthe life of the oil or fluid and the equipment s erviced by it.

HOW LONG DOES A BREATHER LAST?

There is no set time frame that a Flow Ezy Air Sentry breather will last. The size of the breather, as well as the

environment it is in, will determine the life span of a breather. Generally speaking, a small Mini breather will nothave the same life expectancy as a larger Disposable Breather. The useful life of a breather has three variables.

They are:

Frequency of Breathing means how often does a new batch of wet air pass through the breather. Each time thishappens, water vapor is retained and the breather life is s hortened. Examples of the extremes would be a s torage

tank that has fluid drawn out once a day and a hydraulic cylinder stroking every 30 seconds.

Quantity of Silica Gel:The water holding capacity of a breather is directly proportional to the a mount of silica gel

in the breather. Silica ge l has the capability to remove up to 40% of its own weight in water. Ambient Humidity in the Work Area: Most users believe that the ambient humidity is the major factor in the life

of the breather. However, humidity works for us, as well as against us. As each load of wet air passes through thebreather, the air with more humidity brings more water vapor to adsorb, but the s ilica gel can adsorb more at the

higher humidity level. The end result is a small decrease in the life of the breather at higher work area humidity

levels, but this is not as s ignificant as the other two life factors. Most breathers in indus trial applications will last 3to 6 months , if s ized properly. The first breather put on a tank or reservoir that has been in operation for a period oftime will usually have a shorter life than subsequent breathers because it is having to dry air leaving the reservoir

as well as coming in. Our customers have used Flow Ezy Air Sentry breathers in nearly every climate poss ible.Some breathers will last 2 months on a fluid storage tank, some will last over a year. When the silica gel changes

from gold to green, it is time to replace the breather.

CAN I USE MY FLOW EZY AIR SENTRY BREATHER OUTDOORS IN COLD OR HOT CONDITIONS?

Yes, Flow Ezy Air Sentry Breathers are designed for use in temperatures ranging from 20 F to 200 F.

CAN I USE MY FLOW EZY AIR SENTRY BREATHER ON MOBILE EQUIPMENT? ITS A PRETT Y

ROUGH ENVIRONMENT!

FLOW EZY AIR SENTRY BREATHERS ARE DESIGNED FOR RUGGED ENVIRONMENTS. Two groupsof Flow Ezy A ir Sentry products are designed for these applications. The "R-Series" breathers was designed incooperation with a major U.S. railroad for applications with severe vibration. There is a metal reinforcing plate in

the bottom cap and the connection to the reservoir is made with a steel pipe nipple. The Steel Breathers are de-

signed for applications where the un its may be used as a step to enter a cab or hit by flying objects or other equip-ment. They are designed with a 16 gage steel body.
