Mini cleat. Outlets can be fitted with sewn in pull

cord, which can be keeled into the cleat. Available

for round- and half round outlets (see example

below)

Internal steel rings, fitted inside outlet with velcro

for ease of maintenance. Mat.: S.S. AISI 314 (for

systems with low- or fluctuating pressure). Assures

that outlets are fully stretched

Metu frame, for connection to rectangular steel

ductwork, also compatible with LS-system.

(Transition from rectangular into round also textile)

D-Luxe bottom (for half round outlets). Wingrail installation

is finished of with an aluminium end piece that snaps into the

rail without the use of tools. At the end of the outlet, two mini

cleats are fitted in the rail openings, into which the sewn-in pull

cord can be locked in position. This ensures a beautiful and fully

extended outlet with wrinkle free appearance.

Special suspension feeder tool for outlets using a

combination of either Flexrail and Fasttrack or

Wingrail and Fasttrack. (Reduces the number of

man hours needed to mount an outlet)

Outlets can be had with sewn in anti

static band (sewn-in carbon fibre

band) for eliminating build-up of

static electricity (primarily used in EX-

areas and the electronics industry)

Sizing of inject outlets

4.1.9

The exit velocity through the orifices has great

influence on the degree of mixing with the room air

achieved, and the throw gained. The pattern of the

holes is standardized, so that a given static pressure

always gives the same exit velocity (However, as

always options are possible, please call us if you

have a application calling for a non-standard

selection).

Inlet surface

EURO AIR has determined the standard diameter

and the pattern of the holes. A change in the orifice

surface can only be made by changing the number

of hole rows (as a rule, but options are possible, see

above). Euro Air uses the number of hole rows as a

parameter for the orifice surface.

Air volume

Normally the air volume given is for the entire

length of the outlet. However, the possibility also

exists that the Inject outlet is used for part air

transfer, and part introduction of inlet air. In this

case, the outlet diameter must be sized for the total

airflow, whilst the number of hole rows is found

using only the inject part of the air flow.

Air inlet direction

The orientation of the orifices can be givven as aces can be g

vector, or alternatively as a time (Oclock)). In ourime (Ocloc

standard 12:00 equals 0 / 360 degrees, 15:000 equalsdegrees, 1

90 degrees, 18:00 equals 180 degrees, etcc.0 degrees, e

Calculation Inject outlets

MHM

EURO AIR recommend to work with a static

pressure inside bracket 70 to 120 Pa and to

keep inlet velocities below 8 m/s. If these

values are exceeded, please contact your local

EURO AIR office, who will help you by finding

the correct solution.

Half round inject outlets

The half round Inject outlets differs only by

its shape from the round Inject outlet, so only

when sizing diameter, please turn to charts

10,11 or 12 instead of 3,4 or 5.

Euro Air Special service

As for the slot diffuser outlets, we have the

experience and software needed to simulate

air velocities at any given distance from the

outlet. Please do not hesitate to call us, we will

be only too happy to provide this service.

Sizing of nozzle outlets

4.1.12

Basically we are here dealing with a combination of

a diffuse half round outlet (upper part), and slot

diffuser- or nozzle type half round outlet (lower

part).

The diameter must be selected using the projected

airflow and in conjunction with charts 3,4 or 5

depending on air flow.

Then size each part of the outlet (upper and lower)

as you would for the stock item, only paying very

much attention to reaching identical pressures for

the two halves. This is often easier said then ddone er said then

when sizing manually. We will often end up often end u

combining several permeabilties in order to reacch order to re

the correct air flow for each part, at t the same

pressure. If this is neglected, the outlet will givee utlet will gi

varying air flows, depending on membrane uninit membrane u

running in heating- or cooling mode. This cann of ode. This c

course not be accepted, and for the same reaason the same r

Euro Air prefers to size these outlets, to the e outlets, to th

specification needed from the customer. Thherefore, e customer.

the above is only intended to give you a glimpse of glimpse of o give you a

1. Installing round outlets on single- or double

horizontal cable

- Suspend main horizontal cable at desired height ,

using turnbuckle(s) and wire locknuts.

- Attach 1 pcs. strap-up to overhead anchor point

for every 5 meters of outlet, and fasten strap-up to

main wire to maintain a straight and level run.

- Mount the outlet to the cable using the sewn-in

clips fitted to the outlet

- Fix outlet to steel duct / Fan opening using steel-

or textile clamp

- Stretch the outlet to fully extended position, and

fix the last clip to the main wire using wire lock

nut.

- Outlets with diameters 800 or larger must be

mounted on two parallel main wires. If this is

not adhered to, Euro Air A/S will not warrant

claims involving clips/wire/strap-ups or any other

products involved mounting the outlets. We

normally advise customers to use double cable

suspension for diameters 630 and upwards, due

to aesthetics and to minimize the drop that will

occur if a single row suspended outlet is deflated.

1. Montering af rund posekanal, med clips p wire

- Strap-up fastgres til loft, der anvendes 1 stk.

strap-up per 5 meter posekanal

- Hovedwire monteres og udspndes ved hjlp

af wirestrammer, og fikseres efterflgende med

wirelse

- Posekanal monteres p hovedwiren ved at klemme

clipsene fast p wiren

- Strk posen helt ud, og monter derefter n

wirels umiddelbart fr den sidste clips p posen

(typisk hvor poser er afsluttet i bund). Dette

forhindrer posen i at bevge sig vsentligt i

lngderetningen som flge af f.eks. on/off drift

- Posekanal monteres p stlkanal / ventilator vha.

spndebnd

- Strre diametre (diameter > 800) skal monteres

p 2 parallelle hovedwirer. Er dette ikke tilfldet

trder Euro Airs garantiordning ud af kraft,

sfremt der skulle opst problemer med clips/wire/

strap-ups, eller andre komponenter involveret i

montagen af posekanalen. Normalt anbefales dog

fra vor side dobbelt wire montage ved -ml 630

og strre, af hensyn til nedhng samt stetik.

Washing instructionsCleaning of polyester and Trevira CSWash 2-4 times at max 40C with washing powder in accordance to instructions by manufacturer.If outlets are heavily soiled, they should be rinsed between washes.If the outlets are to be disinfected, add min. 200 mg/L of active chlorine to the final rinse water (N.B. colored socks can loose some of their color when disinfected)Rinse outlets in clean cold water.Socks can be spin dried, the exception being outlets with internal rings. Here the rings must removed prior to drying.

Chemical cleaning of polyester and Trevira CS Chemical cleaning of outlets should only be attempted in cases where the outlets are slightly dirty.To achieve some degree of disinfection, it is recommend to use chemical cleaning with perchlorethylen.

Washing or chemical cleaning, clean room materialsWashing or chemical cleaning of clean room materials is not recommend under normal circumstances, but is possible following the procedures given for Polyester and Trevira CS material. If the fabric turns slightly grey during operation, the pre-filtration should be examined and possibly exchanged for a filter better suited. During the washing procedure, particles can be picked up by the fabric and later blown into the room. If the clean room socks are being washed there is no further guarantee for the function of the socks from EURO AIR, with regards to particle count.

Cleaning of Inject outletsEURO AIR Inject outlets do not require cleaning from a flow technical point of view, however aesthetics or hygiene conditions may necessitate the cleaning of the outlets.EURO AIR Inject systems can be cleaned manually on the outside and on the inside. For this purpose a thin water/soap dilution and a brush or a sponge should be used (standard grade washing detergent can be used).After the cleaning the Inject Socks should be rinsed with clean water.If the Inject Sock is very dirty the inside of the sock should be turned out and swept or vacuumed. Use of Hydrocarbon based solvents can cause damage. Under no circumstances use solvents containing Chlorate, this will deteriorate the PVC coating, causing the material to turn brittle, eventually cracking can occur.

Cleaning of M0 Outlets (Glass fibre weave)These outlets must only be cleaned by means of a damp cloth. A standard commercial grade detergent can be used in a watery solution for this purpose. Outlets must be allowed to drip dry.

VaskeanvisningVask af polyester og Trevira CSVask 2-4 gange ved max. 40C, tilst vaskepulver i dosering svarende til fabrikantens anvisning. Sfremt posekanalerne er meget snavsede br disse skylles mellem hver vask. Efter endt vask efterskylles i rent koldt vand. Sfremt poserne nskes desinficeret kan dette opns ved at tilstte min. 200 mg/L aktivt klor til sidste hold skyllevand (vr opmrksom p at farvede kanaler ved denne desinficering kan blive let blegede). Sfremt der desinficeres efterskylles igen med rent koldt vand. Kanaler med interne ringe kan centrifugeres, blot skal ringene demonteres fr dette kan foretages.

Kemisk rens af polyester og Trevira CSKemisk rens af tekstil kanaler br kun anvendes i tilflde hvor disse har en lav- til middel tilsmudsningsgrad. Ved kemisk rens br der anvendes perklorthylen, og kanalerne br udluftes.

Vask eller kemisk rens af renrumsmaterialerVask eller kemisk rens af renrums materialer anbefales ikke under normale omstndigheder, men er dog muligt som nvnt ovenfor for polyester og Trevira CS materiale. Hvis kanalen har en tendens til at blive grlig i farven br forfiltret efterses, og eventuelt udskiftes med filter af hjere filterklasse. Under rense- eller vaskeprocessen kan posematerialet blive forurenet med stvpartikler og lignede, hvorfor Euro Air A/S fralgger sig ansvaret for rensrumsklassen efter en eventuel vask.

Rengring af injekt materialeKan ikke maskinvaskes. Euro Air injekt kanaler krver ikke vask eller rens ud fra et luftteknisk synspunkt, idet dette materiale er ikke-permeabelt, det vil sige, materialet stopper ikke til selv om der stvpartikler tilstede i indblsningsluften. Poserne kan rengres manuelt p yder- og inderside med en tynd sbeoplsning vha. svamp og brste. Efter rengring vaskes poserne over med rent vand. Der m under ingen omstndigheder bruges klorholdige rengringsprodukter, idet kloren kan nedbryde PVC-belgningen.

Rengring af glasfibervvKan ikke maskinvaskes. Kan rengres med fnugfri klud pfrt tynd oplsning af sbevand. Skylles efterflgende med rent vand og dryp trrer.

1. Installing round outlets with Fasttrack onto

ceiling mounted Wingrail

- Attach Wingrail to ceiling using screws for every

300-1000mm depending on type of ceiling and size

of outlet. Note: the wing on the rail has a groove

for lining up when drilling the holes needed in the

rail.

- Sections of Wingrail is joined by sliding the

Wingrail connector into the side groove of the

rail, and then tightening the allen screws. When

tightening the allen screws, the 2 sections of rail

will self-align.

- The Fasttrack cord fitted to the outlet is slid into

the rail opening, and can now be pushed/pulled

into the rail. If you have ordered our special

Fasttrack feeder tool, this must be fitted into the

side groove prior to sliding the outlet into the rail.

Using the special feeder tool the outlet can be pull

onto the rail very easily with a minimum use of

force.

- The outlet is fixed to the steel duct or fan using

clamp.

- If Luxe bottom was ordered you will also have

received a small cleat (stamped Mini cleat) per

outlet. This cleat is mounted directly onto the

rail, at the end of the rail where the bottom of

the outlet will be located. The cleat is fitted using

the included special flat nuts and bolts. When the

outlets are ordered with the Luxe type bottom

the outlets have a pull cord attached at the

bottom end. This cord is pulled tight and fixed into

the cleat. Following this, the cord can be shortened

as needed.

1. Montering af rund posekanal med Fasttrack, i

loftsmonteret Wingrail skinne

- Skinne fastgres til loft med skruer per

300-1000mm, afhngigt af loftstype samt

kanaldimension. Bemrk at skinnen har et

spor i montage fligen, for nemmere at styre

boremaskinen, samt sikre korrekt hul placering.

- Hvor skinner skal samles indskydes skinnesamler i

samlersporet, og fastspndes. Herved sikres at de

enkelte skinnestykker liner korrekt op.

- Posekanalens Fasttrack fres ind i Wingrail

skinnens montage spor, og kan herefter trkkes/

skubbes ind i skinnen. Sfremt der er bestilt vort

specielle montagevrktj for Wingrail skydes

denne frst ind i samlersporet p skinnen. Herefter

kan posen ganske ubesvret trkkes p skinnen,

med et minimum af trkpvirkning ndvendig.

- Posekanalen fastgres p stlkanalen/ventilator

ved hjlp af spndebnd.

- Hvis der er bestilt Luxe-bund til posen,

medflger ligeledes et stk. mini-cleat

(skdeklemme) per pose. Denne monteres direkte

p skinnen (der medflger special mtrikker

samt skruer til dette forml), i den ende hvor

posekanalens bund sidder. Nr der er bestilt Luxe-

bund er posen udstyret med en kraftig isyet snor

ved bunden. Denne snor bruges til at strkke

posen helt ud, hvorefter snor kan kiles fast i

skdeklemmen. Snoren kan slutteligt afkortes

efter behov.

1. Installing round outlets with Gliders onto ceiling

mounted Wingrail

- Attach Wingrail to ceiling using screws for every

300-1000mm depending on type of ceiling and size

of outlet. Note: the wing on the rail has a groove

for lining up when drilling the holes needed in the

rail.

- Sections of Wingrail are join by sliding the

Wingrail connector into the side groove of the

rail, and then tightening the allen nuts. When

tightening the allen nuts, the two sections of rail

will line up nicely.

- The Gliders fitted to the outlet is fed into the rail

opening, and the outlet can now be pulled onto

the length of rail.

- The outlet is fixed to the steel duct or fan using

clamp.

- If Luxe bottom was ordered you will also have

received a small cleat (stamped Mini cleat) per

outlet. This cleat is mounted directly onto the

rail, at the end of the rail where the bottom of

the outlet will be located. The cleat is fitted using

the included special flat nuts and bolts. When the

outlets are ordered with the Luxe type bottom

the outlets have a pull cord attached at the

bottom end. This cord is pulled tight and fixed into

the cleat. Following this, the cord can be shortened

as needed.

1. Montering af rund posekanal med Glidere, i

loftsmonteret Wingrail skinne

- Skinne fastgres til loft med skruer per

300-1000mm, afhngigt af loftstype samt

kanaldimension. Bemrk at skinnen har et

spor i montage fligen, for nemmere at styre

boremaskinen, samt sikre korrekt hul placering.

- Hvor skinner skal samles indskydes skinnesamler i

samlersporet, og fastspndes. Herved sikres at de

enkelte skinnestykker liner korrekt op.

- Posekanalens glidere fres ind i Wingrail skinnens

montage spor, og kan herefter trkkes ud p

skinnen.

- Posekanalen fastgres p stlkanalen/ventilator

ved hjlp af spndebnd.

- Hvis der er bestilt Luxe-bund til posen,

medflger ligeledes et stk. mini-cleat

(skdeklemme) per pose. Denne monteres direkte

p skinnen (der medflger special mtrikker

samt skruer til dette forml), i den ende hvor

posekanalens bund sidder. Nr der er bestilt Luxe-

bund er posen udstyret med en kraftig isyet snor

ved bunden. Denne snor bruges til at strkke

posen helt ud, hvorefter snor kan kiles fast i

skdeklemmen. Snoren kan slutteligt afkortes

efter behov.
