Why do we compress air? Compression is undertaken for a variety of reasons. Many processes can only be carried out by compressed gases. Some of these include:
� Transmission of power for pneumatic tools.
� Shot blasting
� Paint Spraying
� Transporting materials
� Conveying
� Air separation, for industrial gases (oxygen, nitrogen).
� Amusement parks
� snow making
� Glass plants
� Blowing
� Etching
� Molding, etc.
Basic Compressor Operation There are various ways to compress air. One of the simplest is by means of a piston in a cylinder. As the piston moves forward in the cylinder it compresses the air into a smaller space, thus raising its pressure. We are all familiar with the bicycle pump, which is typical of this principle.
A reciprocating air compressor utilises the same pumping principle. Air is drawn into a cylinder and compressed by a piston, which is driven by a connecting rod and crankshaft. An air compressor is very similar to the engine in an automobile.
Air enters the compressor through a combination filter and muffler that cleans the air and silences the noise. The clean air passes into the cylinder through an inlet valve, which is opened automatically by differential air pressure. The air is then compressed by the piston and forced through a discharge valve into a storage tank.

Compressor Fundamentals
Types of Compressors
Types of Compressors There are two general groups of air compressors, positive displacement and continuous flow. Positive Displacement compressors are either Reciprocating or Rotary.
Positive Displacement
These are units in which successive volumes of air are confined within a closed space and elevated to a higher pressure.
Reciprocating
The compressing and displacing element in these units is a piston having a reciprocating motion within a cylinder.
Rotary Compressing and displacement is effected by the positive action of rotating elements
Sliding Vane
Axial vanes slide radially in a rotor eccentrically mounted in a cylindrical casing. Air trapped between vanes is compressed and displaced.
Liquid Piston
Water or other liquid is used as the piston to compress and displace the air.
Straight Lobe
Two straight mating lobed impellers trap air and carry it from intake to discharge. This is no internal compression.
Helical Lobe
Two intermeshing rotors, each with a helical form, compress and displace the air.
Continuous Flow
Ejector
Devices that use a high velocity gas or steam jet to entrain the inflowing air, then convert the velocity of the mixture to pressure in a diffuser.
Dynamic
These are machines in which the rapidly rotating element accelerates the air as it passes through the element, converting the velocity head into pressure, partially in the rotating element and partially in stationary diffusers or blades.
Centrifugal
One or more rotating impellers, usually shrouded on the sides, accelerate the air. Main air flow is radial.
Axial Flow
Air acceleration is obtained by the action of the bladed rotor shrouded on the blade ends. Main air flow is axial.
Mixed Flow
An impeller form combining some characteristics of both the centrifugal and axial types.
Compressor Fundamentals
A brief history of compressed air 10,000 The first use of compressed air was when ancient man blew on embers to start BC a fire. Thus the first “compressor” was human lungs (capacity 100 1/min,
pressure 0.02-0.08 bar(g)).
The work capability of compressed air was well understood by primitive hunters who used a blowpipe and darts to hunt wild animals.
3000 BC Man began to melt gold, copper, tin and lead found in pure form in nature and later to reduce their oxides.
Temperatures in excess of 1000oC required a more powerful compressor. This again was provided by nature with wind being compressed against a hillside and forced across a ridge.
Egyptian and Sumerian goldsmiths developed a blowpipe to provide a more convenient and reliable means of melting their metals.
The blowpipe is still used today, but is, of course, inadequate in
capacity for volume smelting of metals.
2500 BC Hand bellows, the first mechanical form of compressor, were invented.
1500 BC Foot bellows were invented
1000 BC Bellows were driven by water wheels.
1750 AD John Smeaton’s water driven air blowing cylinder, replaced bellows.
1776 AD John Wilkinson invented a cannon-boring machine. This invention enabled production of large, accurately machined, cast iron cylinders for both blowing machines and steam engines.
The first prototype was installed in his machine shop in Wilby, Shropshire, UK. It was limited to a pressure of about 1 bar(g) by the temperature capability of the leather links controlling the wooden valves.
The bellows and the early blowing machines were primarily used to supply combustion air for
smelting and to ventilate underground mines. This was necessary because the ore was mined by setting fire to the face and then cooling it with water to fracture the rock.
1800 AD People began to seriously think of compressed air as an energy transmission medium. It had already been found that steam was limited to short distances because it cooled and condensed so quickly.
1820 AD Metallurgical plants were growing in size and it was necessary to supplement installed steam
plants with water power. But, in Wales, a waterfall in the narrow valley could not be used as there
was no adjacent land on which to build a rolling mill.
It was decided to use the water to power blowing machines and to pipe the air to power air motors in the mill about 1000 metres away. Unfortunately on start up, although the blowing machines worked well, the air motors would not turn.
Compressed air technology very nearly ceased before it started.
Eventually it was found that the vitrified clay pipes, which worked well as water conduits, would not
hold air.
Compressor Fundamentals
A brief history of compressed air 1857 AD Since prehistoric times, man has worked with rock. Mining originated when flint was needed for
stone age tools. When mining progressed from lighting fires to blasting with explosives, it became necessary to drill holes in the rock. This was initially accomplished by hand, using the “hammer and twist” method.
Long distance transmission of compressed air energy began with the building of the Mt. Cenis railway tunnel in the Swiss Alps.
The 13.6km tunnel began in 1857 with manual drilling and would have taken 30 years to
complete. After four years, compressors were installed at both ends to power rock drills. When the
two teams met, there were 7km of distribution line running from each end.
The Mt. Cenis experience caused people to think about building distribution networks to provide compressed air energy to individual businesses.
1860 AD People began to develop mechanical rock drills.
It was shortly after that Ingersoll Rand began (as a result of individual efforts by Simon Ingersoll and the Rand brothers. Once the mechanical rock drill was operational, much work was done to develop reliable sources of motive power.
The air compressor developed quickly from this point
1871 AD
Patent No. 112,254 issued to Simon Ingersoll on 7th March, 1871. This is the date from which we trace Ingersoll Rand's history.
Ingersoll Rand Rock Drill in Kalgoorlie, WA
1888 AD Victor Popp, an Austrian engineer, gained a concession to run a compressed air distribution system through the Paris sewer system.
The plant was commissioned with 1500 kW of compressors feeding 7 km of mains and 50 km of feeder line.
1891 AD By this time, the system which operated at a pressure of 6 bar(g), had grown to a capacity of 18,000 kW (1.8 MW).
One of the major reasons for Popp’s success was a novel pneumatic clock which kept accurate time driven by timed pulses of compressed air. This became a “must have” item and once air was connected to restaurants, factories, shops, physicians surgeries, lawyers offices, etc., it became a simple matter to hook other pneumatic devices into the system.
Inventors in all parts of the work now got busy and many patents were issued. In Paris, for example, air was used for:
• Pneumatic clocks
• Pneumatic despatch systems
• Passenger lifts
• Wine and beer dispensing
• Air motors up to 70 kW to run tools, looms, presses, etc Factory in Paris that made
• Pneumatic drive of DC generators up to 36 kW to light air compressors for Victor
• Restaurants, theatres, hospitals, etc
Many reports concluded that compressed air was the energy transmission medium of the future. They took a very negative attitude to the electric distribution system then also in its infancy. There were others, however; who were equally enthusiastic about the merits of electricity and who dismissed compressed air because of its poor efficiency.
Neither of the two opposing schools of thought were proven totally correct. Compressed air plants kept developing and expanding. Electric transmission systems became the exclusive means of distributing power. Compressed air now serves as an important complement to electricity and it is called the “fourth” utility.

Dryer System Installation & Air Treatment
TS Refrigerated Air Dryer
A new non-cycling, refrigerated air dryer by Ingersoll Rand, the TS dryer is designed to improve reliability,
productivity and efficiency, protect health and safety and lessen environmental impact. To accomplish this,
the TS dryer incorporates several key technical innovations. Among these innovations are its 3-in -1 heat
exchanger(s), micro-channel condenser, microprocessor and"smart"drain
Features
• Reliability and performance
Consistently delivers dry process air with minimal pressure drop. 3-in-1 Heat exchanger integrates the pre-
coller and re-heater,heat exchanger and air/water separation to reduce the opportunity for leaks. High inlet
temperatures to 60℃ will be accepted with no nuisance shutdowns. Electrostatic-charged panel filter included
on all models for increased package performance.
• Productivity
Refrigeration Expansion valve offers more precise control under varying heat loads from the compressed air
and varying ambient temperatures resulting in less risk of product spoilage through dewpoint slippage.
Optimised connection sizes to minimise pressure drop. Intellisys microprocessor indicates component
warnings and if preventative maintenance is needed. Power Out Restart Operation(PPRO) improves
productivity.
• Energy Efficiency
"Smart"drain recognises ambient conditions to adjust dwell time and minimise the loss of valuable
compressed air. Energy Saving Efficiency Option to cycle refrigeration compressor is standard.
• Health, Safety and the Environment
Design uses environmentally friendly R404A. Less refrigerant is needed with MicroChannel condenser
design.

operated equipment while reducing maintenance costs.
These units efficiently remove solid particles from
compressed air lines making them the perfect choice for
large flow applications.
• Heavy Duty Regulators
These ARO Heavy-Duty Series regulators provide accurate
and quick response to flow demands and line pressure
changes, giving air-powered equipment the precise air
pressure control needed.
• Heavy Duty Lubricators
Extra rugged Heavy-Duty Series lubricators deliver the
reliable lubrication needed for long service life of air line
systems and equipment.
Receiver Tanks
The receiver tank is central to many industrial applications. In
factories using compressed air, the receiver tank helps deliver
stable output of compressed air, serves as a buffer, collects
moisture from cooled air and discharges it out of the system. The
air tank also serves as an air manifold to guarantee air supply in
peak hours. Ingersoll Rand provides air tanks in compliance with
applicable national codes and standards: stainless steel and carbon
steel air tanks; vertical and horizontal air tanks
Intelliflow Controller
Waste of the compressed air from leakage or improper regulation
is a common issue to most compressed air systems. IntelliFlow is
able to reduce the loss via precise control of the operating pressure.
Benefits
SAVE ENERGY: Stabilize demand side pressure at minimum
acceptable level
INCREASE PRODUCTIVITY: Provide consistent repeatable tight
pressure control
ENHANCE RELIABILITY: De-couple supply side from demand
side
INCREASE RELIABILITY: Eliminate rapid cycling of
compressors
SimplAir
SimplAir is a high-performance modular aluminum piping system
that is easy to install and simple to extend or modify. The non-
corrosive extruded aluminum provides structural strength and
delivers contaminate-free air in a leak-free piping system. The
smooth bore of SimplAir tubing prevents high-pressure losses and
allows for higher flow rates and performance than that of
conventional piping systems. The positive O-ring seal ensures that
no leaks occur at any stage of the system's life. No air leakage
ensures minimum running costs.
