   Compressed Air System Network and Components


Prevent dust and other contaminats from entering air compressor.

The filtered air is compressed ( typically 80 psig [5.5 bar] ~ 110 psig [7.6 bar] ) using different types of air compressor such as reciprocating, vane, screw or centrifugal.




A.Compressor Type - Recommendation:
0 to 80 psig (5.5 Bar) : single stage air compressor
80 to 250 psig (17.2 Bar) / continuous usage of tools : two-stage air compressor


B.Total Air Consumption - Determine the total demand SCFM
Factors to consider: demands of all air tools, equipments, and other air consumption variables.


C.Air Compressor Capacity - Horsepower (HP)
Determined total demand SCFM : D
and add approximately 20% for system variables. Add ? % for future growth. : D1 = D x 1.2
If D1 <= 100 SCFM : hp = D / 4
If D1 > 100 SCFM : hp = D / 5


Compression leaves the air hot and wet. The Refrigerated Dryer can reduce the temperature of the air and removes the excessive water.

Air Receiver is provided as storage to reduce fluctuations and maintain a smooth flow in the compressed air system. Receiver Tank Size - The more receiver the better the system.


The link between supply, storage and demand. To supply adequate amount of compressed air at the required pressure to all work station.


Filter-Regulator-Lubricator (FRL):
FRL are needed to ensure that an air tool is receiving a clean, lubricated supply of air at the proper pressure. The filer removes water, pipe deposits, rust and condensation from entering the air motor. The regulator controls air pressure to the tool. The lubricator provides a nearly constant oil/air ratio of air flows. The oil drip rate: one drop per minute for each 20 SCFM (566 LPM)

   Factors Relate To Adequate Air Flow


1A hose of excessive length and / or insufficient diameter can restrict the air flow.
2If you are using an air tool on a hose over 25 ft (7.6 M). long,
it is advisable to increase the bore of the hose to the next larger size available, ie. 1/4” increase to 3/8”.
This will ensure adequate pressure and volume of air to power the machine.
3Usage of air inline filter / regulator
4Total number of air connections / fitting being used
5Prevent any blockage of air flow. Maintain adequate air flow.
6Remove or reduce condensation from the air supply.
7Regular check for leaks in all piping, joints, drains, relief valves, flexible hoses.
8Water in the compressor tank will cause serious corrosion to your air tools and should be drained daily to
avoid excessive water in your air supply. Dirty wet air will rapidly shorten the life of your air tools.
9Supply tool with 90 psi (6.2 bar) of clean, dry air. Higher pressure drastically reduces tool life.
10Do not install a quick coupler directly into the tool throttle handle.
11Prevent contaminates from entering the air motor.
12Every day before use, remove the tool from air line and pour 20 cc suitable motor lubricating oil into Air Inlet.
Run the tool for few seconds to allow air to circulate the oil and well lubricate the cylinder.
This will ensure top performance and maximum durability of tool.
13Lubrication : Use an air line lubricator with SAE#10 oil, adjusted to 2 ~ 3 drops per minute. If an air line lubricator can not be used,
add air motor oil to the inlet before and after use. Gears, bearing, sleeves, and sliders need to be lubricated as well.
14Dissemble and inspect air motor and governor assembly every 3 months if the tool is used every day.
Replace damaged or worn parts.
15Use original factory supplied tools, spare parts and accessories.
16Do not alter or modify the unit from the Original design or function.
