   Compressed Air System Network and Components

 

1.INTAKE AIR FILTERS
Prevent dust and other contaminats from entering air compressor.

2.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.

 

AIR COMPRESSOR SELECTION CRITERIA :

 

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

 

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

4.RECEIVER (AIR STORAGE TANK)
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.

 

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

 

6.POINT-OF USE APPLICATION :
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)

*FAQ
   Factors Relate To Adequate Air Flow

 

1 A hose of excessive length and / or insufficient diameter can restrict the air flow.
2 If 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.
3 Usage of air inline filter / regulator
4 Total number of air connections / fitting being used
5 Prevent any blockage of air flow. Maintain adequate air flow.
6 Remove or reduce condensation from the air supply.
7 Regular check for leaks in all piping, joints, drains, relief valves, flexible hoses.
8 Water 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.
9 Supply tool with 90 psi (6.2 bar) of clean, dry air. Higher pressure drastically reduces tool life.
10 Do not install a quick coupler directly into the tool throttle handle.
11 Prevent contaminates from entering the air motor.
12 Every 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.
13 Lubrication : 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.
14 Dissemble and inspect air motor and governor assembly every 3 months if the tool is used every day.
Replace damaged or worn parts.
15 Use original factory supplied tools, spare parts and accessories.
16 Do not alter or modify the unit from the Original design or function.
