Some attentions of desicant air dryer (heatless type) maintenence

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, in fact there are many different problems  such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using  time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended  maintenance   in some factories is not seriously followed and there are deviations. To extend the life of the machine as well as compressor components and ensure operate safely Air compressors are very important to maintain regularly and technically correct.Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduced use time of compressor accessories (air filter, loc oil, oil separator ...). On the other hand, the maintenance (maintenance) recommended by the manufacturer in some factories is not guaranteed and there are deviated. To lengthen  longevity  of mạchine as well as compress

Working principle of air filter and pressure regulator

principle of air filter and pressure regulator

Compressed air is directed into the filter from the pipe connected to port P1. The spiral plate will cause turbulent air flow. Because of this whirlpool, dust particles and water in the compressed air will be subjected to centrifugal force and outward movement, hitting the inner wall of the filter cup and flowing to the bottom of the filter cup. Air flows through the air filter, where they are filtered again before flowing to the pressure regulator. The condensate is discharged through the exhaust valve. Based on membrane correction, by rotating the adjustment screw, the tapered seal will allow more or less compressed air to reach the output port P2. If P2 side pressure is higher than P1 side, the film will be pushed upward. The compressed air will escape in the atmosphere through a small hole in the cap. It is visiable monitor pressure from manometer.

Some units may be corroded:

 + Filter
 + O- ring13
 + Membrance.
 + Rubber.
 +  O- ring23
 +  O-ring 28.

Damage, causes and remedies:




Air filter can not separate dust and water.

- Filter is improperly installed .

-The level of substrate in the filter  is higher than the allowance.

- Install filter in the right direction regulated flow.

- Install draining discharge, install automatic discharge. 

The air escapes into the atmosphere at the pressure regulator valve.

The pressure regulator is mounted in the opposite direction (the input port and output port are interchangeable).

Replace the pressure regulator properly.



Filter cartridges must be cleaned after a period of operation.
Regularly check the maximum water level in the filter cup.
Do not place pressure above 1600kPa into standard pressure regulating valve (manufactured with technical standards).
