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 compressor components and ensure operator safety , air compressors are very important to maintain regularly and technically .

Period	Checkpoint	Method
Start up	Pressure indication	All pressure gauges -Drying tower pressure: Same line pressure -Purge pressure: 3.0-3.5 barge -Regeneration tower pressure: Below 0.5 barg
	Solenoid & pneumatic valve	Operation check
	Back pressure on regeneration tower	Max 0,5 bar. If needed clean the silencer
Every 3-4 months	Pre-filter and after filters	Inspect pre-filter and after-filter for dirt, oil and other contaminants. Replace if contaminated.
Every 3-4 months	Control air filter	Inspect filter element or regulator if needed clean the filter and regulator.
Every 6 months	Calibrate dew point meter (if installed).	Refer to dew point meter owner’s manual.
	Inspect the silencer.	Replace exhaust silencer if back pressure on regeneration exceed 0,5 barg.
	Inspect solenoid valves.	While dryer is operating, inspect solenoid valves. If leak or malfuntion persists, replace valves.
Yearly.	Replace filter elements.	Replace pre-filter and after filters.
Yearly.	Inspect and replace pneumatic valve.	Inspect valve seating and valve internals, if needed clean or replace the valve.
