Air dryers are essential for air compressors. They keep compressors free of moisture, and prevent condensate and rust problems from occurring. ... Accumulation of this moisture, over time, can cause serious damage to the compressor. It can corrode valves, pipes and even machinery controls.
If you wanted a properly sized dryer from one example supplier, you should add 51% for the high inlet temperature, about 5% for the lower pressure and another 16% for high ambient temperatures. This would result in a dryer rated at about 500 x 1.51 x 1.05 x 1.16 = 920 cfm.
Nevertheless, how do I keep moisture out of my air compressor? Common practices to remove moisture from compressed air include:
Draining the tank.
Using a water trap and filter regulator.
Using a refrigerated air dryer.
Using a desiccant air dryer.
Using a deliquescent air dryer.
Through piping system air drying.
With the storage tank cooling method.
Through absorption drying.
Likewise, how do I test my air dryer?
How does an air dryer compressor work?
Compressed air dryers are special types of filter systems that are specifically designed to remove the water that is inherent in compressed air. ... As the compressed air cools, water vapor condenses into the tank(s), pipes, hoses and tools that are downstream from the compressor.

The purpose of air dryers is to suppress the dew point of your compressed air by removing water from it. Compressed air can contain moisture, which, under the right conditions, can reach the dew point temperature and condense into a harmful liquid.
When a compressor draws in air, the air is compressed to about 12 times normal atmospheric pressure. Pressurized air is not able to hold as much water. As the pressure increases, water vapor condenses back into a liquid. ... If water is allowed to accumulate, moisture may get pulled back into the compressed air stream.
Although manufacturing defects can caused a tank to explode, the leading cause of air compressor tank rupture is corrosion of the tank from water condensate. ... This will prevent moisture from entering inside the tank and corroded.
All atmospheric air contains some water vapor, which will begin to condense into liquid water in the compressed air or gas system when the air or gas cools past the saturation point, i.e., the point where it can hold no more water vapor.
1 Answer. It is a good idea to drain the air compressor periodically. Part depends on how much you use it. My grandfathers tank hadn't been drained for years (I think after he quite using it but everyone else still did) and it had 20 gallons of water in it.
When the air pressure becomes greater than that of the preset “cut-out”, the governor controls the unloader mechanism of the compressor to stop the compressor from building air and also causes the air dryer to purge.
