A dryer is a necessary component of an air compressor if the goal is to maintain a low moisture level in the air. Some people may have questions about the dryer, however. Here are some of the most frequently asked questions about Air Dryers in PA.
How does moisture get into the compressed air?
Moisture enters the compressor through the inlet air filter. The compressor takes in roughly seven cubic feet of air, which is then compressed to one cubic foot. The trapped moisture is also compressed and results in a small amount of water in the compressor. The water that is trapped can take on one of three forms: liquid, gas, or mist. If the water is liquid, it is simply and quickly removed by an air-water separator. These devices can remove approximately 99 percent of the water. If the water is in gas or mist form, it is more difficult to remove and requires the use of an air dryer. Using a dryer prevents moisture from forming downline and causing damage to the system.
What type of dryer should be used?
This depends on the dew point. This is the measurement of air dryness that is appropriate for the machine being powered by the compressor. Contact the manufacturer of the machine to find out what the exact pressure dew point should be. if the manufacturer cannot be contacted for some reason, the dew temperature can be taken manually. To do this, check the air lines to find the lowest temperature that the compressor piping system will be exposed to. Lower that temperature by 20 degrees.
How does a dryer work?
It works via a heat exchange where the incoming air is cooled to approximately 38 degrees. This condenses the moisture into water. The water is then drained away.
