View of Right Side Platform (1) Air Dryer | |
The air dryer (1) is located under the right side platform next to the air tank. Air flows from the air compressor to the air dryer. The air dryer removes the contaminants and moisture from the air system.
When the air compressor governor reaches the cut-out pressure, the air compressor governor sends an air pressure signal to the purge valve in the bottom of the air dryer. The purge valve opens and air pressure that is trapped in the air dryer is exhausted through the desiccant, an oil filter, and the purge valve.
A relief valve is located on the air dryer in order to protect the air system if the air compressor governor malfunctions. A heating element in the bottom of the air dryer prevents moisture in the dryer from freezing in cold weather.
