Best Answer

The compressor compresses air and send it to either a wet tank or directly to the air dryer. Oil and moisture in the compressed air are absorbed by the desiccant in the air dryer canister. When the compressor signals cut out, it also send a signal to the dryer to open the purge valve, which purges the canister.

How often the air dryer has to relese the air on a semitruck?

there is no set time for the air dryer to release,however, the more himidity in the air, the more often it will release. the dryer is actually dumping moisture with some air ,but mainly moisture. if you dump the airtanks and they relaes a lot of water, the dryer is not working properly the dryer releases it when the governor tells it to the governor does not dump the air. the governor is on the engine and tells the air comprssor when to pump air and when not to pump air. a lot of trucks do not have an air dryer installed,and theses trucks need the tanks dumped manually at least once a day
