A Test and Drain is a type of with both a function and an express function. Think of a ball valve and inspector’s test valve combination, except it’s manufactured as one unit, making it much more convenient.
A drain valve performs the critical function of allowing excess water vapor to escape into the atmosphere. The removal of condensation helps prevent the formation of corrosion that will eventually damage the compressor and shorten its lifespan.
Having a drain valve is necessary as water vapor condenses into liquid and drops to the bottom of the air tank. The drain valve then helps to remove the water that has been accumulated at the bottom of the tank before it causes significant damage to the compressor.
