Air dryers are installed between the air compressor and the "wet tank" on commercialtrucks and motor coaches. Their purpose is to filter out water vapor, oil vapor, and other contaminants before they can reach the air tanks and valves. This helps prevent freeze-up during the winter and extends the life of air valves.
