Product Type: Drain Valves
Expello Electronic Drain Valve

The Expello Air Products Automatic Drain Valve eliminates moisture in compressed air systems. The valve replaces the manual drain petcock on any air tank within a vehicle’s compressed air system, whether the tank is on a vehicle or trailer. The Expello valve purges water, dirt and oil from the air system in a quick, 1-second burst, every 5 minutes of vehicle on time. That means clean, dry air and an end to frozen air brakes. The 15 watt thermostatically controlled heater ensures year round air system protection.
