Electronic Expello Drain Valve


Automatic drain valves provide long-lasting air system protection by removing moisture and other contaminants from 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. Electronic drain valves provide reliable protection of air system components and help eliminate issues such as frozen air brakes.

Automatic Drain Valves for Air Compressor Systems

Expello® Air Products Automatic Drain Valves purge 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, even during the harsh and cold winter months. These electronic drain valves offer the versatility of mounting horizontally or vertically to fit into tight places.
