The Expello Electronic Drain Valve provides increased durability and reliability for constant protection from build-up of harmful contaminants in air tanks on trucks, trailers, buses, RV’s and other vehicles.
This drain valve expels contaminants every five minutes of operation with a powerful one-second blast of air. The electronic controls and 50 watt heater provide year round protection. The corrosion resistant construction ensures maintenance-free operation over the long haul. Once installed in place of the manual drain petcock on the tank, the valve’s straight through contaminant flow and self-cleaning design provide air tank draining without daily checks.
