The Expello® Air Products Pneumatic Drain Valve provides long lasting, durable air systems protection.  This drain valve expels build-up of harmful contaminants in air tanks on trucks, trailers, buses, RV's and other equipment with compressed air systems.  No system eliminates all the moisture from the wet tank all the time.  This drain valve expels contaminants from your air tank with a powerful blast of air whenever your compressor reaches cut out an at compress cut in.  It can be mounted in vertical or horizontal to fit into tight places. The 50 Watt heater with built in thermostat provides year-round protection even in the coldest conditions.
