Electronic valves
Purge contaminants from vehicle air systems in a one-second burst.
A one-second air burst is the electronic drain valve's method for purging contaminants from vehicle compressed air systems. Expello Air Products makes automatic drain valves for air tanks on trucks, trailers, buses, RVs and other equipment, as well as shop air compressors. Its electronic valve purges on a timed cycle, while the pneumatic model operates as the compressor cycles. Both replace manual drain petcocks and remove moisture and other contaminants from compressed air systems. The shop valve automatically drains moisture from a compressor storage tank. Product options include different inlet sizes and electrical configurations; some models include thermostatically controlled heaters for cold-weather protection. The company's website lists a three-year warranty for its drain valve components.
