2901146551 Electronic Condensate Drain Valve Atlas Screw Air Compressor

Product Introduction

Condensate belongs in the drain line, not pooling in the receiver or washing downstream filters. 2901146551 is listed as the EWD 330M electric drain kit, cross-referenced with 1622855181, built for automatic condensate discharge on oil-injected screw compressors, dryers, and air receivers. Timed or level-controlled dumping keeps water, rust, and oil-water emulsion out of the air system while preventing unnecessary air loss from a stuck manual drain.

A failing drain shows up as water at the farthest outlet, rising bowl pressure, chronic filter saturation, or continuous blow-by from a stuck solenoid. Replace the kit during service, check the strainer and discharge line, and confirm voltage before wiring—this configuration is quoted for 115VAC. Route the drain line downward with no trapped loops, and keep the outlet clear so backpressure cannot hold the valve closed.

Match the kit to machine model and serial before dispatch; electronic drain fittings and harness options change between packages. Also called electronic drain valve, auto drain kit, condensate drainer, EWD drain module.
