π§ Why do automatic condensate drains fail?
One of the most common causes of moisture problems in a compressed air system is a clogged automatic drain.
Traditional solenoid drains rely on a small or***ce that can easily become blocked by compressor oil, rust, pipe scale, and debris. When that happens, condensate builds up inside your air receiver, air dryer, filter, or moisture separator, leading to corrosion, equipment damage, poor air quality, and unnecessary maintenance.
The Midwest Controls MD Series Motorized Ball Valve Automatic Condensate Drain is designed to solve this problem.
Instead of a small or***ce, it uses a full-port forged brass motorized ball valve that opens completely during each drain cycle, allowing dirty condensate to pass through with minimal risk of clogging.
