  • Translucent reservoir 
  • Non clogging, full port drain valve 
  • Automatic design 

Benefits

  • Ideal for most compressor installations 
  • Reliable design – unaffected by contaminants 
  • One unit works for multiple compressed air systems. Saves valuable air. Saves money 
  • Fits in tight spots – can be mounted under equipment 
  • Easy-to-see condensate level “Quick check” 
  • Handles scale and rust without clogging 
  • No electricity required 
  • Operates on demand 

How it Removes Condensate From Compressed Air Systems

Condensate enters the drain through one of two inlet connections. As condensate is collected and the translucent reservoir fills, a stainless steel float mechanism rises. When the condensate reaches a design level, the float mechanism actuates an isolated magnetic trigger assembly. The trigger assembly directs control air to the valve actuator, which in turn opens a full-port drain valve.

Condensate will then exit the unit. As the float drops, the trigger assembly closes the control air line and the valve actuator closes the ball valve. The drain is then returned to the collection mode.
