  • Complete drain system Designed for most vacuum systems
    Isolated trigger assembly Reliable design – unaffected by contaminants
    Heavy duty industrial drain One unit works for multiple compressed air systems. Saves valuable air. Saves money
    Horizontal low profile Fits in tight spots – can be mounted under equipment
    Translucent reservoir Easy-to-see condensate level. “Quick check”
    Non clogging, full port drain valve Handles scale and rust without clogging
    Fully pneumatic No electricity required
    Automatic design Operates on demand
  • 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.
