My Dryer Has a Timer Drain and Keeps Losing Air

Problem: My dryer has a timer drain and keeps losing air. How do I fix this?

Solution: Pneumatech's No-Air-Loss Drain is the industrial standard for reliable condensate management with superior quality and perhaps the simplest and most cost-effective way to prevent wasting tremendous amounts of energy. The no-air-loss drain is the only true zero-air-loss-drain on the market and provides several distinct advantages over the competition:

  • No unnecessary loss of compressed air
  • Discharge adapts to condensate quantity
  • Sensor registers every type of condensate
  • Unaffected by dirt
  • Low maintenance
  • Fully automatic monitoring

How does it work?

Empty State (left) Filled State (right)

Empty State
  1.  Consensate enters side inlet port.
  2. Condensate level begins to rise.
  3. Condensate level activates sensor.
  4. Sensor signals control board. Control board activates solenoid valve. Solenoid valves stops pilot air flow to diaphragm. Condensate pushes diaphragm open.

Filled State

  1. Open diaphragm provides condensate discharge path. Condensate discharge begins. Reservoir level beings to fall. Reservoir level drops below sensor. Sensor deactivates solenoid valve. Pilot air closes diaphragm before level drops below discharge port.
  2. Condensate discharge completed. Reservoir begins to fill and cycle repeats.
