Zero Air Loss Auto Drain
One.ki® Zero Air Loss Condensate Drain, a motorized ball valve type used in draining compressor air tanks, dryers and filters. Auto drains are used to replace manual drains that are normally standard equipment on compressor tanks.
ZERO AIR LOSS = Saving Energy
REMOTE MONITOR when clogged or overload
NO loose parts inside tank, extremely LOW breakdown rate
MAXIMUM Drain Volume + SUPER Design = EASY Operation & LONG Life Span

The diameter of the discharge channel inside the ball valve is 10mm. Even iron fillings can be discharged easily without Y type filter. Straight discharge channel where contaminant discharged with condensate. Discharge even when pressure is zero so compressor can operate continuously without down time.

Stainless steel as the main part of zero air loss condensate drain provides comprehensive protection, reduce corrosion effect and extend the operating life.

Sensor detects increased water level and automatically signals the ball valve to open. Cost savings, without diaphragm cost. Manual operation when power fail. Flexible, reliable and safe.
Schematic

(1) Condensate flows into the unit and water level rises.
(2) Sensor detects high water level and discharge condensate by opening the ball valve automatically.

(3) Sensor signals the valve to close when discharged condensate down to low water level.
(4) Water seal prevents air leakage when the valve is closed.
