Automated Air Venting During Operation: Air entering the automatic air vent is rapidly discharged, even during water or liquid transport or during operation.; The float responds with great sensitivity to condensate levels, automatically opening and closing the valve and thereby eliminating the need for manual labor.
Long Service Life: The float is the only moving part. Simple design, with no hinges or levers.
Tight Sealing: The grounded float and rubber valve seat prevent leakage (VC series).; The precision-grounded float and 3-point seating prevent leakage (VS1C series).

For use in applications requiring the steady discharge of air – both initial air and air generated during operation.

For applications requiring the discharge of large quantities of initial air, also install a rapid initial air vent.

Main Applications: Air conditioning facilities, solar systems, water transport lines, water storage tanks.; Transport of and facilities using other fluids.; Water, hot water – VC series; Water, hot water, other liquid other than toxic or flamable – VS1C series
