Benefits and Features 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). Operation Animations Application Areas 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 and other non-toxic or non-flammable liquids – VS1C series
