Flamco Air Vent Flexvent Straight

Automatic air vents have high efficiency and guaranteed operation in heating and air conditioning systems. The water system contains air, which can cause corrosion and reduce heat transfer. Flexvent is installed in places where air accumulates. Since the device is operated by a float, the air that accumulates causes the float to sink and open the air vent. Once the air is expelled, the float rises and closes the vent.
