Product Description:
Float operated, the air is collected in the Flexvent causing the float to drop and open the air release valve. The water pressure then pushes the air out, the float rises and closes the valve.
The air cushion in the upper part of each Flexvent protects the valve seat against contamination.
Most types are equipped with a shut-off valve for easy fitting and dismantling.
