These automatic air vents eliminate residual air in heating and air conditioning systems without the need for manual intervention. This prevents undesired noise, wear of devices in the circuits and inefficient performance of heating units.

The vents have a built-in anti-rotation and anti-vibration system. The float is fitted so that when it is in rest position the obturator is not affected by any external movement. The positioning of the float and the internal parts are also such that the water never reaches the obturator itself. This prevents faults caused by the infiltration of impurities present in the fluid.

Our automatic air vents (CA-100099) come with a ½” check valve that makes maintenance and inspection of the air vent easier by shutting off the flow of water when the valve has been removed. O-Rings in EPDM ensure a good seal with the valve body.
