Hydrant Air Exhaust (HAX)

The Hydrant Air Exhaust (HAX) utilizes the proven technology of an Av-Tek® Air Release Valve to make filling water lines simple, controlled, and flood-free. Eliminate the time-consuming task of monitoring hydrants during pressurization—install the HAX and return once the system is fully pressurized and air has been safely exhausted.

Designed with a multi-port configuration, the HAX enables efficient pressure testing and water quality testing in locations that were previously inaccessible with traditional setups. It also helps relieve trapped air that can cause pressure spikes within your system.
