PURGEnVENT Model 7900AAV Automatic Air Vent

AGF's PURGEnVENT Model 7900 Automatic Air Vent (AAV) is a 1" ball valve, strainer, and purge assembly that helps prevent corrosion. The patented, one-piece isolation valve is designed to vent air with no leaks, meaning no need for drip pans or drain lines. It also includes a barrel strainer and purge valve with hose thread to allow for rapid purging of air from the pipes as the system is filling and the venting of excess air once the system is filled. The purge valve doubles as a vacuum break when draining the system. AGF recommends installing Model 7900AAV at the high point of the system, at the end of branch lines, and on top of supply risers.
