Automatic Air Volume Control for
Pressurized Water Storage Tanks

The Mazzei^® Automatic Air Volume Control features a high efficiency Mazzei^® Injector installed in a bypass assembly with an adjustable, spring loaded, flow control valve and a float air volume control installed inside the tank. A tube connects the injector suction to the float air volume control valve. The float air volume control opens as the water level in the tank rises, and air is permitted to be sucked into the water stream through the injector. The aerated water recharges the depleted air and prevents water logging of the pressure tank.

The assembly features a Mazzei^® Injector molded of PVDF and schedule 80 PVC fittings for added strength. The pressure differential is achieved by an adjustable flow control valve, allowing it to be matched to the requirements of the presure system. Union fittings are used to permit removing the injector for servicing or replacement.

Look for The Mazzei^® Design . . . Because It's What's Inside That Matters!
