Mazzei Venturi

Size on motive water flow through the injector and the inlet-to-outlet pressure drop — most models begin drawing gas once the outlet pressure is at least 20% below the inlet pressure, so tell us your pump flow and available differential and we will confirm the model and its flow range.

Yes — it is used for oxygen, ozone, air, carbon dioxide and liquid chemicals, and the micro bubbles it creates greatly increase the gas-to-liquid contact area.

Match the injector to your motive water flow at the available pressure drop, then check that the inlet, outlet and suction connections suit your pipework.

It is a differential pressure injector — the drop across the venturi is what creates the vacuum that draws gas in through the suction port.

No — there are no moving parts, which is why the injectors are effectively trouble-free in service.

6 mm and 12 mm barbed or MNPT threaded ports on the smaller bodies, a 32 mm MNPT port on the 2081A, and dual 1.5″ male BSPT ports on the 3090.

Many micro bubbles carry far more surface area than one large bubble of the same volume, so gas transfers into the water much more efficiently.
