Ai SuperVac dual-stage rotary vane vacuum pumps have an ultimate vacuum rating of 0.3 micron.

They are designed for reliable long-term operation and come standard with connection fittings and a high-capacity oil mist exhaust filter that returns trapped pump oil back into the oil casing and also makes the pump quieter during operation.

Each pump includes adjustable gas ballast to dilute aggressive chemical vapors that may re-condense inside the pump. This also helps alleviate moisture, solvents, and other contaminants from building up inside the oil casing.

We carry three different models of the SuperVac rotary vane vacuum pump, each with different pumping speeds:  5.6 cfm, 11.3 cfm, and 21 cfm.
