The Humm•Vac™ vacuum pumps are available in three models. The HVP 6CFM (yellow), HVP 8CFM (red), and HVP 12CFM (black) units are innovative in design, said the manufacturer. The pumps feature a wide, sure-footed chassis, a slant back ergonomically balanced handle, an easy-access top-mount isolation valve, a large oil-level sight glass, an accessible gas ballast, and a low-profile beveled oil drain. The powerful, quiet running 110/220V, 50/60-Hz motors provide a deep vacuum pull that remove moisture and dehydrate a system quickly and efficiently.
