A dual protection system consists of a float shut-off in the canister lid and an Inline Hydrophobic Filter to prevent back flow of fluid as well as airborne contaminants from entering the pump.

It's Durable.

The Power Vac's ABS plastic cabinet is durable, attractive, easy-to-clean and infection control friendly.

It's Convenient.

It's Safe.

Safety is assured with the automatic resetting thermal limit switch which prevents the unit from overheating.
