The PM60 EasyVac Aspirator has a high performance 1/5 horsepower pump that delivers 0-26 inHg (0-660 mmHg) - among the highest in the industry.

It's Protected.

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 Easy Vac has a protective canister bracket which not only holds the canister but also protects the gauge and adjustment knob from accidents.

It's Convenient.

The Easy Vac has a Velcro™ strap that allows the power cord to be wrapped securely to make portability easier. Extra strength premium suction feet attach the unit safely and securely to most surfaces, preventing spillage.

It's Safe.

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