Pulse-Bac 552H Compact Industrial HEPA Vacuum

Every Pulse-Bac runs Pulse-Bac's patented Automatic Pulse-Clean Technology™. While you work, the vacuum briefly reverses airflow through its filters to knock loose the fine dust that would otherwise cake on and choke suction. There's no air compressor to drag along, no manual shaker, and no stopping the job to clean filters, so suction stays consistent through long grinding and prep runs.

The 552H adds a second HEPA filter on the motor exhaust behind the primary filters. Both stages are individually tested to 99.97% efficiency at 0.3 microns, giving you an extra layer of protection when you're working with concrete, silica, or other hazardous dust.

Pulse-Bac collection tanks are made from 16-gauge cold-rolled U.S. steel, not molded plastic, and hold up to jobsite abuse that cracks poly tanks. Every Pulse-Bac vacuum is designed and assembled in Tulsa, Oklahoma.

Auto Tool Start is standard on the 500 Series. Plug your grinder or other power tool into the vacuum and it turns on when the tool starts and off when the tool stops, so dust collection is always running when you're cutting and you're not walking back to flip a switch.

The 1.5" locking inlet holds the crush-proof hose in place while you work, so it won't pop off mid-cut and the seal stays tight for full suction. It's sized for hand grinders, hammer drills, and other handheld tools.

Pulse-Bac's Cyclonic Debris Management system is standard on its tanks, drum extenders, and preseparators. It works with pulse cleaning to keep up to 90% of dust and debris from ever reaching the filter, and holds it at the bottom of the tank so it isn't pulled back up into the filters.
