G0442HEP 5 HP Dual-Filtration HEPA Cyclone Dust Collector

The best of the best Grizzly dust collectors!

The G0442HEP 5 HP Dual-Filtration HEPA Cyclone Dust Collector is geared toward those looking for the best filtration on the market.

The dual-filtration starts with the primary filter with efficiency of 99.9% at 0.2-2 microns and finishes at the secondary, HEPA filter with efficiency of 99.97% at 0.3 microns in size.

The advantage of this dual filtration setup is the majority of all fine dust is captured by the first filter and only the finest dust makes it to the HEPA filter.

Cyclonic action separates the heavy dust particles from the fine particles and drops them into the 55-gallon steel drum. The fine dust travels past the 16" diameter impeller and is then trapped by cartridge filters made of spun-bond polyester.

The cartridge filter is pleated to provide 226 square feet of surface area for efficient air movement and a clear plastic bag collects the fine cake that shakes off the filter for consistent dust collector performance.

Casters mounted to the drum also make disposal of the larger chips and dust as easy as it gets. A rugged steel stand is included.

Like all Grizzly machines, the G0442HEP comes with a 1-year warranty which covers parts and assures the unit is free from factory defects.

The G0442HEP manual was written by our U.S. based Technical Documentation Department and is packed with useful information.

The Grizzly Customer Service and Technical Support Teams are U.S. based. Parts and accessories for your machine may be available online and shipped from the Grizzly parts warehouse in Springfield, MO.
