SCHOFIELD, Wis. - The U.S. Patent and Trademarks Office has issued a patent to Greenheck for a two-stage air purification system its engineers invented for installation and operation within a kitchen ventilation hood.

The Grease Grabberâ„¢ (GG) multi-stage filtration system is available in Greenheck kitchen hoods and uses the Greenheck Grease-X-Tractorâ„¢ (GX) filter along with a secondary filter to remove 80 percent of the grease from the airstream, says the company. The GX is the primary filter and takes the brunt of the grease and heat, using centrifugal impaction to remove large grease particles. The secondary filter uses a 1/2-inch packed bead bed to remove, by interception, the small particles of grease that are not removed by the GX filter. The GG filtration system utilizes these two filters to remove 100 percent of the particles that are eight microns or larger in diameter and 80 percent of the particles that are three microns in diameter, the company says.

Greenheck's patented dual filtration system helps eliminate costly repairs and maintenance by filtering out more of the grease within the hood, which results in less grease accumulation in the ductwork and on the roof, the manufacturer says. The dual filtration system will also help meet emerging air quality regulations. Both filters in the new filtration system are designed to be easily removed, washed, and returned to the hood for efficient operation.
