These honeycomb grease filters are made from high quality aluminium throughout. The filter media is made from 50mm wide aluminum foil, which is specially corrugated into a herringbone shaped channel. This foil when placed one on top of the other will form a curved honeycomb channel. When the incoming grease laden air passes through this media, the air changes direction. The resultant change in inertia causes the grease to cling and condense onto the aluminium surface. This prevents grease from entering the exhaust system. This honeycomb media is encased in a 50mm thick aluminium frame.

All frames have drain holes for the cooking fat to drain in to the canopy channels. All filters are fitted with steel plated retractable handles. Large D handles, which are fitted offset, are also available at an additional cost. Honeycomb filters are fully washable panel filter units.

They provide extremely low resistance to air flow and ease of cleaning.
