Kason's Trapper® Dual Action Grease Filter is for commercial cooking hoods. This economical and efficient filter, cleans fast and easy. The two-piece construction combines baffle plates and frame into one solid metal unit; there are no loose baffles to rattle or fall out. The smooth, aerodynamic baffles pick up more airborne grease and promote better drain-off. The solid galvanized steel construction insures a dependable flame barrier. The efficient grease removal reduces risk of flare-ups. The strong, light-weight Trapper filter is easier to handle, install and clean than other grease filters on the market. The grease filter has great strength and durability, meaning longer list and fewer costly replacements that ordinary baffle-type filters. The filter has easy installation and fast clean-up, reducing maintenance costs. The filter is fully interchangeable with existing filters.
