ECOAIRTM Commercial Kitchen Hoods integrated with UV-C & Eco-curtain Controlled Capture Air Curtain technology uses powerful UV-C rays to create ozone behind the hood filters – filling the entire hood. Generated ozone decomposes and oxidizes organic fat particulates exhausted through the hood, resulting in safer, cleaner, more efficient hood operation. Our hoods utilize a compact, multi-scattered-lamp cassette, located outside the direct air stream for maximum ozone effect and cassette life.
