Type I Commercial Kitchen Ventilation CKV hoods provide a means to capture, contain, and exhaust grease-laden air and exhaust gases. CKV hoods are designed so that as little grease as possible is allowed to collect in the Hood and/or Filters. As the filters remove the grease from the airstream, it drains into a pitched filter grease drip tray which then drains down to an enclosed metal container, Grease Collector, with a capacity of no more than 3.8L (1 gal).
UL 710 also requires that the Type I CKV Hood be equipped with a Drip Tray beneath the lower edges of the filters that is kept to the minimum size needed to collect grease, and pitched to drain into an enclosed metal container having a capacity not exceeding 3.8 L. (1 gal). UL 710 offers no exceptions to this requirement.
