A commercial kitchen can remain smoky, hot, or filled with cooking odors even when the visible hood looks clean. The problem may be farther along the exhaust path. Grease on the rooftop fan, restricted ductwork, damaged filters, poor makeup air, or a mechanical fault can all weaken the kitchen exhaust system\u2019s ability to capture cooking exhaust.<\/p>\n\n\n\n

The rooftop fan creates the pull that moves air from the cooking line through the hood, filters, plenum, and ductwork. At the end of the grease-bearing path, the blades and housing can collect grease passing through the filters and ducts.<\/p>\n\n\n\n

Restaurant owners should know what the fan does, how to recognize signs that it needs attention, and what proof shows that it was opened and serviced during the last cleaning.<\/p>\n\n\n\n

This article covers fan operation, warning signs, cleaning scope, safe access, service documentation, and NFPA 96<\/a> expectations in the states of Connecticut and New York.<\/p>\n\n\n\n
