NFPA Standard-96 requires that a 3" x 5" (or 4" circular) fan access panel be installed on the curvature of the exhaust fan bowl, allowing for all areas of the fan to be thoroughly inspected & cleaned. Fan access panels allow EHS Technicians to clean the back side of the fan blades which are not normally accessible. Our services are Guaranteed, that’s why is very important to following our recommendations. Not having a fan access panel can cause grease build-up on the blades resulting in the fan being off balance, leading to fan vibration or rattling. Over time this can cause premature wear on the bearings & belt and can degrade the effectiveness of the exhaust fan.
