Exhaust Fan Hinges

The fire codes recommend exhaust fans to be hinged, allowing thorough cleaning of the fan and the duct below it. Hinging the exhaust fan is not only recommended, it will also help to significantly increase the life of the fan.

Exhaust fans are made of very soft aluminum and can be damaged during the cleaning or repair process just by taking an unhinged fan off and setting it on the roof. Hinging eliminates the need to remove the fan as it can be tilted back to allow complete access to your system. Fans that are not hinged can become out of balance and begin to vibrate and make noise. Electrical wiring is more susceptible to damage in a fan that is not hinged.
