What is a Fire Rated
Exhaust Fan?
The Air King Fire Rated Exhaust Fan Series consists of
a three part system designed to meet the NFPA’s
(National Fire Protection Association) Standard 90A.
The unit consists of a Housing, a Ceiling Radiation
Damper, and the Motor/Blade/Grill. When all three of
these parts are used together they create a Fire Rated
Exhaust Fan.
What does a Fire
Rated Exhaust Fan Do?
The Fire Rated Exhaust Fan Series is designed to
automatically shut off and seal the duct from the rest
of the dwelling once the temperature of air passing
through the damper exceeds that of the fusible link.
This prevents the spread of smoke or fire through the
ducting system to the other rooms or dwellings.
Why do I need a Fire
Rated Exhaust Fan?
Your local code will dictate if and what type of Fire
Rated Exhaust Fan you will need. Generally any time
a common duct is used in a multi-dwelling situation,
a Fire Rated Exhaust Fan will be required to prevent
fire from using the common ducting to spread from
one dwelling to the next. This is usually true in
commercial and multi-family housing constructions.
