Not all Fans are Created Equal
Life Safety Professionals work hard to develop and enforce building codes to eliminate or reduce potential threats. Nothing can be more frustrating and sometimes more costly than not having the correct product to comply with the building code for your project.


Wood is a Combustible Material
When you’re building a multi family residential project using wood frame construction you’ll need to comply with stringent requirements to prevent the spread of fire. These are likely to include the use of fire rated products for ceiling penetrations such as bathroom exhaust fans. Air King Fire Rated Fans have been tested and are UL Listed for use in wood frame construction and have been successfully tested by UL in more truss designs than any major manufacturer. You will see competitor certifications that will say “For use in any fire resistive Floor or Roof-Ceiling assembly”. That does not necessarily mean UL listed for wood frame construction. Wood construction is NOT fire resistive; wood is a combustible material that fire fighters usually consider fuel. The UL requirement for Listing in this case requires mounting and testing of the fan in each approved truss design above an actual fire. You know you have the right product for the application when the manufacturer provides the truss design numbers for which the product was tested. No design number - Not UL Listed for wood frame construction. Air King Fire Rated Fans on the other hand are currently UL Listed for the greatest number of wood frame truss designs. Be sure you have the right product and save yourself a lot of time and trouble by starting with Air King.
