SPRINKLER SYSTEMS AND FAN PLACEMENT
In any installation where fire sprinklers are in place, the fan should not interfere with their correct operation. Fans should be
located fewer than 3 feet below a sprinkler and placed central to each sprinkler quadrant. Our industrial control panel can be
connected to a fire relay system, which, in an emergency, will stop fans in case of fire.
Prior to installing fans, review all codes applicable to sprinkler systems and fans to ensure code compliance and refer to NFPA
13 Standard from the National Fire Prevention Association.
Please call our Technical Department for guidance at 1-844-593-FANS (3267). However, it is your sole responsibility to see that the
installation is completed to code and that it is correct.
OTHER INFORMATION ON PLACEMENT AND SPACING
If possible, avoid mounting fans directly below lights or skylights to avoid any strobe effect caused by moving airfoils. Note,
a large fan, 20 to 24 feet in diameter, performs best at 20 to 30 feet above the floor, but acceptable performance has been
demonstrated as low as 10 feet and as high as 50 feet.
If the building has a mezzanine, fans should be mounted so a person cannot reach a fan in any way from the upper level/
deck. Make certain that fans are positioned so that the airfoil tips are at least 3 feet away from any area where a person may
be able to extend outward to reach them.
Fans should not be located directly beneath any air discharge. This includes air conditioning units and evaporative coolers.
Such equipment can be used effectively in conjunction with HVLS fans, but the discharge must be located outside of the
swept area of the fan.
