The goal of this diagram is to determine the proper extension length to maintain a minimum blade clearance of 15% of the fan’s 

diameter. The extension lengths above are minimum recommendations only, based solely on roof pitch and fan diameter. Other factors 

must be evaluated when determining extension requirements. In addition, OSHA requirements state that the fan blades must be a 

minimum of 10 feet (3.05 meters) above the floor. Contact our technical department for assistance with fan placement and extension 

selection (technical support contact information can be found on page 39). 


I-BEAM MOUNT 

For installations with I-beams use MacroAir I-Beam 

Kit (PN 60-50106-00). To properly install mount be 

sure to use hang mount along slope of the roof. 

I-Beam Assembly 

Exploded View 

For ease of installation the Unistrut for our 

I-beam mount can be installed in two differant 

configurations. Refer to images above for examples. 


GLULAM MOUNT 

Installation on Glulam beams will use 

MacroAir Glulam Mounting Kit (PN 60-50108- 

00). Installing the mount alonge the slope of 

the roof will allow the proper leveling of the 

fan. Through bolts should be used to attach 

the mount to the glulam beam. DO NOT USE 

SCREWS. 

Glulam Installation utilizes 

unistrut in conjunction with our 

glulam bracket and through 

bolts for installations containing 

glulam beams.
