Installation Considerations
CLEARANCE FROM SOLID OBSTRUCTIONS
For applications near solid obstructions, the HVLS fan must be installed at minimum distances.
Fans located near solid obstructions, such as walls racks or columns greater than 1FT wide, should
have a minimum distance of one half (1/2) fan diameter from the end of the blade.
Fans located above solid obstructions, such as racks, walls, etc. must have a minimum distance of
greater than or equal to 1/2 fan diameter above the obstruction. The obstruction below must also be
less than or equal to 1/4 fan diameter inside the fan blade arc. See
