Step 1: Select the proper size fan: Multiply the
length, width, and height of the room to determine
the cubic volume of the space. Divide the cubic volume
by 7.5 This is the CFM capacity of the fan required.
Large bathrooms may require 2 fans.
Check the dimensions of the fan and
verify it will fit in the space selected.
After measuring the room dimensions,
multiply the room height, width, and
length to determine the volume of the
room in cubic feet.
Step 2: Select the fan location:
Placing the fan near the source of
moisture or odor is ideal. If you are
placing the fan close to the shower,
please use a GFCI circuit breaker on
the fan circuit for added safety.
