Tips for installing a ventilation fan
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. Click
here for product selection guide.
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
