CFM output is dependent upon the horsepower of the motor:

• 2 HP = 9.1 CFM @ 125 PSI (Delivered CFM)
• 3 HP = 14 CFM @ 125 PSI (Delivered)
• 5 HP = 17.8 CFM @ 125 PSI (Delivered)

New flywheel size is 10.375" in diameter. If you have the larger 13.25" flywheel, determine the new pulley size for the motor by measuring the outside diameter (OD) of the existing pulley and multiply this number x .75 to come up with the correct new size.
Example:

4.25
x.75
3.1875" pulley (this can be rounded to the nearest pulley size, 3.25" or 3", for instance).
