Furnace Fan Cfm. In this video we learn how to calculate the pulley diameters for motors and fans as well as their rpm and what the air flow rate will be. To convert cfh to cfm, we need to divide that 5,120 ft 3 by 60 (because 1 hour = 60 minutes).
4.5 out of 5 stars 54. For example, if you are checking a 3 ton system, the air flow required is between 1050 and 1200 cfm. More buying choices $88.20 (16 new offers) rectangular permanent split capacitor blower | replaces:

Stage may be used to control this furnace. It is then divided by the volume of the room you wish to measure (in cubic feet): A cfm of 75 is the minimum number to make a fan efficient.
