- CFM = (fpm * area), where fpm is the feet per minute.
- To find the cubic feet per minute, substitute the FPM value with the area after the area is squared.
How much HP do I need in a shop vac?
To get excellent suction power, have a higher HP. If you have already vacuuming stuff, any 1-2 hp vac will do for removing dirt, san, and all types of debris. You are recommended to go for 4-5 hp.

Peak HP of most machines only occurs for a short period of time. Most circuit breakers can hold several times their handle rating, up to about 45 amps in this case, to account for starting current of motors and should easily handle the 5 HP, 33 amp peak of your vacuum.
How do you increase vacuum suction?
One of the easiest ways to increase vacuum cleaner suction is to replace or empty the dust collection bag. As the collection bag fills, less air is able to pass through, which reduces suction power and pressure. By emptying or replacing this bag, users will enjoy a natural improvement in suction power.
What does CFM mean on a vacuum pump?
Capacities expressed in CFM or SCFM (standard cubic feet per minute) can be very misleading because we have to take into consideration the volumetric efficiency of the pump at a specific vacuum level (see example below).

What is kPa suction?
It’s typically measured in kPa (kilopascal). Without going into details, Pascal is the measurement of pressure and the kPa unit of a vacuum cleaner is the difference between the normal atmospheric pressure and the pressure inside the vacuum cleaner hose. More the difference, higher the suction pressure.
How do you calculate CFM for a machine?
Start with the total volume of air (in cubic feet), divide by the exchange rate (how quickly you want to replace the air), and the result is the total CFM you need for your system.
How do you calculate airflow?
Calculate the duct air flow, or “q,” using the formula: q = v x A. For example, if v is 15 m/s and the A is 8 square meters, q is 120 cubic meters per second or 120 m^3/s.
How do you calculate centrifugal blower CFM?
Define the terms in the general centrifugal fan formula and rearrange them to use the formula to solve for the higher air flow: CFM 1/CFM 2 = RPM 1/RPM 2 x (D1/D2)^3 (cubed). The (D1/D2)^3 is 1, since the impeller diameter stays the same, so CFM 2 = CFM 1 x (RPM 2/RPM 1).
