Calculate Air Exchange (CFM)
Use the calculator to determine the Air Exchange (CFM) required to adequately ventilate an area.Enter information into the fields below in order to calculate the CFM (per fan).
To calculate the CFM required to adequately ventilate an area, we divide the room volume by the appropriate "Minutes per Change" value.
[CFM] = [Room Volume] / [Min./Chg.]
Airflow (CFM) per Fan

Starred items represent required fields.
Calculate Static Pressure (SP)
Use the calculator to determine the amount of static pressure the fan must overcome.The pressure generated by fans in ductwork is typically very small. An accurate measurement of static presure is critical to proper fan selection however. Static pressure in fan systems is typically less than 2" SP, or 0.072 Psi.
The amount of static pressure that the fan must overcome depends on the air velocity in the ductwork, the number of duct turns (and other resistive elements), and the duct length. For properly designed systems with sufficient make-up air, the guidelines in the table below can be used for estimating static pressure.
Static pressure
* Starred items represent required fields.
Static Pressure Guidelines
Non-Ducted 0.05" to 0.20"
Ducted 0.20" to 0.40" per 100 feet of duct (assuming duct air velocity falls within 1,000 to 1,800 feet per minute)
Fittings 0.08" per fitting (elbow, register, grill, damper, louver, duct turn, etc.)
Kitchen Hood Exhaust 0.625" to 1.50"
Important: Static pressure requirements are significantly affected by the amount of make-up air supplied to an area. Insufficient make-up air will increase static pressure and reduce the amount of air that will be exhausted. Remember, for each cubic foot of air exhausted, one cubic foot of air must be supplied.

Applications/uses for a particular fan or ventilator.
Refers to the location where a fan or ventilator can be mounted.
Transmission type of the ventilator (belt drive or direct drive).
Indicates the space relationships of windings and changing values of the recurring cycles of AC voltages and currents. The most common power supplies are either single- or three-phase.
The force that causes a current to flow in an electrical circuit. The voltage of a motor is usually determined by the supply to which it is attached. NEMA requires that motor be able to carry its rated horsepower at nameplate voltage plus or minus 1% al
The power required to drive an air moving device. Horsepower required varies with system conditions.
Describes the size (width x height) of the opening where air is drawn into a ventilator.
This dimension refers to the size of the discharge (where air leaves the ventilator) on a particular unit.
Refers to the orientation in which a product can be mounted.
