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 to calculate the required airflow per fan.
To calculate the CFM required to adequately ventilate an area, we divide the room volume by the appropriate 鈥淢inutes per Change鈥� 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.
Square base dimension on power roof ventilators. Square fan panel dimension on sidewall propeller fans.
Transmission type of the ventilator (belt drive or direct drive).
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.
Describes the fans or ventilators a particular accessory can be used with.
The "ACTUAL" damper width and height. Dampers are undersized to allow them to be mounted into the duct work/wall opening.
This dimension describes the discharge diameter of a given product.
This is a feature which protects the motor from overheating and thus prolongs service life of the machine. In the event that the motor approaches overheating the thermal protection cuts power and only returns it after a cooling period.
