FAN Law I.

The performances of fans of all types follow certain laws which are useful in predicting the effect upon performance of changes in the conditions of operation, the duty required of the installation, or the size of the equipment due to the space, power, or speed limitations. In the following law (Fan Law No. 1). Q = air volume and P = static, velocity, or total pressure.

Variation in Fan Speed: Constant Air Density – Constant System

Radial Blade Belt Drive Blower Table

(a) Q: Varies as fan speed.
(b) P: Varies as square of fan speed.
(c) Power: Varies as cube of fan speed.

Radial Blade Belt Drive Blower Table

Example: A certain fan delivers 12, 000 CFM at a static pressure of 1 in. of water when operating at a speed of 400 rpm and requires an input of 4 hp. If in the same installation 15,000 cfm are desired, what will be the speed, static pressure, and power?

Speed = 400 (15,000/12,000) = 500 rpm

Static pressure = 1(500/400) 2 = 1.56 in.

Power = 4 (500/400)3 = 7.81 hp

Fan Selection

When operating RPM for design performance is covered by more than one drive RPM range, use drive having top speed closest to operating RPM and select indicated model number.

Example – PWB-8

Design performance – 176 cfm @ 2.” S.P.

Operating speed – 3116 RPM @ .07 BHP

Select Model No. PWB8AA (2100/3142)

Improper selection – PWB8AB (2794/4200)

NOTE: First letter in model number suffix indicates motor horsepower. Second suffix letter indicates drive.
