Webdrive is that it is capable of adjusting the fan rpm, which enables the fan to move more air if necessary. Motor pulleys are adjusted by loosening the set screw and turning the top half of the pulley (see illustrations at right). This causes the pulley diameter to change, which results in changing the fan rpm. Opening the pulley decreases fan rpm. WebFan curves are simply graphs showing fan performance, normally with air volume on the horizontal “x” axis, and pressure on the vertical “y” axis. To obtain a fan curve the fan is placed in a test rig in which air pressure and …
