Squirrel Cage Blower Wheel with Forward Curved Blades
What some may call a squirrel cage blower wheel is also what we call a forward-curved centrifugal fan. Either way, it gets its name based on the many small blades that make up this fan wheel causing it to look like a squirrel cage or hamster wheel! The result is a blower that moves higher volumes of air and gasses at low pressures for various industrial operations.
Industrial fans have a special job to do when used in a dust collection application. They need to get the dust-laden air past the filters in the dust collector baghouse. The system pressure varies based on how “dirty” the filters are, and you can adjust the fan speed accordingly. Properly adjusting the speed can reduce your overall power consumption, but that depends on whether or not you place the pressure gauge in the right spot.
Dilution air (air that combines with flue gas) is present in power plants, as well as boiler systems, cooling systems, and other industrial systems that produce dirty air. Each of these requires a dilution air fan to assist in removing the pollutants from the flue gas to clear the air for breathing.
