Fan Efficiency for Dust Collectors

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.

AirPro built the following fan for a Wisconsin company that dries potatoes for use in animal feed. The exhaust fan is installed at the end of the drying process. A gradual build-up of particulate on the wheel resulted in excessive fan vibration levels. AirPro field service technicians were hired to balance the fan, restoring it to smooth operation.
