Centrifugal Dust Collector Fan - Combifab Series
The Combifab Series of fans are heavy duty centrifugal fans with three different fan wheel designs and four housing and drive configurations to meet the application requirements. AirCare stocks a large inventory of fans for immediate delivery so please call to check availability. Also, we carry used inventory for those on a budget.
When it is time to replace an existing fan or install a new system, a more efficient solution for the fan design may be a direct driven configuration with a Variable Frequency Drive - VFD on the fan motor in lieu of a belt driven configuration. Belt drive losses require 2-5% of more energy than a Direct Drive - VFD arrangement. Furthermore, with this type of configuration, the fan performance can be modified manually for the VFD control interface and a PID Control Loop and Autogates can be installed to minimize energy consumption. See the System Optimization Section for more details.
Features and Benefits
- Three Style of Wheels for Clean Air, Dry Dust and Material Handling Applications
Bladed Impellers - The Heart of the System
