Primary Industries for Dust Collection
The preliminary indicator of the application environment is the industry of operation. Many industries use dust collector fans in their systems, including:
- Industrial Processing
- Food & Beverage Manufacturing
- Agricultural/Grain Processing
- Metal Fabrication & Machining
- Mining & Mineral Processing
- Pharmaceutical Manufacturing
- Lumber and Woodshop
The industry application is a factor in determining what type of system and dust collector fan to select. For example, grain processing applications require a baghouse dust collector, which in turn calls for a high CFM industrial fan to enable a higher volume of airflow through the filter. Most industries use smaller, more efficient cartridge collectors, which allow for other fan options based on what kind of material the system is processing.
Dust Collector Fan Selection & Specification
There are several things to consider when choosing the most effective fan, including the level of dust loading, clean-side or dirty-side, airflow, and static pressure.
Common Clean Air Dust Collector Fan Types
Most dust collector fans are on the clean side. In this case, they only need to move clean air, as the systems will remove the dust and contaminants before the air goes through the fan.
Fan Types for Dust-Laden Air
Other fans actually need to handle the contaminants. Our self-cleaning radial tipped fan with curved radial blades and industrial exhausters with partially backward inclined blades are ideal for handling contaminants without material build-up in the fan.
Dust Collector Fan Arrangements
Fan Arrangements specify how the motors mount to and drive the fans. Dust collector fans can use both direct drive and belt drive options. Smaller cartridge collectors often use direct drive “top mount” fans where the fans mount directly to the top of the collector. Larger units and baghouse collectors will use ground-mounted fans installed on foundations separate from the collectors.
Here are some basic guidelines for dust collector fan arrangements:
Arrangement 1: This direct-drive motor with a unitary base will tend to be best in systems requiring 50-200 HP
Arrangement 4: This is a ground-mounted direct-drive motor with a pedestal base for a larger system.
Arrangement 4V: A direct-drive motor for most small fans up to about 50 HP, where the fan will mount directly on top of the dust collector.
Arrangement 8: This is a direct-drive motor for large fans >200 HP
Arrangement 9: A belt-driven motor option that mounts to the side of the fan pedestal rather than a unitary base to save space.
Dust Collector Fan Accessories & Design
Dust collector fans often require accessory items and customization for optimal performance and maintenance.
Accessory & Design Considerations
Food Grade Considerations
- 304 or 316 Stainless Steel materials of construction
- Glass Bead Blasting to SSPC-SP10 (the highest weld rating) or chemical treatment for removal of weld discoloration
- 32RA Polishing of the Welds and stainless steel materials for a uniform 32 micro-inch finish
- A Simple Epoxy finish for non-stainless steel components
- Clean-in-Place (CIP) Nozzles inside the fan housing along with a drain system at the bottom of the housing for cleaning access during use
- Stainless Steel Washdown Duty Motor with a Stainless Steel shaft for those requiring all parts in contact with the product be food grade
- Ferrule (Sanitary) Drain, Cap & Gasket with no threads
- Teflon Fan Seals and Housing Gaskets to provide food-grade sealing capabilities.
- Flange, Slip inlet & Slip Outlet allows a flexible boot to connect the fan to the ductwork
