Backward Inclined Centrifugal Blowers
Every backward inclined centrifugal blower quote starts with the same 3 numbers. CFM, static pressure, and operating temperature.
You have those already.
The open question is which manufacturer line builds your selection in the right class and ships it inside your window.
We answer that across multiple lines. Flat blade or airfoil wheel. Direct drive or belt drive, Arrangement 1 through 10. Steel, stainless, or coated construction.
When one manufacturer’s line is backed up, we match the same selection from another.

Key Takeaways
Performance Ranges and Construction Options
| Specification | Available Range or Options |
|---|---|
| Airflow | 100 to 300,000 CFM |
| Static pressure | 0.2 to 40 in. wg |
| Wheel types | Flat single-thickness blade, hollow airfoil |
| Drive options | Direct drive and belt drive, Arrangements 1 through 10 |
| Construction class | AMCA Class I through IV |
| Spark resistance | AMCA Type A, B, and C construction |
| Materials | Steel, stainless steel, aluminum, coated and high temperature construction |
If your performance point falls outside these ranges, send it anyway. Custom selections are available across several lines.

Backward Inclined Fan Applications by Airstream
The airstream picks the wheel. Here is where a backward inclined centrifugal fan earns its spec, and what we select for each duty.
| Application | What We Spec |
|---|---|
| Dust collection, clean-air side | Flat blade wheels downstream of baghouse dust collectors, performance holds as filters load |
| Particulate-laden airstreams | Not this fan. We spec a radial blower for the dirty leg |
| Commercial HVAC, VAV, data centers | Airfoil wheels for peak efficiency, including plenum fans and arrays for air handlers |
| Cleanrooms and labs | Airfoil wheels in stainless, smooth flow through HEPA filtration |
| Food, chemical, and washdown areas | Stainless or coated construction rated for cleaning agents and moisture |
| Oven exhaust and process cooling | High temperature construction in standard duty ratings |
| Low pressure general ventilation | Often a forward curved fan wins on cost. We tell you when it does |
Send the application and the duty point. We match wheel type and construction to the airstream before quoting.
