Baghouse Fan Selection Guide
A baghouse fan should be selected according to airflow, total system resistance, filter pressure drop, duct layout, dust characteristics, temperature, material, motor power, and whether the fan is installed before or after the baghouse. Correct selection is essential for stable dust collection performance.
What a Baghouse Fan Does
The fan creates airflow through dust hoods, ductwork, the bag filter, and exhaust stack. If the fan pressure is too low, dust capture may be poor. If airflow is too high, filter bags may wear faster and energy use may increase.
Key Data Needed
- Required airflow
- Filter pressure drop
- Duct resistance
- Dust concentration
- Dust abrasiveness
- Temperature and humidity
- Explosion-proof requirement
- Material or coating requirement
Fan Position
The fan can be placed before or after the baghouse depending on system design. A clean-side fan may reduce fan wear, while a dirty-side fan may be required in some process layouts. The arrangement should be reviewed by the dust collection system designer.

FAQ
What causes poor baghouse suction?
Possible causes include insufficient fan pressure, clogged filters, duct leakage, wrong duct design, or incorrect fan speed.
Can a baghouse fan be wear-resistant?
Yes. Wear-resistant impeller design or material treatment can be selected for abrasive dust.
