A bag filter fan is integral to baghouse dust collectors, drawing air through fabric filter bags that trap particulates while allowing clean air to pass. It supports dust control in heavy industries.
These centrifugal fans handle 10,000–150,000 CFM at pressures up to 7 kPa. Impellers are abrasion-resistant, and casings use carbon or stainless steel.
Pulse-jet cleaning systems and differential-pressure sensors enable automated filter regeneration, maintaining airflow without shutdown.
Maintenance is facilitated by split-casing access, external lubrication ports, and vibration monitoring. Bag filter fans ensure compliance with particulate emission standards across cement, steel, and power plants.
