forced ventilation fan

Forced ventilation fans generate positive pressure airflow to introduce fresh air into buildings, tunnels, or workspaces. They displace stagnant or polluted air, maintaining healthy indoor environments and meeting regulatory air-change requirements.

Available in axial and centrifugal designs, these fans deliver 5,000–150,000 CFM at static pressures up to 5 kPa. Robust casings and sealed motors allow operation in harsh or dusty settings.

Variable frequency drives (VFDs) enable demand-driven airflow, adjusting fan speed based on occupancy, gas sensors, or temperature, reducing energy consumption during low-demand periods.

Maintenance is simplified through split-casing for impeller access and external lubrication ports. Forced ventilation fans support applications from mine shaft intake to industrial process makeup air.
