forced exhaust fan

Forced exhaust fans are axial or centrifugal blowers designed to push exhaust air out of spaces by generating positive pressure. They remove smoke, fumes, heat, and pollutants, making way for fresh intake air through designed inlets.

With flow capacities from 5,000 to 100,000 CFM and static pressures up to 5 kPa, these fans are used in tunnels, industrial plants, and confined spaces. Robust housings and abrasion-resistant impellers ensure durability.

Integration with variable frequency drives (VFDs) and sensor feedback—monitoring temperature, gas concentration, and airflow—enables on-demand exhaust, reducing energy use and noise levels during low-demand periods.

Maintenance features such as split-casing for impeller access and external lubrication ports simplify service. Forced exhaust fans enhance safety and air quality in demanding environments.
