chemical ventilation fan

Chemical ventilation fans remove harmful vapors, fumes, and dust from chemical processing rooms and exhaust ducts. They feature FRP or stainless-steel construction and spark-resistant impellers for safety.

Axial and centrifugal variants handle 2,000–150,000 CFM at pressures up to 8 kPa. Explosion-proof motors and sealed bearings ensure reliable operation.

Variable frequency drives (VFDs) provide demand-driven extraction, adjusting flow based on gas sensor feedback to maintain safe air quality while conserving energy.

Maintenance is facilitated by split-casing impeller access, external grease fittings, and remote condition monitoring. Chemical ventilation fans are essential for safe, compliant air handling in corrosive environments.
