Duct Fans

Duct fans are engineered to move or exhaust air through HVAC ducts, ventilation systems or smoke-extraction setups, delivering efficient airflow while overcoming duct static resistance.

Available in inline or plenum styles, these fans offer quiet operation, variable-speed compatibility and rugged construction to support industrial, commercial or institutional installations.
