CFM Axial Airfoil Impellers

Description

Continental Fan’s CFM axial airfoil impellers are the ideal OEM (original equipment manufactures) components for ventilation applications. HVAC systems, cabinet cooling fans, mobile HVAC unites, cooling towers, tunnel ventilation, process cooling, bulk drying, and radiator cooling systems are just a few applications where these impellers are applied. These superior impellers are utilized in some of our industrial fans, and they are available as replacement impellers in industrial application.

Designed using the latest computer aided technology, Continental Fan’s axial airfoil impellers incorporate an advanced airfoil blade design that is exceptionally quiet and efficient. Integrating innovative pressure cast aluminum hubs and adjustable pitch blades, these axial airfoil impellers deliver an impressive array of airflow performance. Custom diameters available from 12″ through 79″, and airflow capacities range to 200,000 cfm.
