CA / CF: Steel Centrifugal Blowers
The CA/CF centrifugal blowers are designed for heavy duty supply, exhaust or return air applications. CA/CF blowers are available in AMCA standard discharges and rotations.
The CA blowers are standard with a steel backward inclined, airfoil wheel and are available in SWSI and DWDI configurations.
The CF blowers are standard with a steel backward inclined, flat blade wheel and are available in SWSI configurations.
- Continuously welded housing to ensure a leak-proof enclosure and all welded steel support structure for dependable, long lasting operational life.
- Lifting lugs are provided to assist in handling and positioning of the fan in the field.
- Outlet flanges are standard on all sizes
