AMCA Type A and B SRC also available upon request. Used when trace amounts of solids are in the fan airstream. Matching punched flanged fan outlet is required for mounting.ĪMCA Type C construction substitutes an aluminum inlet cone and adds a drive side aluminum buffing tube between the fan wheel, shaft and housing. Dampers have punched flanges on both ends to simplify fan and duct connections. Dampers for all fan classes have double thickness airfoil blades, and are available with parallel or opposed blade rotating louvres. However, they require substantially more horsepower at reduced air volume. Outlet Fan Dampers offer an economical alternative to IVCs. The compressed sheet seal mounted between steel plates is designed to reduce leakage through the drive side fan shaft opening. The IVC is suitable for manual or automatic operation. Ventilator vanes are mounted entirely within the fan inlet cone.
Adjustable guide fan vanes pre-spin the incoming air in the same rotation as the fan wheel to produce the desired volume of air at the exact pressure. The Inlet Volume Control (IVC) provides precise air control and more efficient performance at partial loads. Ventilator construction flexibility is one of the strengths of the fan, available in several AMCA arrangements, including 1, 3, 8and 9 to meet any installation requirement. Single-width fans are offered in Sizes 13 to 89, with pressures to 20" WG and volumes to 220,000 CFM. The Canada Blower single width airfoil fan is a rugged fan built to Canada Blower's industrial level of quality and long-term dependability. This fan has an enviable reputation for performance and reliability in a multitude of ventilating applications, including industrial supply or fume exhaust systems.
The heart of Canada Blower AF centrifugal fan is the airfoil wheel, the most efficient type for clean air applications. Precision balancing assures quieter vibration-free operation that adds to the overall reliability and performance of Canada Blower's airfoil fans. The fan's deep spun inlet and hyperbolic wheel cone plus generous fan housing proportions provide a smooth stable air flow over the entire performance range. Widely recognized for design efficiency and integrity, Canada Blower airfoil wheel has ideal characteristics for variable air volume systems. Wheels shall have precision spun, flat inlet cones to allow higher efficiencies over the performance range of the fan.
High efficiency, non-overloading airfoil blower wheels are provided on all sizes and fan arrangements.
