Canada Blower airfoil fans are available standard in three construction classes to meet every application requirement. All fan classes feature heavy gauge housings and continuously welded scroll. Class II fan adds additional bracing in the larger sizes. Class III adds heavier shafts and bearings, and blower wheels reinforced with a stiffener ring to withstand higher pressure.

Canada Blower airfoil fan is a rugged multi-purpose centrifugal ventilator equipped with an airfoil wheel suited for supply and exhaust air and industrial applications. With energy efficient airfoil fan blades, Canada Blower airfoil fan provides reliable and quiet operation, even in mildly contaminated air. The fan is also suited for high temperature airstreams.

Airfoil fans are built under Canada Blower’s strict “Industrial Quality” standards, the same standards as those used on Canada Blower’s custom engineered fans, to assure exceptional performance and reliability. Canada Blower airfoil fans feature rugged heavy gauge fan housings and continuously welded scrolls. From material inspection to plasma cutting to assembly, every stepis governed by stringent quality procedures.

Canada Blower’s fan wheels feature airfoil blades continuously welded to a stream lined wheel cone and heavy steel backplate. The hollow ventilator blades have weep holes to prevent moisture build-up inside the fan blade. Airfoil wheels have true non-overloading horsepower characteristics, mechanical efficiency over 80% and a steep stable pressure curve, ideal for applications with pressure variations. Should actual system pressure reach 30% higher than the pressure anticipated, Canada Blower airfoil fan would still deliver 90% of the original design volume. Canada Blower airfoil is not only the most energy efficient wheel type, it provides the quietest operation. Fans are rated for temperatures to 800° when used with a shaft cooler and shaft seal. All of Canada Blower fans exceed AMCA performance standards.

INLET VOLUME CONTROL

When the fan is used for varying or partial load applications, the Inlet Volume Control (IVC) provides precise air control and more efficient fan operation. Adjustable guide vanes pre-spin the incoming air in the same rotation as the wheel to produce the desired volume of air at the exact pressure. Vanes are mounted entirely within the inlet cone. Automatic control is achieved by adding an electric or pneumatic actuator. The IVC is suitable for manual operation to 650°F and automatic operation to 350°F.

OUTLET DAMPERS

Fan dampers offer an economical alternative to IVCs. However, they require substantially more horsepower at reduced air volume. Dampers for all fan classes have double thickness airfoil blades, and are available with parallel or opposed blade rotating louvres. Dampers have punched flanges on both ends and are suitable for manual or automatic operation. A matching punched flanged outlet is required for mounting. Alternate construction is available for dirty or high temperature ventilation applications.
