Canada Blower Backward Inclined Fan is a rugged multi-purpose centrifugal fan equipped with Backward Inclined wheels suited for harsh duty applications. With heavier fan blades to resist erosion and corrosion, Canada Blower Backward Inclined Fan provides reliable operation in contaminated air with minimal maintenance. Similar BI wheels are used in Canada Blower's SQB fans for alternate duty applications. For clean airstreams, Canada Blower airfoil bladed fans are recommended. Canada Blower's backward inclined fan blades are designed to handle corrosive or dusty airstreams. Typical applications include oven circulators, dust collectors, fume exhausters and emission control systems. Canada Blower Backward Inclined Fan is also suited for high 800°F. The solid steel blades are ideal for custom applied corrosion resistant coatings ventilating.com fanblower.com highpressureblower.net industrialblowerfan.com industrialfanblower.net industrialfanblower.com pressureblower.net northernindustrialsupplycompany.com industrialpressureblower.com tenderall.com chicagoblowercanada.com cbblower.com buffaloblower.com buffalofan.com nis-co.com canadianblower.com olegsystems.com canadablower.com abbblower.com acmefan.net industrialblower.net fansandblowers.net americanblower.net barryfan.com cincinnatifan.net canadafans.com barryfan.net pennbarry.net pennfan.net tcffan.com.

CLASS II FAN

Meets specifications for most general industrial ventilation applications. Features heavy gauge fan housings with continuously welded fan scroll. Sizes 49 to 73 for pressures through 12". Refer to Canada Blower SQB fan for smaller sizes.

CLASS III FAN

Same rugged fan construction as Class II with additional housing bracing and fan wheels reinforced with a stiffener ring. Fans are equipped with heavier fan shafts and bearings. Sizes 49 to 60 for pressures through 14". Refer to Canada Blower SQB for smaller sizes.

CLASS IV FAN

Still heavier gauge housings, shafts, bearings and two blower wheel stiffener rings. Class IV Design Canada Blower fans are practical alternatives for installations where less efficient radial blades were considered necessary. Sizes 22 to 49 fans for pressures through 24".

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 fan wheel to produce the desired volume of air at the exact pressure. Vanes aremounted entirely within the fan 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. Fan dampers for all fan classes have double thickness airfoil blades, and are available with parallel or opposed blade rotating louvres. Fan dampers have punched flanges on both ends and are suitable for manual or automatic operation. A matching punched fan flanged outlet is required for mounting. Alternate damper construction is available for dirty or high temperature ventilation applications.

SPARK RESISTANT FAN CONSTRUCTION

AMCA Type C spark resistant construction substitutes an aluminum fan inlet cone and adds a drive side aluminum buffing tube between the wheel, shaft and fan housing. Available with all fan classes and sizes, arrangement 1 and 9, Maximum temperature is 600°F. Not available when the fan is equipped with an IVC. Requires customer to electrically ground fan.
