Industrial backward inclined (BI) fan blower

Chicago Blower SQB Type "B" fan wheel has backward inclined blades designed to handle corrosive or dusty airstreams. Typical fan applications include: oven circulating fans, dust collector exhaust fans, fume exhaust ventilators and emissions control fan systems. Since the ventilator blades are solid steel, the "B" wheel is ideal for custom applied corrosion resistent coatings. The SQB fan is also suited for high temperature gasses and air to 650°. For greater safety in explosive environments, spark resistant ventilator construction is offered. The versatile SQB blower is furnished in 14 sizes in Arrangements 1, 9 or 9H and in three classes of construction.

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.


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.


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.


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".

Chicago Blower's SQB blower is regarded as a high performance, trouble free fan proven in a myriad of industrial air moving applications. With its backward inclined wheel blades and square fan housing design, the SQB ventilator is efficient, economical and versatile. It is also quickly available through Chicago's Stock Fan program. "Packaged" fans, those furnished with motor, V-belt drive, belt guard and other options, are factory aligned, run tested and shipped ready to install. By eliminating jobsite assembly, the packaged SQB fan can substantially reduce overall installation cost.


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.


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.


Canada Blower 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.

Canada Blower centrifugal Radial Fans are blowers whose primary function is to enable movement of large flow of gas or air for providing process relief in industrial units. These Canada Blower fans are specifically designed and built to operate at high or low temperatures, corrosive gases, acidic fumes etc., and are capable to handle different types of gases in any process plants. These fans find applications in several process plants as below:

Design 64 Packaged Backward Inclined Fan: Canada Blower BI fan is the right choice for your requirements, designed to increase the stable operating range by over 20 %. This enables you to offer a wider performance range and thereby eliminate fan sizes. Canada Blower BI fan is offered in 12 sizes from 12 to 36 and in standard fan widths of 100 %, 75 % and 50 %. With the availability of three motor RPMs, a PBI fan will meet all your necessary performance and physical specifications. Developed initially for the dust collector industry, Canada Blower’s new Packaged Backward Inclined (PBI) fan is also ideal for an expanding range of applications, such as laser cutters, air filtration, and pneumatic conveying, up to 150°F. Canada Blower BI fan is also the perfect replacement for older, less reliable fans.  Since Canada Blower’s BI is a direct drive fan, initial cost is
less and belt drive problems are eliminated – periodic belt adjustments, belt squeal, horsepower guesswork. It all adds up to a more energy efficient, more dependable fan. In fact, Canada Blower’s run tested PBI fan’s most important benefit is the reliability we add to your product.

New High Performance Wheel: Canada Blower has developed a new wheel for the BI fan. The blower wheel uses heavy backward inclined steel blades for maximum performance in hostile environments. The BI blower wheel, coupled with the streamlined inlet, virtually eliminates vibration and reduces noise levels dramatically.

Rugged Housing: Heavy gauge steel and added drive side support gussets contribute to extended vibration-free operation, critical for any installation. Continuous welding of housing assures air tight seams. The fan’s support gussets have four built-in lifting eyes for easy balanced lifting.

Punched Flanged Outlet / Inlet: Equipped as standard, both the inlet and outlet are flanged and punched for easier installation. The outlet flange allows for bolting of ductwork, dampers, blower silencers or screens directly to the fan. An optional universal inlet flange that bolts to the equipment has a larger opening and larger diameter bolt circle.

C-Face Motor Mount: Allows C-face motors to mount directly to the fan housing, creating an airtight fit-up with no shaft seal. As the motor weight is also centered over the blower wheel, stability is improved when running in the vertical fan position.

Canada Blower fans withstands Adverse Environments: Since some dust collector fans are installed outside the facility and subject to year-round environments, the C-face motor is bolted directly to the housing and caulked with adhesive sealant to provide weather-proofing and keep water out.

Square: Canada Blower BI fan is also available in the square housing. Housings have welded air-tight seams with all edges flanged for exceptional rigidity, thereby allowing the fan to be installed in any of four discharge positions.

Canada Blower fan outlet dampers are often selected as a low cost option for varying the airflow. Dampers have punched flanges on both ends to simplify fan and duct connections. Opposed acting blades are standard with parallel blades available.
