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.

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".

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.

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

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.

Dust collectors and filtration media provide effective solutions for managing a variety of industrial dust issues including toxic, explosive and potent compounds. These cartrideg dust collectors are:

* Powered by nanofiber filtration technology;
* Provide cleaner air with up to 25% more filtration capacity than other collectors;
* Dust collection filters last up to two times longer;
* Provide significant cost savings and optimal service.

Industrial dust collection systems and products remove industrial contaminants from polluted air, and where feasible, return clean air back into the environment. Benefits of industrial dust collection may include:

- Employees are protected from the harmful effects of pollution with an effective industrial dust collection system.
- Industrial dust collection keeps facilities compliant with health and air emission regulations.
- Use of industrial dust collection systems protects the environment from pollutants from manufacturing processes.
