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.
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.

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:
Canada Blower Company is a supplier of Industrial and Commercial fans
and blowers of all types.

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.
