Canada Blower Forward Curved Fans
The impeller of the fan is fitted with blades curved forward in the
direction of wheel rotation. Because of this forward curve, the fans
are capable of accelerating air to a high velocity while rotating at a
lower speed. They are less efficient than airfoil and backward inclined
fans and have limited usage in industrial applications. Forward curved
fans are ideal for low pressure applications such as domestic furnaces,
ventilation and air conditioning systems.
Backward Inclined Fans
These are radial fans with backward curved blades that are flat and of
single thickness. They can handle relatively medium to high volumes of
airflow at high static pressures. These fans are typically known as
“non-overloading” because the impeller has non-overloading
characteristic and the changes in static pressure do not overload the
motor. Backward inclined fans are slightly less efficient than airfoil
fans and are used in high volume applications such as for heating,
ventilation and air conditioning systems.
Canada Blower Double Inlet Centrifugal Fans
They are heavy duty fans and are customised for various industrial
processes. They serve the purpose of providing large airflow in the
industrial processes. It has two separate inlets and one common outlet.
Fan inlet boxes are fitted with dampers to control the airflow.
Canada Blower Multistage Centrifugal Fans
Many industries have requirement of high pressure. The output is
achieved by using two centrifugal fans in cascade. They have two
impellers fitted on a single shaft. The airflow from first impeller is
magnified by the second impeller. Chemical industry utilises multistage
centrifugal fans for evaporation of chemical substances. It also finds
application in other industries which require high pressures like
cement, power plant and wood industry.
Canada Blower Radial Blade Fans
The impeller of radial blade fans consists of multiple equally spaced
flat blades that are radial to the fan shaft. The wheel is paddle type
and may or may not contain side rims. They are less efficient than
other centrifugal fan types. They produce medium to high pressure and
are well suited for material handling and in some moderate pressure
Canada Blower Airfoil Blade Fans
The blades of these fans contain airfoil blade shape which is hollow
and backward-inclined. Their speciality is that they can handle large
volume of air at low to moderate static pressure. They produce optimum
efficiency and can handle large volumes of air in industrial
applications, ventilation, air conditioning etc.
Canada Blower Radial Tip Fans
Canada Blower Tubeaxial roof ventilators are built of heavy gauge steel
for rugged industrial service where the fan assembly must be located
above the roof. Ventilators are designed to operate reliably in hostile
environments where high temperatures or contaminated air are present.
The fan motor, belts and bearings are isolated from the air stream. THe
JTBC PRVs are constructed of extra heavy gauge steel, up to 1/4" plate.
The fan shaft is supported by two pillow-block ball bearings that are
mounted in the enclosed tube to provide years of service under harsh
conditions, they are suitable for operation to 250 F.
These Power Roof Ventilators can be easily connected to duct work when
exhausting from a ducted system with the use of the optional duct
Canada Blower tubeaxial roof exhausters are available in wide range of
sizes and capacities: with blade diameters from 18" to 84" and
capacities ranging from 1000 CFM to appr. 100,000 CFM. Direct driven
fan models for low maintenance are available too.
