Centrifugal Fans

Roof Ventilators manufactured by Canada Blower

Centrifugal Downblast Domed Canada Blower Power Roof Ventilators are ideal for ventilation of commercial and institutional buildings. Fan features spun aluminum weather resistant housing with isolated fan-cooled motor-drive compartment. Self aligning regreasable ball bearings are standard.

Canada Blower low silhouette spun aluminum centrifugal power roof ventilators, and louvered aluminum power roof ventilators are created for low cost general exhaust for a wide range of commercial uses. Both designs utilize standard variable pitch V-belt drive, adjustable motor support base, and non-overloading aluminum wheel, or axial prop.

Centrifugal Canada Blower Upblast Power Roof ventilators are designed to exhaust grease-laden air (UL 762) and for general ventilation applications (UL 705). Construction features sealed spun aluminum positive ventilation motor compartment, one-piece deep-spun venturi, built in grease trough and drain, aluminum non-overloading centrifugal wheel.

Canada Blower Filtered Air Supply Roof Ventilators are designed to supply untempered make-up air to environments, where vapors, mist, gases, or odors are removed by an exhaust system. Applications include garages, foundries, plants, kitchens, athletic clubs,etc. Fan features weather hood (galvanized, or epoxy coated) with insulation for moisture barrier, forward curved centrifugal blower, or axial prop fan, removable access panel, rubber vibration isolators, and 1” aluminum washable filters.

Upblast Canada Blower Axial Power Roof Ventilators are general ventilation units for handling of large volumes of air. A distinctive feature of the fan is leak-proof butterfly damper with watertight sealed base. Wheel again is axial die formed prop, or cast aluminum adjustable pitch airfoil propeller.

Canada Blower Axial Hooded Power Roof Ventilators are high capacity exhaust fans, designed for removal of large volumes of air in warehouses, factories and mills. Fan features weather hood, rain channels and watertight sealed base with spun venturi. Wheel is either die formed propeller, or cast aluminum adj. pitch propeller. Bird screens, Insect screens and removable filter packages are optional.


Centrifugal roof exhaust fans are designed for roof mounted exhaust of clean air in applications where it is desirable to move the exhausted air up and away from the building, and where re-entry into the building supply air is possible.

Centrifugal roof ventilators are similar to the DCRU / BCRU fans, but are specifically designed for exhausting grease-laden air from kitchens, restaurants, cooking and dishwasher hoods. Canada Blower also offers grease collection systems for kitchen and restaurant use.

Pressure Blower

Canada Blower Plug Fans use an unhoused backward inclined wheel with operating efficiencies comparable to housed fan equipment. Plug Fans are available in two wheel designs: AcoustaFoil - an airfoil design providing aerodynamic superiority for clean-air applications; and backward-inclined flat blades for rugged utility. Plug Fans are avail-able for insulated or uninsulated wall mounting with temperatures to 1300°F., capacities to 74,000 CFM, and static pressures to 14” WG.

When applied to ovens, dryers, air conditioners, or built-up process systems, these predetermined combinations of housings, shafts, bearings, and forward-curve wheels provide flexibility of performance and bearings centers, and overall reduction of unit size compared to other air-moving alternatives. Eight sizes of Air Kits are available in single-fan or two- fan assemblies, with capacities to 60,000 CFM, static pressures to 6” WG, and temperatures to 1000°F.

The same fan housings, wheels, and inlet cones used in AcoustaFoil and PLR Fans are available to original equipment manufacturers. These components offer a variety of configurations limited only by the needs of the system and good engineering practice. Class I, II, III, or IV construction. Canada Blower Airfoil and Backward Inclined wheels with diameters from 12” to 73” encompass a full range of airflow and pressure capabilities.
