Roof Ventilators manufactured by experts!

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

The 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 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 fan motor compartment, one-piece deep-spun venturi, built in grease trough and drain, aluminum non-overloading centrifugal wheel.

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. Fan 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 propeller  fan, removable access panel, rubber vibration isolators, and 1” aluminum washable filters.

Upblast Axial Power Roof Ventilators are general ventilation fan 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.

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.

Accessories: Prefabricated weather proof roof curbs, pitched to suit the roof slope are available in galvanized steel or aluminum. Automatic and Motor-Operated Backdraft Dampers provide weather protection and prevent backdraft. Aluminum hood, or aluminum hood/stack combination is available for corrosive environment. Side discharge is used for connection to supply / exhaust duct located outside on the roof. Safety Guard, Bird Screen, Insect Screen, or Filter Package are available upon request. Special protective coatings and alloys(aluminum, or stainless) are optional. Pre-wired and loose Safety Disconnect Switch, and Speed Controller are optional.

All models power roof ventilators bear the AMCA Seal.

What Kind of Industrial Fans in Canada are Better for Your Process and Plant ? To determine which industrial fans in Canada are best for your process and plant, you have to first consider the different types and their specific uses. With knowledge, you can then work with top industrial fan suppliers in Canada to ensure that you make the right fan selection.

Clean Air Axial Fans:

If you need spot cooling for internal components of machinery in areas with limited space, clean air axial fans are ideal. These fans are available in several sizes, and they also come in different voltages and cubic feet per minute ratings. Whether the spot cooling is for computers, industrial controllers, photocopy machines, or something else, these fans are the perfect solution.

These fans are designed in such a way that air is directed across an axis component while moving in a linear direction. Air is forced by the blades, which moves parallel to the shaft used for rotating the blades. Although there are multiple environments for clean air axial fans, they are most commonly found in manufacturing and engineering facilities.

Centrifugal Fans:

Industrial fan suppliers in Canada also offer centrifugal fans, which work differently from axial fans. Unlike axial fans that blow air parallel to the shaft, the air produced by centrifugal fans moves away from the fan blades. Based on the specific application, the blades of centrifugal fans can be straight or forward or backward curved. While blades curved backward tend to be more efficient, those with a forward curve are self-cleaning.

High Capacity Fans:

High-capacity fans are the preferred option to cool large spaces in plants, as some fans are capable of circulating air throughout an entire warehouse. Regardless of the environment, if you need a significant amount of air moved, this is the best solution. In addition to moving air, these higher capacity fans work to cool spaces down, making them ideal for congested plants.

The Bottom Line:

Regardless of the application, it is important to always choose fans made by top axial flow fans manufacturers. That way, you have the assurance that the fans are built correctly. Canada Blower, has been providing the industry with the best heating, air conditioning, and ventilation solutions for nearly 30 years..
