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.

SQA fans have been selected for well over 100,000 industrial and commercial installations worldwide. The SQA fans are known for their exceptional durability and efficiency, and are continually updated and expanded to meet today’s requirements and tomorrow’s visions. This versatile innovative design packs maximum performance into a minimum footprint.

Canada Blower Duct Fans are designed forlow pressure ventilation and industrial process applications. Uses include heat, smoke and fume removal; process drying with ambient or pre-heated air; comfort and process cooling and general ventilation. All applications can be handled in either supply or exhaust configurations. Numerous modifications and fan accessories make the Vaneaxial Fan suitable for a wide range of systems.

In applications where equipment space is at a premium, the compact flow-through design of the Duct Fan can reduce system space requirements by more than 50% over conventional centrifugal fans. The straight, in-line design eliminates the need for costly, space-consuming transitions, elbows and inlet boxes.

Canada Blower Duct Fans feature steel wheels in all sizes. Each wheel is designed to maximize fan performance by optimizing the shape, number and pitch of blades with hub diameters. Steel wheel and heat-fan construction with bearings tunnel cooling system is capable for handling high airstream temperatures and ideal for industrial oven and dryer exhaust systems where pressure requirements are minimal and compact light-weight designs are advantageous. With heat fan construction Duct Fans are capable of handling airstream temperatures to 725 deg. F.

Canada Blower Duct Fans provide relatively large volumes of air (to 100,000 CFM) at static pressure up to 3" WG).
