Up-Blast Power Roof Ventilators

Canada Blower PRV Power Roof ventilators provide clear evidence of the continued leadership of Canada Blower in the engineering development and manufacture of ventilating fan packages for industrial and commercial ventilation. CBC Company axial roof fans cover sizea ranging from 15" to 84" wheel diameters with capacities from 2000 CFM to 200,000 CFM.

PRV Power Roof Ventilators is a low-silhouette, factory assembled package fan unit constructed to withstand hurricane force winds. It construction incorporates galvanized steel wind band, rain gutter, automatic dampers (gravity action) with damper bearings and damper stops, optional stack for true vertical discharge, gussets to fasten the wind band to the stack, streanlined die formed Venturi closely shrouding fan propeller / wheel, heavy duty prop supplied in variety of designs, roof curb sheet with flanged edges, totally enclosed air over high efficiency motors, special coatings for corrosion and moisture resistance. This type of power roof ventilator is available in Tilt-Up construction, which provides access to drives and motors direct from the roof.

CBC AF Type Power Roof Ventilators utilize vaneaxial and tubeaxial fans to which a separate damper head and curb sheet are attched. Their construction incorporates flanged wind band, or shroud with rain gutter, supplied with integrated gravity automatic dampers pivoted in bushing bearings, dampers stops and flange, tube axial, or vane axial fan stack, available in direct drive - arrangement 4, or belt drive with belt tension adjustment arrangement 9 configuartion, motor cover, or belt gurad, gussets, heavy duty fan wheel, available with a variety of motors, corrosion an dmoisture resistant finishes.

FRP Construction - Fiber Reinforced Polyester corrosion resistant construction is available for all up-blast power roof ventilators along with protective coatings for corrosive exhaust fumes or atmosphere including synthetic vinyl plastic and a cathalytic epoxy coatings.

Corrosion resistant construction and chemical duty construction: for corrosive environment wall fans are avaialble in 304 SS, 316 SS, or 316 L stainless steel construction.

Emergency Duty Purge Up-Blast Ventilators incorporate elements of sealed and high-temp. consturuction for emergency fume and smoke exhaust.

Super high temperature fans are offer as centrifugal amongst other types. People these days opt to use fans for their ventilation needs. A mechanical fan often has many uses around the house and inside buildings. This versatile appliance can serve as a cooling instrument especially during the summer and it can also be used during winter to push warm air down in order to heat a room. In the industry, there are many types of fans such as axial fans, centrifugal fans, crossflow fans and bladeless fans. These types of fans have features, structures and benefits. Each one offers different processes and ways of balancing the temperature. Their usage also depends on the kind and size of the room that needs ventilation. This enables engineers to choose the right kind of ventilation that will coincide with the design they have in mind for their buildings. Corrosion resistant construction and chemical duty construction: for corrosive environment wall fans are avaialble in 304 SS, 316 SS, or 316 L stainless steel construction.
