Power Roof Ventilators and Make-Up Air Fans

PRV Power Roof Ventilators provide clear evidence of the continued leadership of Canada Blower in the area of ventilating fan packages for industrial and commercial ventilation. Canada Blower supplies axail hooded fans covering sizea ranging from 12" to 120" wheel diameters with capacities from 2000 CFM to 200,000 CFM, and heating capacity up to 4,500,000 BTU/hr.

Axial Exhaust Power Roof Ventilators are factory assembled package fan / blower units constructed to withstand hurricane winds. Its construction incorporates mushroom fan head, or hood head with bird screen, which is hinged to a box-style stack, supplied with access door. For higher capacities stack can be substituted with tubeaxial, or vaneaxial fan. Curb caps are welded to the curb side of the stack. Fan panel assembly is located near the top. Backdraft stack dampers are standard option. Disconnect safety switch is mandatory for roof mounted units.

Axial Supply Hooded Power Roof Ventilators are offered with optional filter rack and filter package protected by bird and insect screen. Motorized back draft dampers are standard on all supply air fans. Filtered mushroom fan head features channel type filter racks, bird screen, hinged connection to the stack box. Special coatings are available upon request.. Fan panel is of double orifice design to allow for supply/exhaust, or reverse-flow operation. Discharge diffusers are available in variety of styles.

Make-Up Air Roof Ventilators are available with direct gas fired heater, or steam/hot water coil packages. Seven arangements are available for efficient control of the air flow in various modes on operation: fresh air /return air /by-passs air, in various mounting arrangements.

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

Corrosion resistant construction and chemical duty construction: for corrosive environment all fans are avaialble in 304 SS, 316 SS, or 316 L stainless steel construction. Spark resistant construction is available in all aluminum construction; wheels are made of special alloys for non-sparking airtsream construction.

Mixed flow blowers combine characteristics of both axial and centrifugal fans, and in the Canada Blower design the impeller resembles a fixed pitch axial fan. Canada Blower has two ranges of mixed flow fan: one heavy duty, ideally suited for handling dust-laden gases, and a compact range that gives higher pressure rises than can be obtained from similar sized axial fans. 

Canada Blower compact mixed flow fan is a fully ducted, in-line machine that has a non-overloading power characteristic. It is capable of operating throughout its pressure / volume curve without stalling, even at zero flow. This fan is ideally suited to applications where space is limited and, for example, is commonly used for ventilation on offshore oil platforms. Its robust design maximises reliability and, with anti-spark features, it is suitable in zone 1 hazardous areas. Belt and motor drive options are available. The range can produce flows up to 80m3/s at pressures up to 3 kPa.

Canada Blower heavy-duty mix-flow fans are extremely robust, with plate blades that are ideal for handling dust-laden gases at elevated temperatures. Though a mixed flow fan is not as efficient as other types and the operating range is more limited, fan performance is less degraded by erosion or corrosion. Should repairs be needed the blades are easily welded. Heavy duty mixed flow fans are available with flows from 200 to 1000 m3/s and pressure rises up to 8 kPa.

For applications ranging from the latest high-speed locomotives to industrial cleaning vehicles, Canada Blower can design a fan to satisfy OEM cooling, ventilation and other air movement needs. Through concept engineering, prototype and production, we provide a complete service for OEM air movement needs. Canada Blower OEM experience spans a wide range of applications from custom-designed, heavy-duty fans for use in locomotives and off-highway vehicles to standardised, light duty commercial air handling fans.

OEM axial fans are available for for traction motor cooling, inverter cabinet cooling, dynamic braking grid cooling, inertial filter exhaust, alternator cooling, generator cooling, radiator cooling and cab ventilation. Canada Blower have low-maintenance, high-reliability designs for applications where shock and vibration are problematic. Corrosion-resistant coatings and low noise compact designs are avilable too.

Canada Blower have quality assurance and performance testing to ensure your OEM fan will perform in the toughest working environments. Finite element analysis (FEA), vibration and shock testing, accelerated life cycle testing and sound testing can be provided too. Whatever are tough OEM requirements, Canada Blower has the experience and expertise to meet those needs.
