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.

Engineering sales of air knife blowers, blow off fans, stainless steel fans and SST blowers, spark resistant ventilators, combustion blowers, vane axial / tube axial blowers, high pressure ventilators, sealed blowers and fans, FRP fiberglass ventilators.
High temperature fans and blowers for industrial applications:
  Fans have helped to create safer and more pleasant internal environments for hundreds of years. The invention of mechanical fans is found in the industrial revolution and the first commercially viable electric fans were made available to the US public early in the 1930's.

Today the technology behind fan manufacturing and ventilation solutions have sky-rocketed to create fans for virtually every use from cooling devices in a server room; to ventilation in a manufacturing plant; to keeping a bathroom clear of damp air.

Generally speaking, fans and their accessories can be divided into 3 main usage categories: domestic use, industrial use and commercial use.

Industrial Fans will often have a very robust requirement and it is essential to involve experienced engineers with the installation of such ventilation. Other than just determining whether the fans will be required for air supply or for exhaust functions (i.e.: as an extractor fan) the engineer or installation technician will need to be keenly aware of both the working temperatures of the units as well as any thermal protection qualities of its associated housing or frame.

Some industrial fans will come with controllable speeds which can be very handy in a changeable internal environment, especially with regards to saving on ventilation costs at times when the air regulation needs of an area are reduced. Special features such as built in monitoring and systems integration come in handy when working in a potentially hazardous environment for example when chemicals or volatile substances are involved. Generally speaking, fire resistance and corrosion resistance are both 'plus' features for any industrial ventilation setup. Above the 'plus' one will need to consider the health and safety requirements of your region such as vibration or noise control and air quality regulations related to worker health.

Commercial Fans would not have as robust a requirement but the overall integration of fans into the building structure and management system is key to efficiency. Automatic ventilation in refrigeration units or in rooms that will typically contain many people at the same time will keep areas safe and comfortable. Operational areas such as server rooms (also known as data rooms) and elevators will need to provide adequate ventilation, usually in the form of extractor fans, to remove excess heat generated by the operating machinery which often runs continuously. Commercial ventilation also acts as a barrier to unwanted external influences such as insects, pollution and natural allergens.

Lastly domestic fans find their main purpose in providing less costly air quality solutions. There are two ways to cut costs with a domestic ventilation solution. You can invest in a 'cheap and cheerful' unit from the beginning resulting in a smaller initial cost or you can install a slightly more costly fan and ducting system with operational features that help you save on heating and ventilation costs in the long run. There are a wide variety of low energy extractor fans and ventilation units are now available for kitchens, washrooms and living rooms. In addition heat recovery units now help you to use the heat from stale air that is being extracted to warm-up fresh air that is being pulled in by your system.
