Back-draft stack dampers are standard option. Disconnect safety switch is mandatory for roof mounted units.
Style H Sky-Vent Supply Power Roof Ventilators are supplied 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 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.
Style H Sky-Vent 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 arrangements: A, B, C, D, E, G, and G.
FRP Fan 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. Canada Blower
FRV fiberglass roof ventilator is designed for roof mounted exhaust
applications where corrosion resistance is a primary consideration. The
standard Canada Blower FRP resin used for the FRV is resistant to a
large variety of alkalis and other chemical agents. When a corrosion
resistant fan is required to withstand chemicals that attack glass or
polyester resin, special plastic and reinforcing fan material can be
supplied.
Corrosion resistant
ventilator 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.

Centrifugal / Radial fans offer regulated high pressure airflow that is required for several industrial applications and air pollution systems. Centrifugal fans are constant volume devices and can operate under high sensitive conditions such as high or low temperatures, corrosive gases, acidic fumes etc. There are several ways how a centrifugal fan can be used as a process fan in industries, such as in transporting air/gas, drying, cooling, material handling, air re-circulation etc.
Canada Blower Company is the engineering sales representative for Industrial and OEM fan and blower manufacturers in North America. Canada Blower fans are well know for their highest manufacturing quality, reliability and industrial toughness for many years across the world.
Canada Blower Single-Width Airfoil Centrifugal Fans are the most popular general ventilation fans because they fulfill most commercial general industrial air moving needs. With its energy efficient airfoil wheel, the Canada Blower SW-AF fans are ideal for clean air applications.
Canada Blower Co. offers a PT Power Tube Make-Up Air System as one of the most economical options for larger industrial plants ventilation air make up.
When exhaust fans are used to provide ventilation, both for industrial and process exhaust and personnel comfort, a negative air pressure is created within the building. This negative pressure causes several problems:
- Process exhaust ventilation systems are less efficient and may not work properly.
- Down flow can occur through gravity vents and result in the back venting of products of combustion from flues and stacks of heaters and process equipment.
- Drafts are created that are a discomfort to employees. Safe operating of outside doors may even be impaired.
Canada Blower Power Tube Fan Make-Up Air System solves all of these problems economically, even on the coldest winter day.
In the winter, conventional make-up air systems have to heat the cold outside air prior to introduction into the building. This is an expensive process in both equipment and continuing energy cost. The Power Tube Fan Make-Up Air System is a simpler system that utilizes wasted building heat and basic aerodynamic principles for supplying, tempering and distributing make-up air. And that makes it less expensive than conventional make-up air systems to purchase, to install and to operate.
Canada Blower PT Power Tube Fan Make-Up Air System uses a special propeller fan with straightening vanes and fan housing mounted to an opening in a building sidewall near the ceiling (an optional roof mounting model is available). A motor operated wall shutter is attached to the outside wall opening under a protective weather hood. A long specially constructed reinforced polyethylene tube is connected to the fan discharge orifice to carry fresh outside air throughout the building and temper it by mixing cold outside air with warm inside air near the plant ceiling before it reaches floor level.
Specially sized and spaced discharge holes in the polyethylene tube produce relatively high velocity turbulent jets of air. This turbulent jet flow swirls and mixes surrounding air particles resulting in the entering of the warm ceiling air and the complete tempering of very cold outside air within a relatively short distance. The result is heated make-up air at the price of unheated make-up air.
Canada Blower Power Tube Make-Up Air Fans are available in Sizes 18 to 48 for for air flows up to 40,000 CFM.
Canada Blower PT Power Tube Make-Up Air System tube is constructed of thick woven high density polyethylene fiber (8 x 8) laminated with poly coating to a thickness of 6 Mils. It is 3.8 oz. per square yard material. Burst strength is 118 Lbs per square inch. The material is flame retardant and complied with NFPA Standard 701. Tubes are available in two colors: blue and white. One end of the polyethylene tube is factory sealed.
Sufficient make-up air should be provided to balance exhaust from general ventilation and process ventilation. Usually several Power Tube Fans will be required, located to distribute air throughout the plant. If additional tempering of make-up air in specific plant areas becomes necessary, unit heaters can be added.
