Canada Blower BD roof ventilator is a versatile, high discharge fan. This ventilator features a taller design than typical centrifugal or propeller roof ventilator fans and is especially useful in the discharge of smoke and / or fumes high above the roof line and away from surrounding ventilation systems. Three part assembly consisting of stack cap, fan section and base. Features cast aluminum airfoil blade propeller. Standard Canada Blower fan construction is heavy-gauge steel finished with air-dried gray enamel. Hot dipped galvanized, stainless steel or all-aluminum ventilator construction are optional.
Low Profile Canada Blower Hooded Roof Ventilators provide cost effective, general purpose ventilation solutions for commercial and light industrial ventilating applications. The aesthetically pleasing modular hood design minimizes extension above the roof line. Both direct and belt driven fan models are available in exhaust and supply configurations. A wide array of adjustable pitch, cast aluminum ventilator propellers are available to meet specific fan performances and application requirements. Canada Blower also offers a complete line of ventilator options and accessories such as roof curbs, backdraft dampers, disconnect switches and special coatings to maintain single source responsibility.
A simple roof ventilator is essentially an opening in the roof with a cover to keep out rain and to prevent winds from interfering with its functioning. Natural convection is an appreciable aid to ventilation in a large building only if it contains sources of large amounts of heat. A further useful adjunct is a fan fan, device for agitating air or gases or moving them from one location to another. Mechanical fans with revolving blades are used for ventilation, in manufacturing, in winnowing grain, to remove dust, cuttings, or other waste, or to provide draft for a fire. The addition of distribution ducts to the fan and a system for forcing air into the building provides greater efficiency. Outlets are designed to attain maximum mixing of air and to move large amounts of air at low velocity so that temperature layers are eliminated. Factories have special suction hoods and enclosures to draw away localized dust, fumes, and heat. Incoming air may be cleaned of dust by filters or electrostatic precipitators.
Deep mines, underwater tunnels, and other subterranean and submarine environments require elaborate mechanically operated systems for maintaining the air supply in a healthful condition. The lives of those working in, or traveling through, such areas depend upon a constant supply of fresh air; not only must the systems used be highly efficient, but there should be provision for emergencies in case of failure of the apparatus in operation. An outgrowth of studies of problems of ventilation is the development of methods of air conditioning heat pump is a reversible device that does mechanical work to extract heat from a cooler place and deliver heat to a warmer place. The heat delivered to the warmer place is, approximately, the sum of the original heat and the work done.
Such ventilation systems, unlike ordinary methods of ventilation, are independent of outdoor atmospheric conditions and can, therefore, maintain the indoor atmosphere at the most healthful temperature and humidity and can free the air of dust and other undesirable materials. They accomplish this, however, at a considerable cost in energy.
Roof ventilators are another option. They work in both summer and winter. In summer, roof ventilators reduce the build up of heat in the ceiling spaces, reducing the heat load on your insulation, meaning that the insulation works more effectively. In turn, you will save on your electricity bills as the air-conditioning systems will not have to work as hard. In winter, it reduces the amount of condensation that forms when warm, moist air from exhaust fans meets cold surfaces. Roof ventilators will also reduce the amount of corrosion and timber that occurs because of condensation. Roof ventilators should be installed where there is sarking underneath tiled roofs, when metal deck roofing is used, and when there is evidence of condensation in the roof spaces or ceilings.

An economical in-line fan design - Canada Blower Mixed-Flow Fans.
Canada Blower Upblast Roof Ventilator is designed for heavy duty exhaust and well suited for continuous use. Each Canada Blower Upblast Roof Ventilator features a steel base plate welded to tubular steel struts to form a strong support for the motor and fan mounting base. All Upblast Roof Ventilators use statically and dynamically balanced airfoil fan propellers for optimal performance and longevity. The fan’s rolled steel circular windband cuts down on wind resistance and is easily removable for access to the motor and fan propeller. Fan flanges are integrally formed for increased strength. Upblast Roof Ventilator is constructed with close tolerances between the propeller tips and the exhaust orifice to take advantage of the propeller’s full area for maximum efficiency.
Canada Blower Upblast Roof Ventilator also features a set of free action, positive force dampers as standard. Fan dampers open automatically when the fan turns on and close when the fan is not running. During blower operation, discharge velocity prevents rain or snow from entering the fan. Air dampers for Canada Blower Upblast Roof Ventilator ride on rust free bearings to reduce maintenance and increase life. L2 blade and L4 blade propellers are used throughout the size range in both direct drive and belted fan models. Direct Drive Upblast Rood Fan uses steel construction as standard. Hot dip galvanized, stainless or all aluminum construction is optional. All fans are cleaned, chemically pretreated using a phosphatizing process and painted inside and out with a light gray enamel finish.
Belt driven Canada Blower Upblast Roof Fan uses the same steel construction, and is also available in hot dip galvanized, stainless and all aluminum fan construction. Canada Blower Belted Roof Ventilator offers a more economical approach to a low-speed, quiet upblast roof ventilator for handling noncontaminated air. Since fan belts and sheaves are in the airstream, the ventilator should not be used to handle high temperature or corrosive air. Drive selection for these fans carries a rating of from 1.3 to 2 times the normal satisfactory capacity.
Canada Blower Hooded Roof Ventilators are high capacity, general supply or exhaust fans well suited to applications that require the quiet and efficient movement of large volumes of air in both commercial and industrial environments. Hooded Roof Ventilator is constructed of heavy-gauge steel panels, a steel base plate welded to tubular steel struts and a deep smooth orifice to allow for greater airflow efficiency. All Hooded Roof Ventilators use statically and dynamically balanced airfoil fan propellers for optimal blower performance and longevity. Sizes 24 thru 60 use a fan hood that is constructed of heavy gauge galvanized steel. Corrosion resistant fiberglass reinforced plastic hoods and other special materials are also available. Fan hoods are attached to the fan with heavy structural angle supports for added stability. The Hooded Roof Ventilator is constructed with close tolerances between the propeller tips and the exhaust orifice to take advantage of the propeller’s full area for maximum efficiency.
Canada Blower Low Profile Upblast Propeller Roof Ventilators provide general exhaust of commercial and light industrial buildings while offering a pleasing low profile design that minimizes extension above the roof line. The upblast fan design discharges air and contaminants up and away from the building. These Canada Blower ventilators exhaust large volumes of air at low to medium static pressures. Typical applications for upblast propeller roof ventilators include warehouses, shopping centers and manufacturing facilities. A wide array of adjustable pitch, cast aluminum fan propellers are available to meet specific performances and ventilating application requirements. The cost effective design is available in both belt and direct drive configurations. Application flexibility, cost competitiveness and robust design all combine to make Low Profile Upblast Propeller Roof Ventilators an industry leader.
