General ventilation power roof ventilators designed for efficiency and economy.
Low profile PRVs are suggested for use in commercial and industrial applications including factories, warehouses, commercial buildings, machine rooms or any situation requiring the movement of air.
High profile PRVs are suggested for use in industrial
applications where it is necessary for the fan assembly to be located
above the roof
and where motor, belts and bearings must be isolated from the
airstream.
These upblast power roof ventilators are designed for long life, low maintenance and all-weather performance.
The proven upblast design is the most cost effective roof exhauster built today and offers the best value of all PRV types.
With many commercial and industrial buildings such as factories, warehouses, parking garages, shopping malls and department stores a means of venting hot gases and smoke in the event of a fire is required.
Our Type H PRVs are especially designed, built and proven by independent test to meet this essential need. They reliably extract large volumes of hot gases and smoke regardless of building configuration, location or weather conditions. They withstand high temperatures for long periods.
A reliable ventilation system that can operate during a fire is both vital and essential. It prevents smoke logging, allows people to escape quickly, minimizes damages to property and contents and enables firemen to attack the fire without hindrance.
These PRVs have the added advantage of providing normal day-to-day ventilation and in many cases can also be fitted with ductwork for use in multi-story buildings.
The unique Type H power roof ventilator concept provides a solution for emergency heat and smoke venting that is dependable under the most extreme circumstances.

Most hooded PRVs can be supplied less fan component for use as a gravity ventilator or as an air intake.
Combinations of these various types can be used and still maintain a uniform and attractive rooftop appearance.
Use of the power combination of hooded power roof ventilators assures an effective ventilation system at exceptionally low cost.
Type RE recirculators are multi-purpose power roof ventilators.
They are suggested for use in commercial and industrial applications where there is sufficient ceiling height to create a temperature differential between the floor and ceiling.
These applications include factories, warehouses and large commercial buildings.
Type RE recirculators function as normal power roof ventilators in warmer weather and as an energy saving recirculation system in cold weather.
Each unit is equipped with a reversible fan that redistributes warm ceiling air throughout the plant and reduces the building's heating requirement. WIth the flip of a switch, it can function as a conventional roof ventilator.Never before has the need for adequate workspace ventilation been clearer to safety experts. Factories, warehouses, mines, offices and all other places where workers spend their time must be adequately ventilated and heated or cooled in order to minimize risks to air quality and maximize comfortable conditions, which contribute to productivity.
Canada Blower axial fans and centrifugal blowers, in high velocity and other configurations, are used to move air through ventilation systems and remove air through exhaust ports. The agricultural, photography, automotive, food processing, packaging, paper making, printing, welding and textile industries all use industrial blowers for workspace ventilation and a host of other applications, some of which are moisture reduction in bathrooms, spas and gyms and cutting down on smoke and odors in cooking and food processing.
Canada Blower centrifugal floor dryer blowers are widely used to dry carpet after cleaning. They are also used in building maintenance applications to dry spills or clean up after water damage.
Canada Blower industrial blower can be designed in one of two configurations. Axial blowers, which are more easily recognizable to most people, feature curved ventilator blades that spin around a blower axis. The spinning motion of axial fan blades closely resembles the motion of the spinning hands on a clock. The curvature of the blower blades creates an imbalance of air pressure on either side of the fan. The difference in air pressure causes airflow. When the blades spin continuously, the blower airflow is continuous.
The same principle of pressure imbalance applies to the other fan configuration as well. Radial (or centrifugal) fans also feature spinning ventilator blades, but radial fan blades spin within the confines of an enclosure (which is called an annular housing), and their spinning motion more resembles that of waterwheel paddles than of clock hands. As the blades (which are called impellers) within a centrifugal fan spin, they draw air from the side of the fan into the enclosure.
The blower impellers create a quick airflow. That quickness is augmented by the effect of centrifugal motion because of the shape of the annular housing. The result is that a centrifugal fan can produce a higher-pressure flow of air than can an axial fan operating at the same RPM. This feature makes centrifugal fans more attractive than axial fans in many industrial applications.

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 problems. Process exhaust 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. Our Power Tube Fan Make-Up Air System solves all of these problems economically, even on the coldest winter day.
