Canada Blower Duct TubeAxial and VaneAxial Fans

Canada Blower and Forge Duct Tube Axial and Vane Axial Fans for variable volume air handling applications utilize adjustable pitch high efficiency aerofoil aluminum fan propellers to provide optimum performance. Buffalo Type VPS Adjustax Axial Fan have an internal blade pitch adjustment, which allows to bring variable air volume capability for air conditioning, heating and ventilating applications.

Clamshell Design Vaneaxial Fans are used primarily in applications where ready access to the interior of the fan is desired. The entire bearing assembly can be removed quickly and easily, without removing the fan from the stack. Heavy duty pillow block anti-friction bearings with split inner ventilator cylinder are standard. Clamshell design vaneaxial fans are avaiable with steel wheels and aluminum wheels.

Spray Booth Design Vaneaxial Fans are available in standard belt drive arrangement 9. These fans are designed for use in spraybooth installations, or in a variety of applications where requirements make it necessary to clean the fan periodically. Standard accessories include: inlet / outlet cones, inlet bell, screensfor fan, cone, or bell; belt guard, weather proof motor and drive cover, spark resitant construction with aluminum fan wheels, or steel wheels with bronze tipped blades; support legs, suspension clips, shaft seals are also available as standard fan options.

Spark Resistant X-proof construction on tubeaxial and vaneaxial fans is available in all aluminum airstream (AMCA A) construction; aluminum wheel (AMCA B) construction; and steel wheel with bronze tipped blades and shaft retainer (AMCA C) construction.

High temperature ventilator construction: upon request Buffalo vaneaxial fans can be furnished with optional high temperature construction for oven exhaust, or combusting gases exhaust applications.

Corrosion resistant construction and chemical duty construction: for corrosive environment all vaneaxial fans are available in FRP construction, as well as in 304 SS, 316 SS, or 316 L stainless steel construction. Special coatings are optional and selection is made based on the application.

Positive Pressure Blower is a high volume fan use to pressurize a burning structure, in case of fire, in order to force the smoke out. Positive Pressure Blowers are portable, gasoline powered fans, most of which utilize a 5.5 horsepower engine. The theory of positive pressure ventilation is based on the principal of even pressure distribution. Once a structure is pressurized, air and smoke can be forced out through any opening (similar to escaping from an inflated baloon).

Electric smoke ejectors (negative pressure ventilation) can be used for smoke removal but this has proven to be inferior to positive pressure ventilation.

What makes Positive Pressure Ventilation superior to negative pressure ?

* The risk of injury from the engaged structure is reduced while placing the fan in operation.
* Positive pressure ventilation is faster to set up and requires fewer personnel.
* The Positive Pressure Blower has a self contained power source, while electric fans require cords and adaptors.
* Smoke and heat is removed from all levels of the structure unlike negative pressure which can result in localized extraction.
* Quicker results. After initial knockdown, positive pressure ventilation can be initiated and will show immediate improvements in the interior conditions.
* It allows replacement of contaminants with vital cooler, cleaner air - especially in sealed or windowless buildings. It's also very effective in large and compartmentalized buildings, warehouses, schools, etc.
* Quick results allow firefighters faster entry due to lower heat levels and improved visibility.

The following criteria should be considered for effective use of Positive Ventilation:

- The cone of air must cover the intake opening. The fan must be placed the correct distance from the structure such as that the cone of air forms a seal around the opening.
- The size and location of the discharge is important. The discharge, if at all possible should be as high and far away from the intake as is practical. The discharge size should be between 3/4 to 1/2 times the intake. This may not always be possible as the fire may have already dictated discharge locations and sizes; but whenever there is a choice, the above criteria should be used.
- It is important to control the ait flow between the intake and discharge. Positive pressure ventilation can move air long distances if proper control is maintained by opening and closing doors, windows, etc. It is important that firefighters understand not to open the structure too much: ie breaking windows, etc.

The standard features of Canada Blower Positive Pressure Ventilators include: fold down "T" handle; 8" pneumatic tires with full width axle; a "tilt and lock" device that allows the unit to be angled 20 degrees up or down with infinite positions in between; sturdy and light 1 inch wrap around frame. Explosion proof electric motors are available as drivers too.
