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 fan performance. Buffalo Type VPS Adjustax Axial Fan have an internal fan 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 fan 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 ventilator accessories include: inlet / outlet cones, inlet bell, screens for 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 fan 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 fan coatings are optional and selection is made based on the application.

In the axial flow ventilator the air must blow in line with the axis of rotation and there must be blades with space between them.  With few exceptions, the axial blower or fan must not have a lot of back pressure and will work a lot better if the blade is shrouded.  One obvious exception is the turbine compressor used in jet engines, but this requires very tight fittings and very high speed so the air is being rammed in against the outgoing air much faster than it can move - it uses a lot of power and makes a lot of noise.  Shrouding works better because the greatest loss in an unshrouded fan is the air coming off near the tips and immediately turning out and back circulating only through the fan and not through the room. The most common shrouded fan people see is muffin style fan in computers.  An axial blower can have multiple sets of blades and the blades can even over lap so light is not visible through the fan.  Fans are used most often for moving large quantities of air between spaces at atmospheric pressure.
 
Centrifugal blowers come in a number of forms of which the most common is the squirrel cage blower.  The common factor is the air is moving perpendicular to the axis of the part that is moving the air.  Typically, the air is drawn in through the side of the unit, turns at low speed to encounter the inside of a spinning cylinder with ribs or vanes around the wall of the cylinder which fling the air out and away where it is captured and aimed through an outlet much smaller than the inlet.  Think of taking an open tin can, drilling a hole in the center of the bottom to take a bolt as an axle and cutting slots up the sides, bending the material of the slots in, then spinning it with a drill.  A variation looks like a plate with ribs running from the center and increasing in height toward the rim, the air being thrown off the rim.   The name squirrel cage comes from the appearance like the tread wheel small rodents use for exercise - I suspect it is not called a hamster tread wheel because that is too precise - or childish. Blowers can have higher output pressures, but not a lot higher and they lose capacity rapidly with increasing pressure.

Aside from the small squirrel cage blowers used on some electrical equipment, the most common blowers of this type are the units used for drying carpet after cleaning or a fire, the blowers used for leaf sweeping and the unit hidden inside a vacuum cleaner.

Caution is necessary in selecting blowers for series installation. It is generally accepted that most pre-engineered blowers are capable of withstanding twice their catalog rated static pressure. In other words, where two blowers are installed in series the second blower housing should withstand the higher pressure. There is, however, a need for concern when the combined pressure exceeds twice the rated static pressure for one blower. In series applications involving three or more blowers, or in any system in which positive or negative pressure exists prior to the consideration of the blowers, special housing reinforcement may be necessary.
