VaneAxial Fans

Chicago Blower VaneAxial Fans for variable volume air handling applications utilize adjustable or controllable pitch high efficiency aerofoil aluminum axial fan wheels to provide optimum performance. CBC variable pitch vaneaxial fans have an internal blade pitch adjustment, which allows to bring variable air volume capability for air conditioning, heating and ventilating applications.

Chicago Blower Design 47 Vane Axial Adjustable Pitch Fans are used in applications where demands vary with system or seasonal change. Fan blade pitch is manually set to increase or decrease performance. Ventilator blades are easily adjustable externally at the hub. Available in compact direct drive fan models.

CBC Design 47 Vaneaxial Fans features include

• Vary volume and pressure by manually resetting ventilator blade angle
• Stable fan air flow over entire performance range
• Compact direct drive configuration
• Horizontal or vertical fan installation
• High Efficiency airfoil bladed fan wheel
• Efficiencies over 80%
• Rugged industrial strength construction
• AMCA Certified for air and sound performance

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 fan 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 wheels, or steel wheels with bronze tipped blades; support legs, suspension clips, shaft seals are also available as standard options.

Spark Resistant X-proof fan 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.

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 fan bearings with split inner cylinder are standard. Clamshell design vaneaxial fans are avaiable with steel wheels and aluminum wheels.

High temperature ventilator construction: upon request Chicago Blower  vaneaxial fans can be furnished with optional high temperature fan 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 coatings are optional and selection is made based on the application.

Axial fans are the typical household fans we see every day. This type of fan has three or more blades that rotate to allow air to pass through and circulate around a room. Axial fans are operated by electricity to balance the temperature and permit air to flow inside a room.

Canada Blower Co. has developed high pressure blowers-in-series systems to achieve static pressure, previously unachievable by single stage centrifugal blowers.

Series and parallel connected blower installations are often used to meet performance ranges beyond normal single stage blower capacities. For systems that require high static pressure, and especially high pressure TOGETHER with high temperature (where standard multi stage, positive displacement, screw, or regenerative type blowers can not be used) series of single stage centrifugal blowers can be used. Many times additional blower in the system can be advantageous. For instance, where two blowers are operating in series and one breaks down, the other may be able to "limp" the system along while the necessary maintenance is performed. Having on blower continue in operation can often allow limited production while the other is being repaired. Also, there are cases where having one blower continue in operation could prevent or at least minimize system or equipment damage from such things as high temperature of contaminated airstreams.
             
Another advantage of blowers in series is that of the available space. If system must be expanded and increases the CFM requirements, the allotted space for the original blower may not be large enough for a single large blower, but might be large enough to install two smaller blowers in series to obtain the necessary pressure.
 
One more potential advantage for series operation is the likelihood of initial cost savings. Although each case must be evaluated individually, it is often more economical to select two "smaller" blowers with their respective smaller motors and drives than to select one "larger" blower to do the job.
Series connected blowers are those which have the outlet of the one blower exhausting into the inlet of another blower. By connecting blowers in such a manner, high static pressures can be attained. This is accomplished as the second blower adds its pressure capability to the system, increasing the capacity beyond the capabilities of the first blower.
 
Ideally, two identical blowers installed in series would result in the same CFM at the outlet of the second blower as the inlet of the first one, and nearly twice the static pressure as that rated for either blower alone. However, some variation will result in both air flow and combined pressure because of the tendency of air to compress under pressure. A good understanding of how atmospheric pressure and absolute temperature affect density is required. Both of these factors are involved in the proper selection of blowers. Density is directly proportional to atmospheric pressure and is inversely proportional to absolute temperature (degrees Rankine).
 
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.
