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.

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. A damper fan is a duct-like device used to neutralize temperature through ventilation ducts. There are many damper manufacturers who produce fire dampers that help prevent the spreading fires in buildings and houses. These fans are designed to close once subjected to heat and/or fire. Engineers and architects are incorporating fire dampers in their design to effectively reduce the damage that a fire can cause. A dampers manufacturer makes sure that its products are safe for use by consumers. They make certain that their products materials are of the highest grade and quality so as not to risk the safety of the building where the fans will be used. Up-Blast Ventilators incorporate elements of sealed and high-temp. consturuction for emergency fume and smoke exhaust.
