Industrial Fan Blowers

By: Oleg Tetchel


Axial flow fans or industrial axial fans move an air stream along the axis of the fan. The way these fans work is similar to the propeller on an airplane: the fan blades generate an aerodynamic lift that pressurizes the air. Axial TCF fans use a propeller to draw the air into the fan then discharge it in the same axial direction. Typical types of industrial axial fans include:

* Tube axial fans (also called duct fans),
* Panel fans (also called wall fans),
* Personnel coolers,
* Roof Ventilators,
* Air circulators,
* Vaneaxial fans

As specialists in air moving applications and equipment, Buffalo Fan Co. understands industrial blower technology and designs systems for a host of facilities and industries, and work with the best names in industrial blower equipment, including TCF, NYB, IAP. A blower can achieve much higher pressure than a fan, and can be used to produce negative pressures for industrial vacuum systems. In selecting the right industrial blower equipment to serve your needs, you must consider conditions such as:

- Required airflow through the blower;
- Static pressure through the complete system;
- Suction pressure at the blower inlet;
- Airflow conditions through the blower;
- Altitude at which the blower will be operating;
- Composition of what is going through the blower - for example, is it explosive or flammable ?

Buffalo Fan and exhaust TCF fans do not differ significantly from non-industrial types in their basic operation. The main characteristics that make blowers and fans industrial are the heavy duty construction, wheel type, shaft and bearings, materials and gauges used. Industrial Pressure Blower Co. will work through all of the necessary considerations in developing an industrial air movement system that best addresses your needs and provides you with the most advanced industrial blowers and industrial TCF exhaust fans from the leading manufacturers.

Propeller / axial wheel types may include:

- Fixed pitch
- Adjustable pitch
- Swept back design
- Impeller wheel
- Low noise
- Reversible

Bifurcated Fans are direct driven axial fans where the motor is encased in a metal box to isolate it from the airflow. The term "bifurcated" means split in two branches, or parts. In terms of a bifurcated fan, the fan is constructed so that the fan rests between two forked channels, which carry the air, creating a void behind the axis of the fan itself. This makes TCF bifurcated fans ideal for exhausting or re-circulating fumes, gases and hot air up to high temperatures. The bifurcated fan motor must have access to ambient air, and have non-overloading characteristics. TCF bifurcated fans are typically used when the motor needs to be shielded from hot gases or other threatening conditions.

HVLS fans blanket a very large area with constantly moving air to create an expansive comfort zone. As a result, the big ceiling fan (up to 24 feet in diameter) can create an evaporative cooling effect during the summer months while de-stratifying uneven floor to ceiling temperatures in the winter. This results in significant energy savings since the heating system cycles less frequently.
