Chicago Blower Canada Industrial Fans and Blowers

Industrial backward curved (BC) fan blower

To cover the widest range of system requirements, Chicago Blower offers a family of airfoil and backwardly curved fan designs with overlapping fan performance envelopes. To maintain high efficiency and maximum economy, the fan  system's pressure and flow requirements are matched to one of eleven wheel blade designs with varying rotor widths and diameters. The selected fan is then sized to exact duty requirements. Fan wheels are available with either Chicago Blower's proven hollow airfoil blades for clean air, or solid backward curved or backward inclined blades for dusty, dirt applications. With eleven blower rotor designs, custom fan sizing and duty matching blades, Chicago Blower builds the fan to meet exact system performance specifications.  Severe duty industrial backward curved blowers are supplied in welded heavy gauge steel construction to prevent flexing at high pressure. Available in direct drive fan arrangements 4/4V/4H/7/8 and belt drive arrangements 1/3/9. BC fans are available in single width single inlet (SWSI), or double width double inlet (DWDI). Capacities: to 500,000 CFM. Static pressure up to 70 inches water gauge depending on the class of construction. Typical class of construction is Class 1, 2, 3, 4 and 5.

The two most important criteria when specifying a custom heavy-duty fan are efficiency and reliability. Air handling systems are increasing in complexity with the addition of more restrictive emission controls and air cleaning devices. While the results have been a cleaner environment, system pressure requirements have risen significantly. As these requirements increase, greater levels of energy are needed to force the air or gas through the system. Operating efficiency of the fan has become much more critical. Every dollar saved on the purchase of a less efficient fan will be consumed in additional operating costs. Maximum fan efficiency will not only have a positive impact on the bottom line, it will have a positive impact on the environment. Greater fan efficiency results in lower power requirements and fewer natural resources consumed. Efficiency also influences sound levels. The more efficient fan will run quieter than the less efficient fan. The quieter fan will need less sound insulating materials, or none at all.

Mild steel wheels are of all welded construction. If higher pressure is required wheel can be furnished of high strenght steel. Stainless steel wheel in 304 SS, 316 SS, 316 SS, 2205 SST are supplied for corrosive applications, or high temeparature applications.
HANDLING CORROSIVES: Protective coatings, special alloys, and FRP construction are available to combat corrosion problems. Special coatings [up to 12 mil thickness] – special paints and spray coatings are available under a variety of trade names. Canada Blower works with experienced coating applicators who can apply coatings to meet a wide range of requirements. Alternate-material construction–Single-Width Fans can be constructed of aluminum or various stainless steels.
Arrangement 1, 8, and 9 fans can be constructed for elevated temperature operation with the addition of shaft cooler and guard and high-temperature paint for 650°F maximum airstream temperature. Arrangement 9 fans are also furnished with motor heat shield. If optional shaft seal is selected, a recessed cone is furnished. Note that the maximum safe wheel speeds decrease as airstream temperatures increase.
