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.

Canada Blower industrial backward curved fan is well-known durability and established performance. Available as a pre-engineered fan line, it delivers the reliability of a custom designed fan at the price and lead time of a standard production fan. Whatever your needs Canada Blower BI fan has the flexibility to fit your ventilation application. The fan wheel uses heavy backward curved ventiltor blades designed to handle dusty and harsh environments. The solid steel fan blades are also ideal for custom applied corrosion resistant coatings making Canada Blower BI blower even more versatile. Typical BI fan applications include dust collectors, thermal oxidizers, emission control systems, fume exhausters, and air filtration systems. The Design 95 can also be used in clean air applications, such as general ventilation, exhaust, forced or induced mechanical draft, air recirculation, and drying.

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.


Canadian Blower petrochemical fans and blowers operate in conditions encompassing extreme pressure and temperature, and handle a wide range of gases containing aggressive and toxic components. Petrochemicals industry provides the widest range of challenges for rotating equipment. Demanding specifications and strict safety requirements must be met and above all is the need for dependable operation over long periods.

Canadian Blower fans meet the challenge of moving gases continually, reliably, efficiently and safely. They are built to API, or equivalent industry standards and their performance has been proven over many years of operation; and the blowers can meet unusual requirements that include dual drive systems with automatic drive engagement/disengagement and special materials of construction.

Canadian Blower fans and pressure blowers are found in all major process plants. The range of applications is very wide but includes:

• custom engineered centrifugal process fans for combustion air supply. These may be used directly for fired heaters for ethane or naphtha cracking plant and for processes with steam reforming such as methanol, or for boilers serving general utilities. Flue gas extraction and tail gas clean up are among the other applications for which we have supplied custom fans.
• auxiliary boiler and other pre-engineered fans.
• cooling fans for mechanical draught cooling towers, air-cooled heat exchangers and air-cooled condensers.
• turbo blowers for sulphur recovery combustion and reaction air, sulphuric acid and carbon black plant
• screw type pressure blower systems for process gas handling, notably for butadiene plants,  gas turbine gas fuel compression and process refrigeration.
• reciprocating turbo blowers for hydrogen processes - hydrocracking, visbreaking, catalytic reforming
