FANS APPLICATTIONS
AERATION
Aeration involves moving air through either a solid or fluid medium bed and is used for various purposes. Depending on specific material being aerated, our fans are utilized for moisture control in applications such as grain bin storage, and also provide oxygen and control moisture / temperature in composting applications. Due to varying environmental conditions, fans used in aeration systems often require special construction such as fiberglass, alloys and specialty coatings.
AIR STRIPPERS
Air strippers are used on drum filters for removing material build up on the filter. The vacuum nozzles on the filter remove the fiber/particulate, which are then disposed of or used for reclaiming the material. The fans used in this particular application require higher pressure at a relatively low airflow along with a radial blade design for handling the material. Because of these factors, Canada Blower’s Model RBW incorporates radial blades with a back plate to prevent long stingy material from collecting around the shaft.
AIR WASHERS
In the textile industry, humidity of the air is crucial for air quality and fabric production. The fibrous material manufactured in plants needs to maintain a specific humidity and temperature to be processed effectively. Textile manufacturers use air washers to cool, humidify, dehumidify and clean the air to prevent damage during production. Air washers balance the required humidity of the plant air by humidifying the air during the dry seasons and dehumidifying the air when conditions are more humid. This is accomplished by using re-circulated heated or chilled water that is sprayed into the air. Canada Blower fans are used to draw air through these air washer systems and typically provide adjustable pitch axial fans in the range of 2.5″ to 4″ static pressure. Regardless of the size of your operation and system requirements, Canada Blower Fan & Blower is capable of manufacturing virtually any size fan or blower to meet your exact specifications.
ATEX (ATMOSPHÈRES EXPLOSIBLES)
Since July 1, 2003, equipment manufactured for operation in potentially explosive environments has been required to comply with the European Directive 94/9/EC. This directive, commonly referred to as the ATEX Directive, applies to all countries in the European Union (EU) and the European Economic Area (EEA).
The ATEX Directive is a collection of EU directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods.
The European Committee for Standardization (CEN) published EN 14986 as a standard specifically for the manufacture of fans for use in hazardous areas. This standard is a guide specifically for fan manufacturers to comply with the ATEX Directive.
BAKING OVENS
Ovens in the automotive industry are used for baking and curing coatings after application. It is critical to keep the oven temperature even throughout the process and exhaust the emitted fumes and VOCs. Canada Blower provides a wide variety of wall mounted or floor mounted plug fans for meeting the performance requirements for any oven application. Our radial blade and backward inclined fans are commonly used for the high temperature requirements of exhausting the oven air.
BIOMASS
Biomass and Incineration are two new methods of generating power that utilize renewable biological fuels and refuse as their main fuel source. The process of converting these fuels into an energy source requires the use of specialized boiler system. Issues such as dust loading and corrosion can become major concerns if your system does not utilize the proper fan for exhausting particulate and gas emissions. That is why selecting the right fan is crucial for optimizing the performance and longevity of your overall system. We offer a wide range of underfire combustion air fans, overfire air fans and induced draft fans needed to stand up to the harsh operating environments.
BOILER SYSTEMS
Boilers are used in a variety of industries for producing heat and energy. Many boiler applications will burn fuel readily available on site, such as byproduct from the given process. An example of this is Bagasse, which is a fibrous matter that remains after sugarcane is processed to extract their juices. The bagasse is a biofuel used for many boiler applications. Fans in boiler applications are forced draft (FD), induced draft (ID), over fire air (OFA) and combustion air.
DUST COLLECTORS
Fans are an essential part of every dust collection system and are used to assist in controlling and conveying dust for numerous applications. Whether you are capturing welding smoke or sawdust – Canada Blower manufactures a variety of fan types for dust collectors. We offer backward inclined fans for use on the clean side of a filter, radial bladed fans for cyclone applications and an extensive line of top mounted and side mounted units.
ELEVATOR SHAFT EXHAUST
Elevator shafts require proper air moving equipment to provide smoke control in the event of a fire. Pressurization is used to prevent smoke from migrating through elevator shafts to other floors, similar to how fans are used to control smoke in stairwells. Today’s elevator pressurization systems are designed to allow elevators to be used by firefighting teams. However, some systems are designed for the evacuation of handicapped individuals. While small amounts of smoke in an elevator may be tolerated by firefighters, smoke in an elevator and its entry and exit paths is unacceptable. Canada Blower’s complete offering of smoke and heat exhaust fans are relied upon for elevator shaft exhaust / pressurization in emergency situations. Commonly used Canada Blower fans for these applications are: Smoke & Heat Exhaust Fans, Utility Sets, Gravity Relief Ventilators.
EXPLOSION-PROOF PROCESSES
Industry areas such as chemical, pharmaceutical and various industrial processes have explosive environments that require the equipment to be specially constructed to minimize the risk of gas or dust ignition. Fans are one of the items of industrial equipment that have potential to ignite either gas or dust from either sparks caused by contact of the fan impeller and housing, or because of fan motors with high temperatures, inadequate gas / dust ingress protection, or inadequate construction for prevent spark or flame propagation in to the surrounding atmosphere.
The likelihood of sparks with the fan housing is minimized through use of special types of spark resistant construction, depending on the type of protection required.
AMCA “A” Spark Resistant Construction: Highest degree of spark resistance. Airstream parts are constructed out of non-ferrous materials. Typically, aluminum is the non-ferrous material used, but for certain applications, such as high temp, where aluminum cannot be used, Canada Blower has the capability to use alternative materials including Monel, Inconel and Hastelloy.
COMMONLY USED FANS:
Centrifugal Fans
Pressure Blowers
Radial Bladed Fans
Radial Tip & High Efficiency Fans
AMCA “B” Spark Resistant Construction: Less protection that AMCA “A” construction, AMCA “B” construction consists of a non-ferrous impeller and non-ferrous rubbing plate around the hole through which the shaft passes. As with AMCA “A” construction, aluminum in usually the non-ferrous material of choice but can be substituted with the alternative materials listed for AMCA “A” construction.
AMCA “C” Spark Resistant Construction: Lowest degree of spark resistance. Utilizes only a non-ferrous rubbing plate that is typically constructed of aluminum but can be constructed out of the aforementioned alternative materials when appropriate.
In addition to spark resistant construction, motor construction appropriate to the explosive environment must also be considered.
UL explosion standards classify explosive environments according to Class, Group and Division. The class indicates whether 1. Gases, vapors, liquids are present, 2. Dusts are present, 3. Fibers and flyings. The Group specifies what types of vapors, dusts, fibers, etc. are present. The Division specifies the frequency of the presence of the hazardous substances.
Class, Group and Division are specified by the client, and Canada Blower works closely with our motor manufactures to determine the best motor that conforms to those specifications. Many of our fans are appropriate for explosion proof environments, but due to the interdependence of many factors, each situation must be considered uniquely.
FLUE GAS RECIRCULATION
Flue gas recirculation (FGR) is a highly effective technique used for lowering Nitrogen Oxide (NOx) emissions from burners. This is particularly crucial, as NOx is a significant pervasive pollutant that produces a negative array of health and environmental by-products. NOx emission levels can be greatly reduced in industrial boilers by reticulating used flue gases back into the system. This process lowers the peak combustion temperature and drops the percentage of oxygen in the combustion air/flue gas mixture, delaying the formation of NOx caused by high flame temperatures. Canada Blower offers a wide range of centrifugal blowers specifically designed to be used with FGR systems.
GENERATOR ROOM VENTILATION
Generator rooms require a wide range of fans to optimize the performance of generators and other equipment. Exhaust fans are used to prevent heat buildup within the generator room, while supply fans are used to provide fresh air for combustion and efficient generator performance. Room size, space limitations and mounting capabilities will determine the exact type of fan needed for each specific application. As a leading manufacturer of air moving equipment, Canada Blower offers numerous fan types for meeting any generator room specification.

INDUSTRIAL OVENS
Ovens are used in a variety of industries for heating and drying product. As material is conveyed through the oven, plug fans are typically used for recircuclation air. This ensures oven temperature is uniform through each zone. As a product is dried or cured it also can emit VOCs, which must be exhausted. Oven exhaust fans carry these gases to atmosphere or to a scrubber or oxidizer depending on the concentration levels. We offer a variety of pedestal and pedestal plug fans with high temp features, such as shaft coolers, leak-tight construction and insulation, which are common on high-temp oven exhaust fans.
INDUCED DRAFT
Induced Draft (ID) fans are used to create a vacuum or negative air pressure in a system or stack. Our centrifugal blowers are used to maintain elevated ventilation, resulting in increased system efficiency. Canada Blower can also supply extractor fans, which are typically heavy-duty construction to handle particulate in the airstream. In the boiler industry, ID Fans are often used in conjunction with FD fans to maintain system pressure that is slightly lower than ambient.
KILN DRYERS
Kiln dryers are used to dry a variety of powdered materials for purposes as diverse as food production to building materials. The fans used in these dryers remove the high moisture content by forcing heated air across the material. Kiln drying applications for the cement industry use our fans to move large volumes of gas through the kiln system and thoroughly dry the cement to lumpy nodules called clinker. Many of these fans require special materials and features to withstand a wide range of operating conditions associated with these environments. Canada Blower offers the most comprehensive line of fans and can manufacture any fan to your exact specifications and performance requirements.

LABORATORY & FUME EXHAUST
Laboratories and research facilities exhaust a wide variety of harmful fumes. In concentrated forms, these fumes can be hazardous to human life. Contaminated air must be exhausted in a way that prevents it from returning into the building and surrounding locations where people may be present. To effectively exhaust these fumes, which in many cases are corrosive and/or explosive in nature, fans are connected to one or more fume hoods to draw the contaminated air through. For proper ventilation, exhaust fans must be capable of moving air at high velocities to achieve a high plume height, as well as entraining clean ambient air to dilute the chemical concentration in the airstream. Canada Blower Fan & Blower offers a complete line of laboratory and fume exhaust fans for meeting the most stringent industry standards. Canada Blower laboratory exhaust fans are often constructed of specialty materials to withstand the fumes associated with these environments.
MINE VENTILATION
Ventilation is a crucial component for any mining operation. Inadequate ventilation can expose miners to high levels of dangerous gases, dust particulates and excessive heat. The consequences of prolonged exposure to these elements can pose a series of health related complications. We understand the significance of selecting the right ventilation equipment for maximizing the air quality in mines, which is why Canada Blower offers a comprehensive line of products suited for the most rigorous mining ventilation applications. We also offer many special design features such as non sparking units, explosion proof motors and specialty guards.
PARKING GARAGE EXHAUST
Enclosed or underground parking garages require ventilation to remove harmful vehicle emissions and other pollutants, while providing fresh air. Ventilation is also a requirement in the event of a fire to remove smoke and to provide a clear access for firefighters. Exhaust and supply fans are used in conjunction with ductwork to distribute air throughout the parking garage, providing a common system for both pollution and smoke control. Canada Blower manufactures a complete line of axial flow fans designed for parking garage ventilation systems.

SIDEWALL EXHAUST & SUPPLY
Sidewall exhaust and supply applications require panel fans to move large volumes of air at low static pressures. Panel fans are commonly used on the walls of warehouses and manufacturing facilities to supply outside air or to remove hot or noxious gases in exhaust configurations. Other typical applications include removing carbon dioxide from produce storage facilities, greenhouse ventilation and parking garages. Panel fans can be mounted directly to the wall panel, which is especially useful when ductwork is unnecessary. Each fan can be customized to the individual needs of the customer, including aluminum or stainless steel construction, explosion proof motors, gravity or motorized dampers, corrosion resistant coatings and fully reversible impellers. Commonly used Canada Blower fans for this applications are
Wall Mounted Fans.
SPRAY BOOTH EXHAUST
When removing fumes and overspray from paint booths, precise airflow is critical to an operation. The velocity must be low enough to keep consistent flow in and out of the spray booth, but at the same time the velocity must be high enough to carry the fumes and paint overspray out of the work area. Another common feature on booth exhaust fans is the ability to efficiently clean and service the fan impeller. On centrifugal fans, Canada Blower offers an industry leading swingout design and axial fans are available in both clamshell and swingout construction for ease of cleaning. Because efficiency and noise are a requirement for paint booth exhaust fans, we have designed a diverse range of products that can accommodate these requirements and cover a wide range performance.
