Centrifugal Blower Manufacturer – Canada Fans Industrial Blowers & Fans

Industrial Fans Canada

People these days opt to use fans for their ventilation needs. A mechanical fan often has many uses around the house and inside buildings. This versatile appliance can serve as a cooling instrument especially during the summer and it can also be used during winter to push warm air down in order to heat a room.

Axial fans, centrifugal fans

In the industry, there are many types of fans such as axial fans, centrifugal fans, crossflow fans and bladeless fans. These types of fans have features, structures and benefits. Each one offers different processes and ways of balancing the temperature. Their usage also depends on the kind and size of the room that needs ventilation. This enables engineers to choose the right kind of ventilation that will coincide with the design they have in mind for their buildings.

Axial Fans

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.

Damper Fan

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.

Centrifugal Fan

A centrifugal fan manufacturer sells fans that are quite different from the other types of fans. This type of fan is composed of different instruments which control the fans speed. It is a typically larger mechanism compared to other fans to accommodate bigger structures like office buildings and factories. All of these fans aim to maintain the convenience of the people regarding temperature balance.

Some Of The Industries That Heavily Require Ventilation Are:

•Pharmaceutical Industry
•Biological Industry
•Chemical Industry
•Mining Sector
•Physical Research Industry
•Processing units

Industrial Fan Performance

Visual inspections of the ventilation system often reveal some easily rectified problems that can significantly impair performance. If the system has not been properly maintained, clogged filters or obstructed coils will reduce airflow. The greater the obstruction, the greater the loss in airflow. Any leaks in the ductwork will contribute to reduced performance, especially leaks around plenum bulkheads that can lead to recirculation of air. Worn flexible connectors are a common source of leaks and should be inspected regularly. If the damper linkage is out of adjustment, the damper may not be opening completely, thereby reducing performance. If inlet dampers are used, make sure they are installed so that the air is pre-spun in the same direction as wheel rotation. For all dampers, make sure there is sufficient clearance for the blades to open and close completely without hitting the ductwork or other system components. Last, for systems with either pneumatic or electric controls, make sure damper actuators are operating properly. Sharp changes in the direction of airflow at either the fan inlet or outlet will disrupt the flow through the fan and impair performance. If it is impossible to straighten the ductwork entering and leaving the fan, the use of inlet boxes and turning vanes can minimize performance losses.

Industrial processes and plant ventilation

Industrial processes and plant ventilation systems often need more air than originally designed. Increased production requirements, process changes, and facility renovations are a few of the major reasons. Additionally, the lack of adequate maintenance over time can negatively impact system airflows. This article discusses several procedures that can increase airflow. Often airflow can be increased by adhering to proper fan maintenance procedures as outlined in fan installation and maintenance literature.

Centrifugal Fans & Fan Speed

Fan speed can decrease by as much as 10% to 20% when belts are too loose, with a corresponding loss of airflow. A fan cannot perform as designed if the air flow surfaces are distorted by contaminants. Even in large fans, a sixteenth of an inch of build up can reduce performance. Centrifugal fans will move some air even when running backwards. While some types would use so much horsepower they would trip circuit breakers, other design s could run for years without being detected. Fan components may be out of position due to routine cleaning or painting or the wheel could have shifted during shipment. For backward inclined fans, the relation of wheel to inlet cone is very critical. Even a quarter of an inch can have a major impact. The fan’s installation and maintenance literature shows the proper positioning of the wheel to the inlet cone.

Low Airflow Problems

One of the easiest solutions to low airflow problems is speeding up the fan. While airflow is increased by speeding up the fan, so too are static pressure, noise, and power requirements. Therefore, while increasing the fan’s speed is an easy procedure with low first cost, the additional operating expense over time makes it the most costly solution. When increasing fan speed, it is necessary to check the maximum safe speed of the fan and make sure the motor is capable of the horsepower required to run the fan at the new speed. But never run a fan beyond its maximum safe speed.

Industrial Fans & Improving Airflow

On a first-cost basis, adding or replacing fan equipment is the most costly alternative. However, on a life-cycle-cost basis, considering operating and maintenance expense, it can be the least expensive, as compared to increasing the speed of an existing fan. Sometimes a second fan may be added, either in series or parallel with the original, although it may be more cost effective to simply upgrade the system with a new fan capable of the required airflow and pressure. Adding another fan in series will increase the airflow because of the additional pressure. The operating point of the new system moves further out/up the system curve. Where duct size is adequate to handle the desired amount of air but the existing fan doesn’t provide sufficient pressure, a second fan in series may be the best solution. However, make sure the ductwork can handle the increase in pressure. Adding another fan in parallel with the first will increase airflow due to the combined capacities. Because capacities are being combined instead of pressures, a greater increase in airflow will result for a given system. However, system pressures will also increase and caution is required to avoid the unstable operating area of the combined fan system.

When more air is required it is important to investigate the system on a step-by-step basis, considering the least expensive possibilities first. For existing systems that seem to have lost performance, fan and system maintenance is the place to start. Often, simply improving the efficiency of existing components will suffice. For systems that require greater airflow and / or pressure, increased fan speed is generally the first alternative. However, when large increases in performance are required, there may be no alternative but to purchase a larger fan.

Industrial Exhaust Fans

Exhaust fans can be grouped into two general categories: emergency smoke evacuation and process ventilation. Generally speaking, emergency smoke evacuation fans may never be used, but they must be installed and be capable of exhausting high temperature air and smoke in the event of a fire. In contrast, high temperature process ventilation requires continuous duty exhaust of high temperature air, fumes or particulate. Both application types are uniquely different requiring special construction and system design considerations. In this article, we will examine both types of exhaust applications, looking first at the emergency smoke exhaust category. Since emergency smoke exhaust deals with lifesafety issues, there are governing bodies in place that identify and regulate specific design and performance standards. The administration and organization of the various governing bodies is subject to modification based on the needs of the industry. Currently, four such agencies are Industrial Risk Insurers (IRI), Southern Building Code Congress International, Inc (SBCCI), the National Fire Protection Association (NFPA), and Underwriters Laboratories, Inc. (UL). IRI insures properties all over the world based on an informational manual, which details the construction requirements that belt drive emergency heat and smoke exhausters must meet in order to be covered by IRI.

SBCCI is a not-for-profit organization of government officials from the United States and several foreign governments, which serves a strong leadership role in the delivery of model building codes. The purpose of the NFPA can be summarized into three main categories. First, NFPA promotes the science and improves the methods of fire protection and prevention, electrical safety, and other related safety goals. Secondly, it obtains and circulates information on these subjects. And thirdly, it secures the cooperation of its members and the public in establishing proper safeguards against loss of life and property. The fourth organization is Underwriters Laboratories, Inc.. UL is a non-profit, independent organization that maintains and operates laboratories for examination and testing of devices, systems and materials to determine their relation to life, casualty hazards and crime prevention. UL has three safety standards that apply to emergency smoke exhaust products. UL705 is concerned with the mechanical and electrical construction to insure safe operation. All electrical components (motor, wiring, switches, enclosures, etc.) must be ULlisted. UL793 is concerned with the lifting mechanism for the butterfly dampers and the fusible link. In order for a product to be listed in the UL Directory under ÒPower Ventilators for Smoke Control Systems,Ó it must meet the requirements of both UL705 and UL793. Additionally, UL must witness a full-scale test of a fan operating for the required time at the specified elevated and temperature.

High Temperature Exhaust Fans

So what makes one fan more capable of sustaining higher temperatures than another fan? Each model has a recommended maximum operating temperature based on the construction materials, drive components, and airflow characteristics. The limiting temperature is determined to be the highest temperature that any component of the fan assembly will reach during any operating cycle. Similarly, the maximum operating temperature is typically determined to be the lowest temperature that begins to exceed the capacity of any one component. For example, in some cases the bearings may be the limiting component, while in other cases the fanÕs impeller construction material may be the limiting component. The construction material is perhaps the most obvious element of the fan to consider when dealing with a high-temperature application. In general, aluminum withstands maximum temperatures up to 250 F, standard carbon steel up to 750 F, and 316 stainless steel up to 1000 F. Critical components are many times constructed of ferrous materials to withstand the higher temperatures. If temperatures were to exceed 300 F, for example, aluminum would be eliminated as a construction material option. Other construction considerations include bearing type, drive component selections, means of ventilation and cooling of the drive components, and insulation options.

The most common way of simplifying construction and component specifications to accommodate high temperature applications is to maintain separate categories based on the specified temperature range and time requirements.

Canada Fans has four Heat Option Packages for high temperature operation. Heat Option I construction is designed for continuous operation between 200 F and 500 F. Heat Option II construction meets specifications requiring the fan to exhaust 500 F air for a minimum of four hours in an emergency smoke removal situation per IRI requirements. Heat Option III construction meets the specifications requiring the fan to exhaust 1000 F air for a minimum of 15 minutes in an emergency smoke removal situation per SBCCI. This construction also surpasses the IRI requirements for 500 F for a minimum of four hours. Heat Option IV construction meets specifications for UL Listed ÒPower Ventilators for Smoke Control Systems. This includes the IRI requirement of 500 F for a minimum of four hours, the SBCCI requirements of 1000 F for a minimum of 15 minutes, and the Snow Load Test for butterfly dampers in UL-793.

While it may be tempting to choose a higher heat option than necessary “just to be safe”, doing so can add considerable and unnecessary cost to the job. For example, selecting HT Option III when HT Option II is adequate adds insulation and high temperature bearings. These items would be considered “overkill” and add unnecessary extra costs.

Axial Fans & Blowers – High Temperature

Canada Fans Co. now offers high temperature construction on its axial fans. There are a few steps of fan heat construction available: 200 F, 725 F, 800 F. High temperature inline fans are ideal for industrial oven and dryer exhaust systems where pressure requirements are minimal and compact light-weight designs are advantageous.

High Temperature Fans

200 F High Temperature Duct Fans come with special heat bearings and a belt drive with increased safety factor.

Tubeaxial Fans

650 F Tubeaxial Fan design involves special belt tunnel cooling system that induces a flow of cooler, ambient air through the belt well and inner tube, cooling the fan’s internal components. Depending on temperature requirements, modifications include high-temperature alloy fan wheel, special drive components, and modifications to provide internal ambient air cooling.

Fans with ambient air cooling systems handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit. The Tubeaxial fan ambient air cooling system is only effective while fan is operating.

Vaneaxial Fans

800 F Vaneaxial Fans are designed to operate continuously at temperatures to 800 deg. F, and include an auxiliary cooling fan that forces air through the bearing compartment and exits out through the insulated belt opening taking away excessive heat from the shaft and bearings. A high temperature shaft seal is also standard on this design.

Fans handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit. The Tubeaxial fan ambient air cooling system is only effective while fan is operating.

High Temperature Fans Specifications

The Canada Fans complete high temperature fans line now include:

– Operating up to 2200 F, centrifugal, axial and plug fan types;
– Pre-engineered and custom made fans for all types of applications with vaiety of impeller types and accessories;
– Canada Fans engineers provide a professional advice and recommend a right fan for every application & oven / plenum design;
– The fan offering provides competitive replacement fans to Garden City, Lau, IGE, Alloy Fabricating fan models; repairs, re-build & balancing;
– Unique high temperature water-cooled motors for operation up to 2300 F;

in the two major types of high temperature fans – centrifugal and axial:

Centrifugal Wheels:

* Multiblade forward curve wheel. This type of wheel is usually specified where there is a necessity for large volumes of flow against low to medium static pressure requirements. The forward curve blade is that it delivers the same volume of air as either the backward or radial blade wheel, at a lower fan speed, which is important due to wheel stresses at elevated temperatures. This fan is the most common type used in all types of heat treatment operations except where a buildup of material on the blades could occur, as wheel unbalance would result.
* Radial Blade, paddle wheel type fans. This type of wheel is usually specified where there is a necessity for medium volumes of flow against medium to large static pressures. The paddle wheel is considered a self cleaning type of wheel. It could be used where there are various materials or dust in the air stream. Due to its structurally strong design, it is used in many heat treatment applications at very high temperatures where maximum fan longevity is desired.

Axial Blade Wheels:

* The axial blade wheel is usually specified where there is a need for very large volumes of flows against low static pressure. Axial wheel like the multi-blade forward curve type wheel could cause an axial fan to deliver different air volumes at the same static pressure, if the total pressure requirement of the fan system was underestimated. This type of fan is ideally suited where a large volume of flow is required with a minimum of duct work and is used extensively for small and large furnaces, such as aluminum annealing.

Fiberglass Reinforced Plastics (FRP) provide the desired non-corrosive quality to the fan blades, resulting the operation of fans even in the very aggressive environment. Lightweight FRP fans also ensure a low moment of inertia, minimum wear & stress on motor, bearing and drive system.

Hollow FRP blades reduce material & installation costs and possibility of damage to the fan & drive during sudden stops. Composite structural design can be tailor made by using glass fibres in various forms (woven mat & rovings) in right direction while moulding the impeller with resin thus imparting the desired mechanical strength by improving its structural stability and enhanced mechanical properties.

Aerofoil design of fan impellers ensures higher efficiency, lower noise levels & less power consumption. The aerodynamically designed impellers of fans, fabricated by composite material can be an excellent alternative to ensure enhanced efficiency & appropriate energy savings apart from a wide gamut of critical advantages.

The FRP fans offer certain critical advantages as mentioned hereunder:

– Optimal aerodynamic design of fan impellers to provide higher efficiency for any specific application.

– Reduction in overall weight of the fan, thereby extending the life of mechanical drive systems.

– Require lower drive motor rating and light duty bearing system.

– Low power consumption resulting in appreciable energy savings.

– FRP fans fabricated by compression moulding/resin transfer moulding technique would have uniform dimensions and consistent quality.

– Lower flow noise and mechanical noise levels compared to the conventional metallic fans.

– Longer life of fans due to improved mechanical strength.

The potential of FRP composite for various applications is very wide. In view of the crucial need for developing indigenous capability in composite technology the main advantage of FRP fans is their utilization and application of composite as an important performance material in various sectors and to improve upon the laboratory-industry linkages towards development & commercialisation.

Ventilator Fans – Methods of Building Ventilation

When straightforward breeze conditioning system is possible, the rate of air velocity method outlined above should be the basic method used. However, there may be rooms or areas within the building that will require special treatment. If so, one of the other methods, such as spot cooling or zone cooling, may be combined with the basic method to achieve the over-all objectives.

Air circulators

Air circulators may be effectively used to boost air velocity through large buildings that have a flow pattern difficult to control. Air circulators are also used to redirect air into occupied areas near floor level. Air circulators are also effectively used in locations where adequate exhaust and supply air fans may be lacking. Air circulation alone may provide heat relief and cooling comfort to individuals in the area. Northern Fan’s Type CABL fan is ideally suited to this application. For many installations, fans like this may be positioned 8′ to 10′ above the floor and at approximately 50′ intervals to obtain a continuously circulating column of air across a room or building. To broaden the column of air, fans should be located abreast of each other 15′ to 20′ apart. Fan locations and positions are easily adjusted to the requirements of the area.

Although an accurate, intelligent calculation of the required air volume for a breeze conditioning system has been made, there are practical limitations in most buildings that may seriously affect the final results. By giving these limitations proper consideration in the planning stage, the system can usually be modified to compensate for them. Some of the more common limitations are listed here.

Air Flow Restrictions due to interior partitions

It is obvious that interior partitions restrict and interrupt the flow of air through a structure. The effect of these partitions on the system must be analyzed and solutions found. In buildings with very high ceilings. the cross-sectional area factor may become unrealistic in calculating the required air volume. In most instances, inexpensive baffles can be installed across the building width to reduce the effective cross-section to an area 10′ or 12′ above floor level. Machinery, raw materials and finished goods that obstruct air circulation. These obstacles, like interior partitions, must be considered and methods worked out to overcome the problems they create to the proper circulation of air through the structure. Frequently, the location of heat-producing machinery will seriously interfere with the preferred pattern of air circulation. This situation can destroy the effectiveness of the system. An alternative plan to overcome the problem is essential.

Another limitation of the very high ceiling or roof is the difficulty of maintaining the air velocity near floor level. The baffle method just described is usually the best way to reconcentrate the air flow along the floor level where it will be effective in providing personnel comfort. In large buildings, baffles may be required at l00-foot intervals to keep air flow near the floor level.

Operations within the area frequently require wall openings or loading doors that will drastically interfere with the desired airflow pattern. In some cases, individuals may open windows that should remain closed to maintain effective air circulation. A remedy for each of these problems is required. For maximum efficiency and economy, a good layout will avoid the restricted intake opening. The type of exhaust equipment normally utilized is most economical and efficient if static pressure in the system is 1/8″ or less. To obtain this condition, air velocity through intake openings should not exceed 1,000 feet per minute, a lower figure is usually desirable.

Industrial Fans Uses and Applications

Fans have helped to create safer and more pleasant internal environments for hundreds of years. The invention of mechanical fans is found in the industrial revolution and the first commercially viable electric fans were made available to the US public early in the 1930’s.

Fan Manufacturing and Ventilation Solutions

Today the technology behind fan manufacturing and ventilation solutions have sky-rocketed to create fans for virtually every use from cooling devices in a server room; to ventilation in a manufacturing plant; to keeping a bathroom clear of damp air.

Generally speaking, fans and their accessories can be divided into 3 main usage categories: domestic use, industrial use and commercial use.

Industrial Fans

Industrial Fans will often have a very robust requirement and it is essential to involve experienced engineers with the installation of such ventilation. Other than just determining whether the fans will be required for air supply or for exhaust functions (i.e.: as an extractor fan) the engineer or installation technician will need to be keenly aware of both the working temperatures of the units as well as any thermal protection qualities of its associated housing or frame.

Some industrial fans will come with controllable speeds which can be very handy in a changeable internal environment, especially with regards to saving on ventilation costs at times when the air regulation needs of an area are reduced. Special features such as built in monitoring and systems integration come in handy when working in a potentially hazardous environment for example when chemicals or volatile substances are involved. Generally speaking, fire resistance and corrosion resistance are both ‘plus’ features for any industrial ventilation setup. Above the ‘plus’ one will need to consider the health and safety requirements of your region such as vibration or noise control and air quality regulations related to worker health.

Commercial Fans

Commercial Fans would not have as robust a requirement but the overall integration of fans into the building structure and management system is key to efficiency. Automatic ventilation in refrigeration units or in rooms that will typically contain many people at the same time will keep areas safe and comfortable. Operational areas such as server rooms (also known as data rooms) and elevators will need to provide adequate ventilation, usually in the form of extractor fans, to remove excess heat generated by the operating machinery which often runs continuously. Commercial ventilation also acts as a barrier to unwanted external influences such as insects, pollution and natural allergens.

Domestic Fans

Lastly domestic fans find their main purpose in providing less costly air quality solutions. There are two ways to cut costs with a domestic ventilation solution. You can invest in a ‘cheap and cheerful’ unit from the beginning resulting in a smaller initial cost or you can install a slightly more costly fan and ducting system with operational features that help you save on heating and ventilation costs in the long run. There are a wide variety of low energy extractor fans and ventilation units are now available for kitchens, washrooms and living rooms. In addition heat recovery units now help you to use the heat from stale air that is being extracted to warm-up fresh air that is being pulled in by your system.
