Radial Blade Fan – Canada Fans Industrial Blowers & Fans

Industrial Fans & Noise

The important factor to consider is the fan’s blade pass frequency, which is a pure tone produced when the blades of the fan wheel (impeller) rotate past the housing cut-off sheet in centrifugal fans, or the turning vanes, in axial fans. The blade pass frequency is calculated by multiplying the number of blades times the rotating speed in revolutions per minute. If this frequency matches the natural frequency of the ductwork, it can excite the ductwork, which can cause it to resonate, thereby increasing the noise level. Because of this possible increase in sound, and because certain pure tones are irritating to people, the sound output of the blade pass frequency should be investigated when sound reduction is desired. The next factor to consider is the fan design. Generally a fan operating at peak mechanical efficiency will produce less noise, because high efficiencies result from minimal air turbulence within the fan.

The sound generated by some fans can be a potential hazard to personnel in close proximity to the fan, and the sound can be transmitted, via the ductwork connected to the fan, to all areas serviced by the fan. Because of these concerns, fan manufacturers publish sound ratings for their products to serve as a guide for selecting fans to meet sound specifications, and to assist acoustical consultants in predicting the total noise levels in specific environments. This article provides basic information to help understand fan sound ratings and how to apply them. Like any mechanical device, fans generate sound, which emanates naturally from the turbulence of moving air, the mechanics of moving parts of the fan, and from vibration.

Air turbulence within the fan increases the sound coming from the air movement. The noise resulting from air turbulence is a major factor in the sound levels of a fan in a specific application. Further, duct work can transmit this turbulent noise to all areas serviced by the fan. Factors contributing to air turbulence include the resistance to flow, flow separation along fan surfaces, and shock related to abrupt changes in the direction of airflow, pressure, or velocity. A lower noise level can be achieved by reducing air turbulence. This can be done by considering several factors related to air movement when selecting fans.

Industrial Centrifugal Fans Design

There are four basic centrifugal fan wheel designs – forward curved, backwardly inclined, radial, and radial tip – and a variety of axial flow wheel designs. Each wheel design has unique sound characteristics due to the way they handle air, and the efficiencies they can achieve. Fan speed does not always determine which fan will be quieter. For example, centrifugal fans have higher amplitudes at lower frequencies, while axial fans exhibit higher amplitudes at the higher frequencies. The amplitude of the blade pass frequency on an axial fan is higher and more pronounced than on backwardly-inclined fans, and commonly will have amplitude peaks at multiples of this frequency.

Backward Inclined Fans

Of the four centrifugal designs, the backwardly inclined fans are the most efficient, and therefore, the quietest. Those with airfoil-shaped blades offer the highest efficiencies, for clean air environments, while those with single-thickness blades can be used in applications where light dust or moisture is present, although the efficiencies are somewhat lower.

Axial & Vaneaxial Industrial Fans

Certain types of axial fans offer the next highest efficiencies. An excellent example is the Vaneaxial fan that uses airfoil shaped blades in an in-line flow design. This fan is used to handle high volumes of clean air at low pressures, which is a typical ventilation application.

Radial Blade Fans

Radial fans are typically low efficiency, open designs for special purpose applications, such as bulk material handling, or exhausting / supplying lower volumes of air at higher pressures. A radial fan will be much louder than a backwardly-inclined fan operating under the same volume and pressure conditions.

Radial Tip Fans

Radial Tip fans, commonly used to handle larger volumes of air that contains particles or material, exhibit sound characteristics similar to the radial fans. The sound spectra of radial and radial tip fans contain amplitude spikes at various frequencies, and a noticeable spike at the blade pass frequency.

Forward Curve Fans

The forward-curved fan design operates at speeds that are much slower than the other fan types, which results in lower noise levels from mechanical operation and vibration. However, because of its modest efficiencies, a forward curved fan may be noisier than a backwardly-inclined fan when operating at comparable volume and pressure. The sound spectrum of the forward-curved fan shows a slower rate of reduction in amplitudes than the other centrifugal types, and because of the large number of blades, the blade pass frequency occurs much later in the spectrum and is not predominant.

Industrial Fan Components

The moving components of the fan – the motor, bearings, and drive – produce sound. This too can be transmitted through the system via the fan structure or shaft, or when these components are in the airstream. Motor sound will vary with speed, enclosure, electrical characteristics, and even the manufacturer. Antifriction bearings can be used to reduce bearing noise, and proper drive selection will reduce the likelihood of belt hop, or slap. Of course, proper maintenance must be employed to keep the moving parts running smoothly, and quietly.

Excessive vibration can significantly add to the overall noise level of an installation. This will occur if the fan or any of its components are not adequately balanced, if the fan is installed on an insufficient foundation, or if the fan is not properly isolated from other system components. For example, it is not uncommon for the fan’s support structure or ductwork to have a natural frequency at the fan’s operating speed or blade pass frequency, either of which can cause the system to resonate at that frequency, increasing the sound levels, and the possibility of damaging the installation. These risks can be eliminated by changing the speed of the fan, installing appropriate isolation, and / or detuning of the fan or affected system components.

dBA is a useful measurement for evaluating the overall noise level at a particular location, but this measurement takes into account all of the sound sources affecting that particular location, which include the sounds from all equipment in the area, natural sounds of the environment, and from other environmental factors. Some of these factors are the current physical properties of the air such as temperature, humidity, and pressure, whether the location is outside or inside, the size and material of the room. All of these affect the sound pressure experienced by the listener, and recorded by the sound level meter.

Published fan sound power ratings and corrections only reflect noise created by air turbulence within the fan. Because of the infinite variables, mechanical noise and vibration noise are impossible to accurately predict, and are not included in the rating.

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

Selecting an Industrial Fan

The air delivering capacity of axial flow fans ranges from 100 to 500,000 cubic feet per minute (3,000 to 15,000 cubic meters per minute). Impellers usually have blades with airfoil cross-sections.

Axial Fans

In an axial fan, the effective progress of the air is straight through the impeller at a constant distance from the axis. The primary component of blade force on the air is directed axially from inlet to outlet and thus provides the pressure rise by a process that may be called direct blade action.

The blade force necessarily has an additional component in the tangential direction, providing the reaction to the driving torque : this sets the air spinning about the axis independently of its forward motion.

As compared to curved sheet blades, aerofoils can apply greater force to the air, thereby increasing maximum pressure and can maintain better efficiency over a wider range of volumetric flow. Also by increasing the thickness & curvature of the inner sections, the blades can be made stiffer, this limits flutter and allows the impellers to be run at higher speeds.

Selection of a a right fan one should consider such factors like cost optimization, power rating & noise levels govern the selection of a fan suitable for a given application. Various combinations are possible to meet any given duty or operating requirements for best performance, lesser noise, power and cost characteristics.

Once the volume of airflow and the static pressure of the system are known, it is possible to specify a fan. The governing principle in fan selection is that any given fan can only deliver one flow at one pressure in a given system. To select a fan one must consider the following parameters:

– total airflow required

– total operating pressure

– fan installation space

The fan efficiency is defined as the ratio of air power (output) to shaft power requirement (input). An optimally designed fan impeller with improved aerodynamics requires less shaft input power for desired delivery of air volume with total pressure rise as per the system requirement. With reduced shaft power requirement, there is a commensurate reduction in energy consumption.

Thus the fan efficiency is directly contingent upon selection of fan and the operating point relevant to the system resistance.

The way fan impellers (blades or rotors) are designed, the amount of air they can move decreases as the pressure they are working against increases.

The airflow vs. pressure information for a particular fan is called the fan performance data. The performance of a fan depends on the size, shape & speed of the impeller. The fan performance data is essential for selecting fans as per the desired airflow and system pressure.

Most fans are tested using procedures specified by Air Movement and Control Association International Inc. (AMCA), Illinois, USA. The fan under test is mounted near the outlet of the test rig and air in-flow through the rig is varied by the movable gate assembly situated at the other end of the test rig.

The airflow through the rig is determined by measurement of the pressure differential and simultaneous readings are taken of the static pressure developed by the fan, air velocity at the exit side, power consumed by the fan driving motor etc.

Fan performance curves and data show how much pressure and airflow a given fan can produce at a given speed. This data is based on the system resistance (pressure) occurring away from the fan. Fan performance curves are developed by fan manufacturers based on the testing of a prototype fan fabricated based on the theoretical design.

The axial flow fans are widely used for providing the required airflow for heat & mass transfer operations in various industrial equipment and processes. These include cooling towers for air-conditioning & ventilation, humidifiers in textile mills, air-heat exchangers for various chemical processes, ventilation & exhaust as in mining industry etc. All the major industries use large number of axial flow fans for operations, such as :

– Power generation

– Petroleum refining & petrochemicals

– Cement industry

– Chemicals & pharmaceuticals production

– Fertilizer production

– Mining manufacturing

– Humidification in textile mills

– building Ventilation, etc..

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.

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.
