Blower – 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 Ventilators – High Temperature

One of the most critical components of the fan are the bearings. So naturally if the bearings are kept out of the hot airstream they are less susceptible to the effects of the high temperature, and therefore the air temperature can be higher than the limiting temperature of the bearings. Inline fans inherently have drive components in the airstream. In such cases, the unit can sometimes be designed so that cooler outside air is drawn over the drive components, providing some additional cooling. Incorporating this type of external cooling is one of the main reasons Northern Fan medium pressure tube axial inline fan (TBI) can be used for high temperature exhaust applications. There are, however, some arrangements that donÕt allow for the incorporation and benefits of external cooling. For instance, fans in arrangement 3 have the wheel suspended in-between the two bearings. Consequently, one or both of the bearings will always be located in the air stream. Similarly, direct drive fans are limited by the maximum operating temperature of the motor, since the motor is located directly in the hot air stream. That is why most often high temperature exhaust fans are required to be belt driven units; typically the motor is the temperature-limiting component of the unit when it is installed in the airstream. Other than the installation location of the bearing within the fan assembly, other critical points to consider include the type of lubrication in the bearing, as well as the construction of the bearing itself. There is a seemingly endless list of lubricants available for most any application, but the appropriate lubricant can add considerable life to bearing operation. In addition, high temperature bearings can be constructed with inherent construction modifications, such as a larger grease cavity to hold more lubricant.

Industrial Fan Design

Another common variation to the standard fan design is the addition of insulation. The bearing mounting plate, bearing cover and belt tube are the most likely components to be insulated for a high temperature application. Northern Fan automatically includes insulation for these components on all fans specified with either HT Option III or HT Option IV.

Exhaust Fans

It is important to understand that emergency smoke exhaust fans are designed to operate effectively for the temperature and time limits stated as long as the power supply to the fan is not terminated. Since they are not designed to sustain higher temperatures for continuous use, exposure to the extreme high temperatures caused by a fire likely would destroy some or all parts of the fan once the time design limit has elapsed, rendering it incapable of future operation.

High Temperature Fans

Fans that are built for continuous high temperature ventilation have many of the same construction features and options as those built for emergency smoke exhaust. For example, both are typically constructed of higher temperature ferrous materials, have high temperature bearings, have the motor and drive installed either out of the airstream or with some type of additional cooling capabilities, and incorporate some heat shielding or insulation. There are, however, some distinct differences between the fan designs for the two application categories. One of the most common applications for which continuous duty high temperature exhaust fans are specified is commercial kitchen ventilation.

Fans that are specified for continuous operation at higher temperatures need to be carefully selected taking into account air density corrections. Although a fan will move the same amount of air at two different temperatures, the static pressure and horsepower requirements can change drastically as the density of the air varies with changing temperatures. For example, if a fan moves 3,000 CFM at 70 F it will also move 3,000 cfm at 500 F. However, since the hotter air weighs much less than the 70 F air, the fan will require less brake horsepower and will create less static pressure.

There are also some accessories and construction options that are incorporated into high temperature process fans to increase the limiting temperature. For example, a heat slinger can be installed on the shaft between the fan housing and the inboard bearing. A heat slinger is an aluminum disc that absorbs and dissipates some of the heat conducted along the shaft before it travels to the bearings. Many heat slingers incorporate fans that promote additional inboard bearing cooling because it circulates air with every rotation of the shaft.

Another common construction technique is the use of a heat gap. A heat gap is a physical gap between the bearing support structure and the hot fan housing. This separation slows the process of heat conduction to the bearings and drive components through the housing and support structure. An expansion bearing should be installed where the fan shaft is predicted to conduct enough heat that it could expand to a length greater than that of the structure to which it is secured. This allows for expansion of the shaft within the bearing due to the higher temperatures.

High temperature applications can be found in many different areas of the air movement and control industry. It is important to remember that one high temperature fan design is not suited to all applications.

Industrial Ventilators for Ventilation

Industrial ventilation is of paramount importance to ensure the safety and well-being of employees. In industries where employees are subjected to dangerous chemicals, vapours and gasses on a daily basis, effective industrial ventilation can mean the difference between life and death. The basic concepts behind industrial ventilation are quite simple, but for it to be effective, the ventilation system needs to be installed by an experienced engineer.

Industrial Ventilation Methods

Industrial ventilation is a method of controlling employee exposure toxic chemicals, volatile airborne substances and flammable vapours by removing the contaminated air and replacing it with clean, fresh air. Used in a variety of different industries where poisonous vapours may be a problem, industrial ventilation is most often employed to remove welding and solvent vapours, oil mists and poisonous or volatile dust.

But, industrial ventilation may not always be necessary. True, it should be preferable for the continued health of your employees, but regulations suggest that industrial ventilation only becomes compulsory when:

•the levels of contaminants exceed regulated levels;
•the lower explosive limit of flammable vapours is exceeded; or
•when the oxygen concentration in an area drops below 19.5%.

Industrial ventilation should also be considered before respirators. Not only is the system easier to maintain, but, in the long run, is a much more cost effective method of air purity control.

Industrial Ventilator Options

There are a number of industrial ventilation options available depending on the circumstances of your industry’s circumstances. The most basic is indoor quality ventilation that aims to provide fresh air throughout a building as part of the existing ventilation system. This option is primarily used in offices but can be effective in small industries where the concentration of contaminants is low.

Easy to maintain and inexpensive to set up is dilution ventilation. This form of industrial ventilation uses large and powerful exhaust fans to extract contaminated air and to draw in clean air. It is very effective in clearing flammable vapours but is less effective for metal fumes or large concentrations of highly toxic materials. Depending on where the industry is located, the incoming air may require a lot of cooling or heating before it can be introduced into the industrial ventilation system, increasing the cost of using the system.

Dilution Ventilation Principles

Dilution ventilation uses the simple principles of displacement and dilution to function. Some of the contaminated air is removed and replaced with large amounts of fresh air. The concentration of the contamination is effectively lowered, making it safer for people to work in the area.

A more localised industrial ventilation system is local exhaust ventilation. This system captures the contaminations at the source and expels it before it has a chance to disperse into the air. For highly toxic contaminants or high concentrations, this industrial ventilation is probably one of the best. It does not require large amounts of fresh incoming air since the exhaust of contaminants is localised. This effective ventilation comes at a higher cost and more frequent maintenance, however.

Local Exhaust Ventilation

Local exhaust ventilation works like a vacuum cleaner forcing contaminated air to move from a high concentration to a low concentration. It is perhaps one of the most effective industrial ventilation systems because it removes the contaminants at the source before it has a chance to spread.

There are effective industrial ventilation systems available for any industry. Some are simple to use, like dilution ventilation, while others are specifically made for highly toxic environments, like local exhaust ventilation. Whatever the decision, as long as the industrial ventilation keeps your employees safe from the contaminations of the substances they work with, it is doing its job.

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 Building Ventilation

Based on the objectives and funds available, one can now consider different alternatives for industrial building ventilation and select the best method to use in calculating air volume requirements. A description of these methods follows. This is a time-honored approach to a determination of air volume requirements. It is based on the theory that a complete change of air in a room or building should be made at a certain time frequency. The rate selected is frequently an arbitrary decision. It may be based on experience with similar installations or may be established by a health or safety code. Many fan manufacturers have published charts that show recommended rates of air change for typical installations. Although the rate of air change method of calculating air volume has been used for many years, Buffalo Fan engineers have found it unsatisfactory except in relatively small buildings or rooms. For jobs that involve personnel comfort. this method is not recommended if the building is over 50,000 cubic feet in content or more than l00′ in length.

Considerations for Building Ventilation

The volume of air required to operate a ventilating and cooling system is a very fundamental requirement. Before air volume is estimated or calculated, careful consideration should be given to the following factors. Be sure that the decision you make will accomplish the most important objectives or will overcome the most important problems. This should be the overriding consideration in the selection of a system of ventilation. Availability of money to finance the system is a factor that must be considered early in the planning stage. The funds available will affect the objectives you set and will influence the system of ventilation selected to meet the objectives.

CFM per square foot of floor area method

CFM per square foot of floor area method: this method of calculation is a modern adaptation of the rate of air change formula. Total air volume (cubic feet per minute) is determined by multiplying the total square feet of floor area by an arbitrary CFM per square foot figure. The figure selected may be as low as 2 CFM or as high as 12 CFM per square foot. Four CFM per square foot has been recommended as a minimum for summer ventilation of large assembly type operations. This method of calculation, like the rate of air change method, is likely to produce unsatisfactory results in many cases. Failure to control air distribution and air velocity can be a major weakness in the whole concept. Selection of a CFM per square foot figure should be based on experience and a proven method of air distribution.

Rate of air velocity method

Rate of air velocity method: This method of calculating air volume needed for a system is highly recommended by American Coolair. A breeze conditioning system can be highly effective in providing personnel comfort in hot weather if the recommendations outlined below are observed. It has been determined from field experience that an average air velocity of 150 feet per minute (FPM) to 200 FPM is usually sufficient for personnel cooling under summertime conditions. The CFM required to do the job is calculated by multiplying the cross section of an area through which the air is to move by the desired velocity. This is expressed in the following formula.

Factors Affecting Average Air Velocity

As building size increases, there are factors that will affect the average air velocity through the cross section of the building. The longer the building, the greater the amount of air leakage from windows, doors, elevator shafts, etc. To offset this air leakage, air velocity should be increased. This is done by relating the calculated velocity to the length of the building. The results will provide an effective velocity of approximately 150 ft./min.

Industrial Ventilators

In some buildings. it is not possible or practical to install a complete ventilation system. In such situations, zone cooling may be effectively used. The problem is similar to a spot cooling application, but usually involves a relatively larger area. Effective zone cooling may be accomplished by use of air circulators. See Air circulation below. A very satisfactory zone cooling method is the use of supply-type PRVs to flood the problem area with fresh, cooler air. The adjacent drawing and zone cooling table illustrate the capacity of several American Coolair PRV models to effectively cool an area. The figures are based on discharge of air approximately l5 feet above floor level.

Mixed Flow Fans

Mix flow fans combine characteristics of both axial and centrifugal fans, and in the Canada Fan design the impeller resembles a fixed pitch axial fan. Canada Fan has two ranges of mixed flow fan: one heavy duty, ideally suited for handling dust-laden gases, and a compact range that gives higher pressure rises than can be obtained from similar sized axial fans.

Heavy Duty Mixed Flow Fans

Canada Fan heavy-duty mix-flow fans are extremely robust, with plate blades that are ideal for handling dust-laden gases at elevated temperatures. Though a mixed flow fan is not as efficient as other types and the operating range is more limited, fan performance is less degraded by erosion or corrosion. Should repairs be needed the blades are easily welded. Heavy duty mixed flow fans are available with flows from 200 to 1000 m3/s and pressure rises up to 8 kPa.

Compact Mixed Flow Fans

Canada Fan in New York compact mixed flow fan is a fully ducted, in-line machine that has a non-overloading power characteristic. It is capable of operating throughout its pressure / volume curve without stalling, even at zero flow. This fan is ideally suited to applications where space is limited and, for example, is commonly used for ventilation on offshore oil platforms. Its robust design maximises reliability and, with anti-spark features, it is suitable in zone 1 hazardous areas. Belt and motor drive options are available. The range can produce flows up to 80m3/s at pressures up to 3 kPa.
