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 Extractor Fans

Industrial extractor fans come in a wide variety of shapes, sizes, and strengths so it can be difficult to choose the best one for your restaurant kitchen. There are roughly seven different sizes that are available from 315mm to 630mm which can be mounted in a few different ways. Many businesses prefer the axial style of fan as it can be used for a wide range of applications. This article will discuss these machines and hopefully make your choice of fan a bit easier.

One of the common drawbacks of industrial extractor fans is how loud they are. This can be such a problem that most restaurant managers choose to run them only when the amount of steam, smoke, and pollutants in the air reaches an intolerable level. However, there are some high end models that can run in a Quiet Mode that doesn’t make that much noise at all and even can be run all the time if you choose. You may even want to run the fan a bit after your staff has finished for the day in order to clear up any residual pollutants that may remain in the air.

If you are currently looking at the different options of industrial extractor fans you have available, you will have to decide whether you would like a model that uses ducts or one that uses filters. The former choice is the most efficient as it can take the polluted air directly out of your building and replace it with clean air. Your other option, the filtered models, do not do as well because they will recycle the same air within your building only they run it through a charcoal filter first to make it cleaner. While a ducted model is preferred in most situations, they can be a bit more on the expensive side. Not to mention, you may not have the space necessary to fit the ducts.

It is important that you find industrial extractor fans that have been built to last. Therefore, try to find a model that is built from steel as this is a durable metal that is sure to last. Also be on the lookout for one that is coated in corrosion proof paint and has steel wire guards as well for optimum protection. It is also a good idea to pay special attention to the kind of motor each model features. Try to find one that is lightweight, but works well and is built to last.

One final thing you will have to take into consideration is how you will install your fan. You will find that most axial industrial extractor fans may be installed in various ways such as:

– Mounted on the wall with special brackets

– Placed freestanding in the center of the room

– Hung from the ceiling with chains

– Inline with your ductwork

Industrial Exhaust Fans

The practical designs of modern homes are more focused on energy conservation. Making a home practically air-tight reduces heating requirements thus saving on electricity costs. This may be a great way to save money and help the environment, but it also leads to poor air circulation inside the house. Poor air quality can lead to a variety of cardiovascular diseases, ruined paint and damaged furniture which is why it is important to have good air circulation inside the home. The best way to do this is to install ventilation exhaust fans.

Exhaust Fan Systems

There are many different types of exhaust systems and getting an idea of how each one works will give you an idea of what type will be the best for your home. Different sized homes will have different ventilation requirements. Larger homes will require a variety of ventilation fans to keep the air from getting stale.

Ventilator Fans

The most common types of ventilation air purifying fans are wall mounted, ceiling mounted, inline fans, combination, exterior remote mounted and kitchen range exhaust fans. It is best to have ducting installed in areas where a visible fan would not blend in well. Areas like the living room, dining room, den and bedrooms would be good places to have ducting installed. Stale air runs through the ducting and exits the house via an exterior fan that expels the air outside, or busing using inline fans that are contained inside the actual ducting.

Wall & Roof Exhaust Fans

Kitchens, attics, laundry areas, bathrooms, garage and storage areas can be installed with either ceiling mounted or wall mounted exhaust fans if the area is situated beside an exterior wall.

Ventilator Exhaust Fans for the Home

It is important that all the areas inside a home need to have air circulation so that pollutants, pathogens or even humidity does not accumulate and lead to costly repairs or health problems. Be sure to select ventilation exhaust fans that are suitable for each area of the home.
