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.

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

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.

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.

Types of Exhaust Fans

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.

Wall Mounted Exhaust Fan Systems

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.

Ceiling or Wall Mounted 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.

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.

Roof Ventilators

It can decrease make up of heat in the roof spaces; reduce the heat load on the isolation. In turn, you will make save on your electricity bills as the air-conditioning systems will not have to work as hard.

In winter, it decreases the amount of condensation that forms when warm moist air from exhaust fans meets cold surfaces also reduce the amount of corrosion and wood is created due to condensation. It should be installed where no sarking with tile roofs, metal roof deck is used, and when there is evidence of condensation in the attic or ceiling.

How Roof Ventilators Work

Accurate ventilation needs that there be a flow of air into the room and the temperature and humidity should be maintained within a range that allows adequate evaporation of sweat from the skin. It was previously thought that the anxiety, nuisance and laziness often linked with bad ventilation were caused totally by the enhance in the quantity of CO2 and decreased oxygen in the air. There is proof, however, that the effects depend largely on the interference with the mechanism of heat regulation in the body. Lack of air flow and increase the relative humidity and temperature prevent normal evaporation of perspiration and heat loss from the skin surface.

Roof Exhausters

Roof exhauster is essentially a simple hole in the roof with a cover to protect from rain and wind to avoid interfering with its operation. A useful addition is a fan stirring the air or gas to move from one place to another. Mechanical fan blades of bearing is used for ventilation, in manufacturing, in winnowing grain, to remove dust, cuttings or other debris, or plans to offer a fire. The addition of distribution channels for the fan and a system to force air into the building provides greater efficiency. The outputs are designed for maximum mixing of air and move large amounts of air at low speed so that the temperature of the layers is removed. The factories are equipped with unusual suction hoods for dust boxes located smoke and heat.

Essential Uses and Attributes of Quality Roof Ventilators

Deep mines, underwater tunnels and other underground environments and underwater systems require development of mechanisms for maintaining air flow in a healthy state. Life for those working or traveling in these areas depend on a constant supply of fresh air, not only must the systems are very effective, but it should be possible in an emergency in case of failure of the device running. Derived from studies of the problems of ventilation systems is the development of methods of air conditioning heat pump is a device that the reversible mechanical work to extract heat from a cooler place and deliver heat to a warmer place. Heat is supplied to a warmer place, about the sum of the initial heat and work.

These systems, unlike conventional methods of ventilation, independent of outside weather conditions and can be stored indoors, temperature, humidity and healthier environment, and the air is free of dust and other harmful substances. They achieve this, however, significant energy costs.

A trustworthy ventilation arrangement that can function throughout a fire is both fundamental and significant. It prevents smoke logging, allows people to escape quickly, reducing damage to property and contents and enables firemen to attack the fire without hindrance. These power roof exhausters have the added advantage that the normal day to day ventilation and in many cases can also be equipped with working channels for use in multi-storey buildings.
