Commercial Extractor Fans

Today there are a wide range of commercial extractor fans available on the market to cover just about every application imaginable; from large commercial applications, such as restaurant kitchen extractor systems, to quiet airflow systems that are virtually silent in operation.

While a commercial kitchen extraction system, commonly made in stainless steel can cost several thousand pounds to buy and install, a large vent-axia through wall extractor fan may be fine for a small hot food business such as a shop making toasted bacon sandwiches.

The new quiet airflow extraction systems are proving popular as they have a high airflow, yet can barely be heard running. This helps keep environmental noise down, and this is often important in an office workplace.

Commercial Inline Fans

Commercial in-line fans are available that sit above the ceiling, often some distance from the room they are actually extracting the air from. They are connected to vents in the ceiling by ducting, which then connects to the inline fan, and then expels the air through more ducting to a grill in an outside wall.

This type of fan has to be used in certain “classes” of environment by law, whereby no electrically powered unit can be placed within a certain distance of damp areas, such as shower rooms as an example.

When buying a commercial extractor fan, you will have to take more into consideration than when purchasing a domestic extractor fan. The reason for this is that whilst a domestic fan may be cheap to buy and install, and can be replaced at a low cost if it breaks, the same cannot be said of a commercial extraction system.

Large Commercial Extractor Fan Installations

Most large commercial extractor fan installations will cost several thousand to buy, and will need professional installation. So given the investment you may make in one, you need to be buying with a reputable supplier, as you may be installing it in an environment where you may have to stop work if the extractor fan system breaks down, such as in a commercial kitchen.

If this happens, you need to know that someone can come out and fix your extractor fan very fast, as if you have to close your kitchen down, you will be losing money until it is fixed. So you need to do some research about the company you are buying your fan from, and ensure that they can provide a fast call out, and that they carry sufficient spare parts.

Power Roof / Wall Exhausters

To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and / or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure. The most effective way to incorporate wall or roof exhausters into a system will be discussed below. A large number of buildings use exhaust fans and/or power roof ventilators to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure. This condition can create problems in many areas of operation. Examples are: (1) reduced efficiency of exhaust systems that are working against each other; (2) down drafts in flues, that may extinguish pilot lights and cause explosions and tire; (3) severe drafts around windows, doors and other locutions when air seeks to enter the structure. The solution to problems of this kind is usually found in the use of supply fans or “make-up” air ventilators. During the hot weather period, these fans become a valuable source of fresh, cooler, outside air to replace the superheated air being exhausted. If they arc correctly sized and coordinated with the exhaust fans, an effective ventilation system may be achieved.

Industrial Fans for Ventilation

A work stoppage or strike may occur if the problem of personnel discomfort is unresolved. The benefits from a solution to such a situation are enormous. In plants where there is a high density of employees and many manual operations involved, an improvement in the environment can produce substantial benefits in terms of increased production, reduced errors, and a decline in complaints and absenteeism among employees. In other circumstances, the attentiveness of an audience or student group may be a factor that spells success or failure for the project. There is a Buffalo Fan case history where a high ambient temperature had actually reduced the capacity of a big power turbine. To obtain rated performance by the machine, an improvement in the room ventilation and cooling system was necessary. When this was accomplished, the plant management was amazed to find an equivalent improvement in the efficiency of the employees who were required to work in this same environment with the machine.

Roof / Inline Exhaust Fans

If the exhaust and supply air requirements of a building have been carefully engineered and installed, and there continues to be a high instance of worker discomfort, the problem usually relates to the matter of air circulation. Typical examples of worker discomfort are found in areas where exhaust fans are roof mounted and air supply is through windows and wall openings. Air flow is generally from the window opening to the nearest roof exhauster. The cooling effect on the individuals in the area is negligible. To be effective, air flow must be at or near floor level. In this way, occupants obtain maximum benefit from the fresh, cooler air; they receive the added comfort of air circulation over their bodies and they are not adversely affected by the superheated air being exhausted from the building.

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.

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.

Vaneaxial Fans

Canada Fans tubeaxial fans, vaneaxial fans and wall propeller fans are found throughout the world operating in industrial processes where performance, reliability and maintainability are of paramount importance. Ranging in diameter from 15 inches to over 84 inches, and with a variety of impeller designs, control systems and layout options, they form a comprehensive series of axial fans to satisfy virtually all industrial applications. The majority of Canada Fans fans can be grouped into four broad categories: with fixed pitch props, with variable pitch props and with controlled pitch props. Canada Fans fans are capable of moving from a few hundred cubic feet per minute, to heavy duty adjustable pitch props with capacities up to 900,000 CFM and with static pressures from 0 ” Water Gauge (WG) to 20″ ” WG.

Heavy Duty Axial Fans

Canada Fans Heavy Duty Axial fans are available with adjustable pitch blades are capable of more air delivery for the same horsepower. Efficiencies exceeding 70% are common. The primary reason for increased efficiency is Canada Fans’s unique blade design. The entire length of the blade surface generates air flow, not just the tip alone. The air flow is uniform all along the blade.

Axial Flow Fans

Canada Fans axial flow fans are best buy for many industrial air moving jobs. Generally, an axial costs considerable less than a quality centrifugal fan delivering the same volume and pressure. They cost less to install since they are lighter, requiring minimum structural support. They can be duct mounted, taking up little space. Direct drive models mean faster start-up and the abscence of V-belt drive and fan bearings lowers maintenance costs.

Vaneaxial Fans with Adjustable & Controllable Pitch

Adjustable and Controllable Pitch Vaneaxial Fans feature an adjustable pitch blade wheel that permits matching your pressure/volume requirements exactly, and lets you make on-the-job adjustments to compensate for system changes.

Tubeaxial Fans

Canada Fans Tubeaxial Fans have fixed blade wheels in capacities up to 100,000 cfm and to 5″ total pressure.

A new high pressure (up to 1.5″ WG) small vaneaxial Series VA fan is an ideal booster fan for prolonged ducts. Unlike inline centrifugal ventilator, that also generates rather high pressure, the air comes out not from a peripheral outlet ring area, but distributes evenly across its outlet opening like in true axial blowers.

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.
