Industrial Screw Blowers

Industrial Screw Blowers

Industrial standard ISO-1217 requires the performance of the blower to be measured at the blower outlet. This is a far more accurate indication of the performance of the blower and clearly qualifies the air volume that is available to the aeration system. That is the reason why, for instance, our company provides data for its low pressure screw blowers’ in line with the ISO1217 standard, which requires the performance of the blower to be stated as FAD (Free Air Delivery) – the actual volume of air at the
blower outlet.

From an operational standpoint, it may not always be appreciated that when comparing the energy efficiency of different blower technologies the performance data may not be presented in a comparable manner. For example, lobe blower performance data is commonly offered by indicating the air intake flow volume and the energy used at lobe element shaft, not the actual volume of air the blower package delivers – the net usable air – and not the energy consumption including all the blower package power losses.

This anomaly is all the more surprising when it applies to waste water aeration process operations. In order to maintain the desired oxygen level within the aeration lanes, the precise volume of the aeration air being supplied by the blowers is a critical factor in sustaining the aerobic process. It is for this reason that the latest revision to the Water Industry Mechanical and Electrical Specifications (WIMES) for low pressure blowers has included measuring the blower performance according to the ISO 1217 standard, reflecting the evolving needs of the water industry.

From a technical perspective, the lobe blower has to work harder and therefore less efficiently because the delivered air is compressed externally and depends on back pressure from the connected pipeline (and from water resistance in the aeration tank) to maintain the required air flow and pressure. By contrast, the rotary screw type blower demands less energy because the internal compression concept offers higher efficiency. This becomes even more significant when there is a variable aeration demand; the screw blower exhibits a more consistent volumetric efficiency derived from the design of the rotor elements.

When comparing blower technologies a true package power evaluation should be made. The factors to be considered should include the pressure drops within the blower, transmission losses: belt drive compared to direct drive, motor efficiency and, of course, the air volume at the blower outlet versus the total package power input.

On face value, the lobe blower may appear to offer plant operators a simple, low cost, basic option for low pressure air applications. The reality is that in a low carbon economy many industrial applications can benefit from improved performance and significant energy savings through the replacement of conventional lobe equipment with innovative and sustainable, screw technology solutions.

The increased emphasis on the ISO 1217 standard in providing flow figures from a blower will ensure that operators are provided with a truer picture of blower efficiency and the FAD volume of air that is supplied to their processes.

Centrifugal Blower

Centrifugal Blowers

A centrifugal fan is a blower designed to move air or gases in a confined area. The centrifugal blower has a number of blades mounted around the hub, which turns on a shaft that passes through the housing. The gas enters the side of the fan wheel and by use of centrifugal force (hence the name) accelerates over the fan blades. A centrifugal blower is usually used in factories or large open places that need air flow.

High Temperature Fans & Blowers Applications

Tough applications mean tough fans and blowers by Northern Industrial Co. Northern Industrial is a world wide distributor of industrial process ans OEM fans and blowers, as well as fan / blower components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. Canada Blower also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing. High-efficiency impellers result in low power consumption, operating costs, and quieter operation. All metal hardware is completely sealed from exposure to corrosion by incapsulating into FRP or plastic; the steel support frame and motor base are powder coated with a corrosion-resistant finish. In addition to being highly resistant to chemical corrosion, PP fans are self-extinguishing and will not support combustion.

This could be an underground carpark, a gymnasium or any other open space with static air. There are many different centrifugal blowers on the market today and choosing one will depend on a number of factors.

Centrifugal Blowers & Fans Blades

The centrifugal blower has a number of blades mounted around the hub, which turns on a shaft that passes through the housing.

A Centrifugal fan can come in three different types of fan blades. They can come with forward curved blades, backward curved blades and straight radial blades. The type you need will come down to what the conditions are within the area in which you intend to use the device.

When inquiring about purchasing a centrifugal fan you will more than likely need someone from the company in which your purchasing the fan to come and take a look at the conditions the fan will be placed and also to check what kind of air pressure there is within the area.

Centrifugal Blower Size

The size of the area in which the centrifugal blower is to be used will obviously play a major part in the decision of how large it needs to be and how much air it can actually blow through the area. There are many different sizes that you can get to cover any area but depending on your circumstances you may need more than one to do the job adequately.

The type of air that is in the premises will also play a large role in which type of Centrifugal Blower you need. If the centrifugal fan is to be used in an area where the air conditions are standard then no adjustments will need to be made to the actual fan itself. On the other hand if you are going to operate the fan in other types of air density then adjustments can be made to the static pressure and brake horsepower.

Centrifugal Blower Placement

Another point to be made when you are interested in purchasing a centrifugal blower is where you intend to put it. There are many different styles of centrifugal blowers, they include roof and ceiling ventilators, pressure and volume blowers, duct fans and blowers or freestanding fans and plenum fans.

There is obviously an advantage with freestanding fans as you have the opportunity of moving it to different areas of the building / factory, which is an advantage. If you do have it mounted then it is out of the way and not taking up valuable room. Most Industrial fans come with a safety guard on them now which is made so that no human appendages can accidentally go into the fan. Most centrifugal fans come with an electric motor although they do make ones now which run off an generator also. This is a huge advantage if there is a power failure within the premises.

Most industrial fans make some kind of noise but with a lot of the new models being released now the noise level is minimal. Some can make more noise than others but this depends on the size of the fan and also the conditions which it is working in.

High temperatures, corrosive gases and demanding operating conditions are commonly associated with processing these materials. As a leading supplier for the metal and mineral industry, Northern Fan provides the fans used in all stages of production including conveying, drying, classification, dust collection, pollution control systems, as well as fans for pressure / high volume applications.

Industrial Blower Uses

The Food & Beverage Industry is comprised of wide variety of businesses that require fans for the cooling, drying, ventilating, packaging, and other process applications. Northern Fans are used in the conveying, drying and forming of animal feeds that allow for large scale production of beef, pork, dairy products, and poultry and eggs. The process of getting raw bulk grain materials from the farm to market also requires the use of fans for collecting, drying and properly storing food products. When storing fruits, vegetables and other temperature and humidity sensitive food, Northern Fans play a key role in moving refrigerated air in these precise climate control environments. Manufacturing bottles and packaging for the food and beverage industry require many fan types for numerous processes. Driven by demand, the ethanol industry is one of the first renewable fuel options for energy independence from fossil sources. The process of converting feedstock to ethanol requires a variety of fans from Northern Fan’s comprehensive line of products. This process involves dust collection at multiple points, negative lift systems for material transfer, dryers for byproduct processing, waste heat recovery, and storage ventilation.

Northern Fan manufactures a wide range of fans and blowers for the paper industry. Due to chemical laden air and elevated temperatures associated with the digesting, bleaching, and cooking processes, special materials of construction, such as stainless steel, FRP, and special coatings are required. After the pulp is processed and prepped for the paper production, paper machines utilize our high pressure, high volume fans to provide supply and exhaust air to all stages of production from the wet end to the winding trim systems.

Industrial Blowers & Fans Applications

The recycling industry has diversified and matured in recent decades, resulting in its greater demand for high quality air moving equipment. Northern Fans and blowers are used for delivering the proper air performance for many recycling operations such as material handling and sorting, pneumatic conveying, heating, cooling, aerating, dust collection, and general HVAC. Once sorted, recycling is very similar to the manufacturing of original materials. Glass and metal are crushed, melted down, and purified, then remanufactured into such items as bottles, cans, countertops, and even concrete aggregate. Paper and cardboard are treated in chemical solutions and heated to recover the organic wood fibers to produce new product.With the broadest product range in our industry, Northern Fan can supply the equipment needed for the recycle industry’s many air moving applications. Our high quality and reliable fans and blowers will do the jobs – from transporting strands of shredded paper to providing circulation in glass ovens.

Roof Exhaust Fans and Roof Ventilators

Roof Exhaust Fans & Ventilators

Proper ventilation requires that there be a movement or circulation of the air within the space and that the temperature and humidity be maintained within a range that allows adequate evaporation of perspiration from the skin. It was formerly believed that the discomfort, headache, and lethargy commonly associated with poor ventilation were caused entirely by the increase in the amount of carbon dioxide and the decrease in the oxygen content of the air. There is evidence to show, however, that the deleterious effects result largely from interference with the heat-regulating mechanism of the body. Lack of air currents and the increase in relative humidity and temperature (especially noticeable in crowded, poorly ventilated places) prevent normal evaporation of perspiration and loss of heat from the surface of the skin.

A simple roof ventilator is essentially an opening in the roof with a cover to keep out rain and to prevent winds from interfering with its functioning. Natural convection is an appreciable aid to ventilation in a large building only if it contains sources of large amounts of heat. A further useful adjunct is a fan fan, device for agitating air or gases or moving them from one location to another. Mechanical fans with revolving blades are used for ventilation, in manufacturing, in winnowing grain, to remove dust, cuttings, or other waste, or to provide draft for a fire. The addition of distribution ducts to the fan and a system for forcing air into the building provides greater efficiency. Outlets are designed to attain maximum mixing of air and to move large amounts of air at low velocity so that temperature layers are eliminated. Factories have special suction hoods and enclosures to draw away localized dust, fumes, and heat. Incoming air may be cleaned of dust by filters or electrostatic precipitators.

Roof Exhaust Fan Ventilation

Natural ventilation depends on winds outside and convection currents inside a building. Winds raise air pressure slightly on the windward side of a building and lower it slightly on the lee side. The pressure difference promotes circulation into the building on the windward side and out of it on the lee side. Convection currents are caused by the sinking of colder and therefore heavier air, which displaces the warmer air. A building may have a roof ventilator to allow the rising warm air to escape. If there is an opening to the outside at the bottom of the building, fresh, cool air will be drawn in.

Deep mines, underwater tunnels, and other subterranean and submarine environments require elaborate mechanically operated systems for maintaining the air supply in a healthful condition. The lives of those working in, or traveling through, such areas depend upon a constant supply of fresh air; not only must the systems used be highly efficient, but there should be provision for emergencies in case of failure of the apparatus in operation. An outgrowth of studies of problems of ventilation is the development of methods of air conditioning heat pump is a reversible device that does mechanical work to extract heat from a cooler place and deliver heat to a warmer place. The heat delivered to the warmer place is, approximately, the sum of the original heat and the work done.

Such systems, unlike ordinary methods of ventilation, are independent of outdoor atmospheric conditions and can, therefore, maintain the indoor atmosphere at the most healthful temperature and humidity and can free the air of dust and other undesirable materials. They accomplish this, however, at a considerable cost in energy.

Roof Exhaust Fan Ventilator Uses

Roof ventilators are another option. They work in both summer and winter. In summer, roof ventilators reduce the build up of heat in the ceiling spaces, reducing the heat load on your insulation, meaning that the insulation works more effectively. In turn, you will save on your electricity bills as the air-conditioning systems will not have to work as hard. In winter, it reduces the amount of condensation that forms when warm, moist air from exhaust fans meets cold surfaces. Roof ventilators will also reduce the amount of corrosion and timber that occurs because of condensation. Roof ventilators should be installed where there is sarking underneath tiled roofs, when metal deck roofing is used, and when there is evidence of condensation in the roof spaces or ceilings.

A reliable ventilation system that can operate during a fire is both vital and essential. It prevents smoke logging, allows people to escape quickly, minimizes damages to property and contents and enables firemen to attack the fire without hindrance. Such power roof ventilators have the added advantage of providing normal day to day ventilation and in many cases can also be fitted with duct work for use in multi storey buildings.

Radial Blowers

Radial Blowers and Radial Fans

Radial Blower fans are used for many purposes these days whether that be for items found in most households or in cars or factories. They play an integral part in our everyday lives and will do so for many years to come.

Northern Industrial Co. is a world wide distributor of industrial process ans OEM fans and blowers, as well as fan components; including high pressure blowers, high temperature fans, spark resistant and explosion proof ventilators, tubeaxial and vaneaxial high pressure ventilators. Canada Blower also does existing fans and blowers repairs, re-build, as well as dynamical wheels balancing.

Radial Blower Applications

A radial Blower fan is used in a large number of different industries, whether that be for the fan in your car or a fan in your computer to keep it from heating up too much. The word Radial Blower means spreading out of a common centre which is how most fans work. They can also be used in large industrial type settings where there is a need to push either cooling air or just making sure there is air flow through a certain area.

Radial Blower fans can also be known as a centrifugal fan, which is made up of three different types of blade settings. They are the straight steel plate paddle wheel, the forward multi-vane multi-blade and the backward turbo vane. They are also used in Industrial type situations such as factories, large underground carparks and gymnasiums. They can be used in lots of different situations where there are large enclosed open spaces which need some type of circulation, whether that be blowing cold air through the premises or to just have some sort of air movement. There are different types of fans, which can be put in an industrial factory such as a mounted fan or a freestanding fan. Obviously to do a large area you need a large fan so having it mounted can be a benefit whilst having it freestanding can also be a benefit because it can be moved if need be. There are also different noise levels of these fans but most fans these days are relatively quiet especially in an area such as a factory.

A radial Blower fan is used in so many different ways and usually run by using electricity although a radial Blower fan can also run off a generator. Most households have a radial Blower fan, there is generally some sort of fan found in most houses. A radial Blower fan can be just your normal portable fan or a ceiling fan is normal is most humid areas. When you do have a ceiling fan it’s important to note that most of them must be put in by an experienced electrician otherwise you could have some serious problems with them. They are certainly a lot more economical than running an air conditioner, which is why they are so popular in humid areas where having some air flow cools down the place. Radial Blower fans are also found in most air conditioning units now, they are used to blow cooled air out of the unit and into the room.

Automobiles also have radial Blower fans placed in them to keep them from overheating, this is probably the most popular use for radial fans in this day and age. They’re placed under the hood of the car to keep the motor cool and stop it from overheating. Another use for radial Blower fans is also the home computer, obviously these are a lot smaller than most radial Blower fans but they get the job done, by stopping the computer from overheating also.

Axial Ventilator Fans and Other Air Ventilators

Axial Ventilators

Axial flow fans or industrial axial fans move an air stream along the axis of the fan. The way these fans work is similar to the propeller on an airplane: the fan blades generate an aerodynamic lift that pressurizes the air. Axial Northern Fans use a propeller to draw the air into the fan then discharge it in the same axial direction. Typical types of industrial axial fans include:

* Tube axial fans (also called duct fans),
* Panel fans (also called wall fans),
* Personnel coolers,
* Roof Ventilators,
* Air circulators,
* Vaneaxial fans

As specialists in air moving applications and equipment, Buffalo Fan Co. understands industrial blower technology and designs systems for a host of facilities and industries, and work with the best names in industrial blower equipment, including TCF, NYB, IAP. A blower can achieve much higher pressure than a fan, and can be used to produce negative pressures for industrial vacuum systems. In selecting the right industrial blower equipment to serve your needs, you must consider conditions such as:

– Required airflow through the blower;
– Static pressure through the complete system;
– Suction pressure at the blower inlet;
– Airflow conditions through the blower;
– Altitude at which the blower will be operating;
– Composition of what is going through the blower – for example, is it explosive or flammable ?

Industrial Fans and Blower Fans

Northern Fan and exhaust TCF fans do not differ significantly from non-industrial types in their basic operation. The main characteristics that make blowers and fans industrial are the heavy duty construction, wheel type, shaft and bearings, materials and gauges used. Northern Fan Co. will work through all of the necessary considerations in developing an industrial air movement system that best addresses your needs and provides you with the most advanced industrial blowers and industrial TCF exhaust fans from the leading manufacturers.

Propeller / axial wheel types may include:

– Fixed pitch
– Adjustable pitch

Bifurcated Fans are direct driven axial fans where the motor is encased in a metal box to isolate it from the airflow. The term “bifurcated” means split in two branches, or parts. In terms of a bifurcated fan, the fan is constructed so that the fan rests between two forked channels, which carry the air, creating a void behind the axis of the fan itself. This makes Northern bifurcated fans ideal for exhausting or re-circulating fumes, gases and hot air up to high temperatures. The bifurcated fan motor must have access to ambient air, and have non-overloading characteristics. TCF bifurcated fans are typically used when the motor needs to be shielded from hot gases or other threatening conditions.

HVLS fans blanket a very large area with constantly moving air to create an expansive comfort zone. As a result, the big ceiling fan (up to 24 feet in diameter) can create an evaporative cooling effect during the summer months while de-stratifying uneven floor to ceiling temperatures in the winter. This results in significant energy savings since the heating system cycles less frequently.

Industrial Fans and Blowers

Industrial fans and blowers are mainly used to circulate the movement of air and gas in ventilation applications. Their main function is to replace impure or contaminated air with fresh air by swirling it around. Almost every industry, including agricultural, chemical, medical, oil and gas, automotive, food processing, mining and construction use blowers for different purposes such as drying, reducing heat levels, reducing smoke and odors, processing and controlling gaseous fumes.

Industrial Fans & Blowers Manufacturers and Suppliers

Industrial blowers are manufactured using a range of durable plastics and metals, or a combination of both materials. For example, industrial blowers operating in corrosive environments are usually made of polypropylene because it provides greater structural integrity and corrosion resistance, and will never de-laminate. Typical recommendations in the construction of industrial blowers are – fiberglass for temperatures above 220 degrees, and metal if pressure is above 10 w.g. (water gage).

The size of the blower may be regulated by the size of the environment in which it is to be operated. For instance, some units are big enough to house both the fan and its power supply. Smaller, portable blowers are mainly used for cleanups and in spaces that require temporary circulation or air transfer.

The air movement and control association recognizes three classes of industrial blowers, classified with numerical designation that is based on how the fan is constructed. The United States’ specifications for industrial blowers depend on the airflow in CFM (cubic feet per minute), static pressure in inches, water gage, altitude and approximate air temperature. Here’s an example:

Air conditioning can often become too large of an expense for industrial areas, but the good news is that an industrial fan can bring some much needed relief in this case. Industrial electric fans can be quite helpful for places where heat stratification, dampness, and stagnant air become frequent problems. Also, for high static pressure an industrial fan is what you need. Also known as an industrial electric blower, these units replace air as well by blowing out the old and stagnant air for a wide area that otherwise would collect this air without replenishing it in entirety.

Large Industrial Fans

Industrial fans also are helpful in removing pollutants like dust and metal particles, carbon monoxide, nitrous oxides, sulfur dioxide, sulfuric acid, and hydrocarbon solvents. Plus, industrial electric fans clearly do not use as much electricity as an air conditioner, circulating air and cooling it at a fast rate for a large space. With high-powered, energy-efficient motors, the larger motor of an industrial fan is actually guaranteed to save energy costs.
