Centrifugal Backward Inclined Fans For General Purposes

Wheel Diameters from 5″ to 100″
Air Volumes up to 500,000 CFM
Static Pressures up to 50″ W.G.
Horsepower Requirements up to 1,000 HP
Temperatures to 1000° F
Maximum Efficiency to 83%

Classes: I through V

Arrangement: Belt Drive and Direct Drive fans

Design Features: Clean air handling fan designs, most commonly associated with the non overloading horsepower characteristic. Typically, large volumes of air at low to moderate pressures at high efficiencies are these fans trademark. Additionally, the horsepower curve has a peak value for any given speed, thereby allowing fan motor selection to prevent an over load condition given gas density remains constant. All fan models available in SWSI or DWDI and in standard AMCA fan / blower arrangements.

Choice of backward-inclined, airfoil, backward-curved or forward-curved fan wheel, all types of motors, drive gaurds, air dampers and shutters, high temperature, spark-resistant / explosion proof fan construction.

Service and Applications: General ventilating, light industrial, commercial air moving fan systems. Combustion air on kilns and furnaces, baghouse forced draft, blower aeration, industrial air conditioning.

Industrial Backward Curved Fans

Wheel Diameters from 24″ to 110″
Air Volumes up to 600,000 CFM
Static Pressures up to 45″ W.G.
Horsepower Requirements up to 1,000 HP
Temperatures to 1000° F
Maximum Efficiency to 82%

Arrangement: Belt Drive and Direct Drive fans

Design Features: These high-efficient backward curved, airfoil and backwardly inclined fans employ high efficiency impeller design for use in clean or moderately dust laden air streams. Designed as a higher efficiency alternative to a radial tip fan.

Typical performances ranges are the same as a radial tip fan with increased efficiency and non-overloading horsepower characteristics. The rugged standard design allows these fans to be used in many of the same applications as the radial tip blowers. Backwardly curved fans are available in all standard AMCA arrangements and with most standard fan options.

Fans have helped to create safer and more pleasant internal environments for hundreds of years. The invention of mechanical fans is found in the industrial revolution and the first commercially viable electric fans were made available to the US public early in the 1930's.

Today the technology behind fan manufacturing and ventilation solutions have sky-rocketed to create fans for virtually every use from cooling devices in a server room; to ventilation in a manufacturing plant; to keeping a bathroom clear of damp air.

Generally speaking, fans and their accessories can be divided into 3 main usage categories: domestic use, industrial use and commercial use.

Industrial Fans will often have a very robust requirement and it is essential to involve experienced engineers with the installation of such ventilation. Other than just determining whether the fans will be required for air supply or for exhaust functions (i.e.: as an extractor fan) the engineer or installation technician will need to be keenly aware of both the working temperatures of the units as well as any thermal protection qualities of its associated housing or frame.

Some industrial fans will come with controllable speeds which can be very handy in a changeable internal environment, especially with regards to saving on ventilation costs at times when the air regulation needs of an area are reduced. Special features such as built in monitoring and systems integration come in handy when working in a potentially hazardous environment for example when chemicals or volatile substances are involved. Generally speaking, fire resistance and corrosion resistance are both 'plus' features for any industrial ventilation setup. Above the 'plus' one will need to consider the health and safety requirements of your region such as vibration or noise control and air quality regulations related to worker health.

Commercial Fans and Ventilators would not have as robust a requirement but the overall integration of fans into the building structure and management system is key to efficiency. Automatic ventilation in refrigeration units or in rooms that will typically contain many people at the same time will keep areas safe and comfortable. Operational areas such as server rooms (also known as data rooms) and elevators will need to provide adequate ventilation, usually in the form of extractor fans, to remove excess heat generated by the operating machinery which often runs continuously. Commercial ventilation also acts as a barrier to unwanted external influences such as insects, pollution and natural allergens.

Lastly domestic fans find their main purpose in providing less costly air quality solutions. There are two ways to cut costs with a domestic ventilation solution. You can invest in a 'cheap and cheerful' unit from the beginning resulting in a smaller initial cost or you can install a slightly more costly fan and ducting system with operational features that help you save on heating and ventilation costs in the long run. There are a wide variety of low energy extractor fans and ventilation units are now available for kitchens, washrooms and living rooms. In addition heat recovery units now help you to use the heat from stale air that is being extracted to warm-up fresh air that is being pulled in by your system.
