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.

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.

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.
Vaneaxial adjustable pitch designs have the additional feature of permitting the fan to be precisely matched to system requirements, saving power and reducing noise.
Compact Pressure Blowers are designed for low-capacity, low-pressure industrial processes such as glove boxes, combustion air, dust collection, fume control,. carbon systems, quench cooling, oven exhaust and conveying. The open radial wheel design makes it ideally suited for both clean air and material handing applications.
• Pressures to 23" WG, flows to 4,000 CFM.

• Compact pressure blower fans offer stable pulsation free performance from wide-open to closed-off.
• Standard radial wheel for optimum efficiency. Either welded steel, aluminum or stainless steel wheel construction is available in straight radial wheel design. Open front-plate configuration makes this wheel ideally suited for both clean air and material handling applications. Advanced wheel and aerodynamic housing design with round outlet combine for air-handling   efficiency superior to conventional radial-wheel designs.
