Industrial Fans

Air kits are provided with a forward curved design in a double-width, double-inlet arrangement. This design allows for a low operating speed and economically sized shafting. These air kits provide reliable and quiet operation in ovens and plenums where it is not desirable to have the fan bearings in the airstream. The air kit design is commonly used to economically provide large volumes of air (up to 100,000 CFM) at static pressures up to 6″ w.g. in a compact design.

Air kits may be supplied in two standard configurations:

1. The single fan kit has one fan impeller centered in the plenum.

2. The twin fan has two impellers spaced on a common shaft in such a way that the restriction is the same on all four inlets.

Tubeaxial fans are designed to handle a wide range of requirements, from general ventilation to process air supply. The mounting flexibility makes it an ideal choice for many industrial and commercial applications. Units are available as direct or belt driven, with steel or aluminum impellers that are fixed or adjustable blade pitch.

Vaneaxial fans are designed for applications where large volumes of air are required at moderate to high pressures. Direct and belt driven models, with fixed and adjustable blade impellers, are available. The tubular design and high impeller efficiency provides maximum performance while using minimal space.

Centrifugal fans are designed for general HVAC and industrial applications where large volumes of clean air are required at low to moderate pressures. With backward inclined, backward curved, backward inclined airfoil and forward curved impeller types, centrifugal fans offer the flexibility to match the performance and application at the highest efficiency. Most models are available in single-wide or double-wide configurations, which allow for even higher volumes of air.

Filtered supply fans are belt driven centrifugal fans that are designed to provide filtered outside air to buildings such as manufacturing plants, warehouses and auditoriums. Fresh make-up air is supplied to replace the air lost through industrial processes, fume hood exhaust or general building ventilation.

Centrifugal roof and wall exhausters are available in direct and belt driven models, featuring backward inclined, non-overloading centrifugal impellers for maximum efficiency and quiet operation. A variety of configurations are available for the exhaust of relatively clean air and grease-laden air.

Fiberglass fans are specifically designed for the exhaust of moisture-laden, corrosive or chemically contaminated air. All fans feature molded fiberglass housings that are virtually impossible to dent, crack or break. FRP offers a more economical solution compared to stainless steel or other exotic alloys. Multiple impeller types and materials are available to meet any corrosive process requirements while maintaining quiet operation and high efficiency.

Gravity, or natural, ventilation is a means of ventilating a building by strategically placing openings in the building exterior in order to take advantage of naturally occurring phenomena. With a wide range of designs and styles, Air Cleaning Technology can supply the right gravity ventilator whether it is selected based on performance, size, aesthetic appeal, weather resistance, construction, climate or cost. Gravity ventilators are designed to provide relief (exhaust) and intake (supply) airflow for a number of commercial and light industrial applications.

Inline centrifugal fans are designed for general HVAC and industrial applications where large volumes of clean air are required at low to moderate pressures. Inline centrifugal fans provide the performance of a centrifugal fan with the space saving advantages of an axial type fan. With a variety of designs to choose from, these fans offer the flexibility to meet the performance and application requirements at very high efficiencies.

Laboratories and research facilities exhaust a wide variety of harmful fumes. In concentrated forms, these fumes can be hazardous to human life. Contaminated air must be exhausted in a way that prevents it from returning into the building and surrounding locations where people may be present. To effectively exhaust these fumes, which in many cases are corrosive and/or explosive in nature, fans are connected to one or more fume hoods to draw the contaminated air through. For proper ventilation, exhaust fans must be capable of moving air at high velocities to achieve a high plume height, as well as entraining clean ambient air to dilute the chemical concentration in the airstream. Twin City Fan & Blower offers a complete line of laboratory and fume exhaust fans for meeting the most stringent industry standards. Our laboratory exhaust fans are often constructed of specialty materials to withstand the fumes associated with these environments.

Mancoolers are constructed of high-quality axial fans and are designed for general industrial use. The mounted units are constructed on a movable base – both the inlet and the outlet are provided with screens as standard, and are fabricated to meet OSHA safety requirements. The fan’s swivel base allows for a full 360° rotation, providing airflow from any angle. The stationary units can be adjusted for airflow in any direction and are manufactured with a predrilled base plate for wall, column, ceiling or floor mounting.

Mixed flow fans are designed for general HVAC and industrial applications where large volumes of clean air are required at low to moderate pressures. Mixed flow fans provide the performance of a centrifugal fan with the space saving advantages of an axial-type fan. With a variety of designs to choose from, these fans offer the flexibility to meet the performance and application requirements at very high efficiencies.

Plenum fans are designed for general HVAC applications where large volumes of clean air are required at low to moderate pressures. Backward inclined airfoil impellers provide high efficiency, performance and sound characteristics needed for the most stringent HVAC applications. With housed or open designs, as well as direct or belt driven options, plenum fans provide the flexibility to match the performance and application at the highest efficiency.

Plug fans offer great versatility for complex system configurations. Equipped with a gusseted mounting panel, they are mounted directly to the plenum wall separating the motor and drive components from the process air. Plug fans provide high efficiency recirculation air with the benefit of easy installation and removal.

Pressure blowers are ideal for applications requiring high pressures at relatively low volumes of air. Pressure blower performance will remain stable through the operating range and can be turned down to zero flow via a discharge damper. Air Cleaning Technology offers a wide range of blower types, including turbo and heavy-duty pressure blowers, and sizes to meet clean or particulate-laden airstream applications. A variety of impeller types are available as well, such as radial back plate, backward curved, open radial and shrouded. Housings are fabricated of steel, cast aluminum or cast iron. Pressure blowers are used in many industrial applications including dust collection, flue gas recirculation, material handling, explosion-proof processes and wet well station exhaust.

Radial bladed fans provide a solution for a wide range of industrial applications. The heavy-gauge, all-welded construction has earned it the reputation of being the “workhorse” of the industry — a design proven by years of service handling dirty, abrasive, sticky or bulky particulate-laden airstreams. With multiple sizes and materials available there is a fan available to meet the applications needs.

Radial tip and high efficiency fans offer great efficiencies for a wide range of applications requiring high airflow and moderate pressures. The non-overloading design can handle high temperatures, corrosive airstreams and light particulate where the radial tip designs are better suited for dirty, particulate-laden air. With high airflows the radial tip fan is much more efficient than the comparable radial blade fan.

Roof ventilators provide cost-effective, general purpose exhaust ventilation of commercial buildings as well as a large variety of industrial applications. Direct and belt driven models are available with cast aluminum, adjustable pitch or fabricated steel, fixed pitch impellers to meet specific application requirements.

Emergency smoke exhaust systems are designed to remove smoke and heat from buildings in the event of a fire. These systems play a crucial role in increasing occupant safety and allowing rescue personnel to safely enter burning buildings. Air Cleaning Technology offers a full line of smoke and heat fans capable of withstanding a minimum temperature of 500°F for four hours or 1,000°F for 15 minutes. Our inline smoke and heat fans are also available in a vertical roof mount or horizontal discharge configuration featuring a stack cap with butterfly dampers and a fusible link designed to stay open in the event of a fire.

Utility Sets are an excellent choice for general exhaust and supply requirements of commercial and light industrial applications. They are suitable for indoor usage and outdoor usage, with the addition of a weather cover to enclose the motor and drives. Fan housings are available in lock-seam galvanized steel, welded heavy-gauge steel, aluminum or stainless steel.

Wall Mounted Fans are designed for cost-effective, general ventilation. They are available in direct and belt driven models, with aluminum or steel impellers. Fixed or adjustable pitch models are offered to meet a variety of application requirements.
