Save time when lookng for industrial process and equipment cooling fans by using our product roundup showcasing products from a range of manufacturers.

Sickle-Blade Fan

Sickle Series blades are built for nearly any air-moving application. The sickle blade’s large chord length and thin trailing edge combine to generate greater pressure at slower speeds while significantly reducing noise levels. Company also offers fan impeller solutions for applications that have reduced noise by up to 7 dBA. Available in fiberglass-reinforced nylon, fiberglass-reinforced polypropylene, and aluminum, the fans are offered in diameters from 11 to 77".

Plug Fans

The compact “cartridge” design of plug fans makes them suitable for applications where the system plenum acts as the fan housing, such as those in freezers, ovens, dryers and other high-capacity systems. Specifications include capacities to 74,000 cfm; pressures to 20" wg; and temperatures to 1,300°F (704°C). Offered in 12 sizes ranging from 12 to 49", the fans can be specified with a choice of two backwardly inclined wheels: AcoustaFoil (with airfoil blades) or PLR (with flat, single-thickness blades).Wheels are dynamically balanced, and all fans are checked at specified operating speed.

Twisted, Tapered Aluminum Airfoil Fan

The design of PowerFlo incorporates naturally occurring physics by countering centrifugal forces to blade air load reactions. Features include a twisted and tapered blade design that allows lower RPMs for reduced noise and quiet operation as well as uniform velocity across the blade length. A small hub reduces or eliminates dead spots. It is offered in diameters from 4 to 14'.

Industrial Hanging Fine-Mist Fogging Fan

Aquafog Turbo XE atomizing fans can be used for evaporative cooling or indoor and outdoor humidification applications. The nozzle-free fans can atomize ordinary water supplies into a fine, mist-like fog. Utilizing high-speed centrifugal force and powerful airflow, the unit can propel a misty-fog stream up to 35' away and can humidify up to 40,000 ft³. An optional dwell-free oscillator can be added for applications that require sweeping action to increase coverage and enhance circulation.

Airfoil Plug Fan

Direct-drive airfoil plug fan offers a compact alternative to belt-drive plug fans. Applications include packaged equipment for cooling, drying, dust collection and recirculation systems. When coupled with a variable frequency drive, performance is not limited to synchronous motor speeds. Product line includes plug fan sizes from 12.25 to 30" and static pressures to 12". Direct drive temperature maximum typically is limited to 180°F (82°C), but it can be higher when the fan is equipped with factory cooling wheel and insulated plug panels.

Motorized Impeller

Model XR combines the efficiency of a backward-curved airfoil impeller with an external rotor motor. Suitable for supply or exhaust applications, the motorized impeller is fully speed controllable. Both motor and impeller are located directly in the airstream, where the impeller acts as a rotating heat sink to ensure heat dissipation and efficient motor cooling.

Axial Fans

Line includes axial fans in seven sizes, sixteen models and three mounting types. Standard features include spark-resistant cast aluminum propellers and totally enclosed (TEFC or TENV) motors. Explosionproof motors are also available. With capacities up to 28,490 cfm, the fans can be used for spot cooling of heat-generating equipment where large volumes of air are required; temporary spot cooling; and cooling personnel.

Direct-Drive Panel Fan

Model DPF offers belt-driven performance without the use of belts and pulleys. The key is an adjustable-pitch impeller that can be set to meet exact performance requirements. The direct-drive panel fan ships standard with a deep drawn venturi. Fan housings are available in several materials, including painted steel, aluminum and stainless steel. Impeller blade pitch adjustment can be carried out while still attached to the fan’s drive shaft. Impeller blades are available in cast aluminum or nylon-glass fiber construction. Panels can be custom formed for non-standard applications. Performance ranges from 300 to 100,000 cfm.

Airfoil Wheel

Type FA wheel is offered in diameters from 12 to 60" in both clockwise and counter-clockwise rotations. With an airfoil design, the wheel is manufactured as a single piece in solid fiberglass and coated with a corrosion-resistant vinylester resin. Features include tapered inlet side and airfoil blades, and it has non-overloading horsepower characteristic curve. When used in conjunction with a precision inlet cone, it efficiently moves large volumes of air at high pressures with low noise characteristics at low RPM.

Square Fans

Square fans combine heavy-gauge, industrial construction with a direct-drive design for tight footprints. Fans are designed for clean-air applications such as product cooling, product drying, pneumatic conveying, supply air, and exhaust on the clean-air side of dust collection systems. The line is offered in 11 sizes with fan static pressures to 22" w.c. and capacities to 29,000 cfm.
