Product Roundup: April 2013
Cooling Tower Fan
Swifter CTX Series is suited for cooling towers, air-cooled heat exchangers and evaporators. Fan sizes in the industrial axial fiberglass fan line range from 5 to 40' diameter in four- to 16-bladed configurations. Custom fan sizes, colors and configurations are also available. The cooling tower fans incorporate high efficiency, patented airfoils and proprietary technology, in which the fan blades are molded into a single-piece contiguous composite blade consisting of an outer fiberglass shell with an inner high density polyurethane foam core.
FRP Axial Flow Fans
Tuf-Lite III has a one-piece fiberglass-reinforced polyester construction to help ensure good leading and trailing edge protection as well as UV protection. The individually balanced, interchangeable blades can be installed in current designs of the company’s hubs. Standard sizes are available from 5 to 40' in diameter for heat exchanger and cooling tower applications.
Hudson Products Corp.
Series P2H and P3H utilize blades with an airfoil design. The blade dimension is chosen to provide a uniform air speed over the entire usable blade area. Impeller diameters range from 5.5 to 19.25" with 25° to 50° pitch to suit specific application requirements. The blades are fixed in the hub, ensuring a preset blade angle that cannot move or change under load. The blades are made from high strength, injection-molded thermoplastics or die-cast aluminum.
Cast Aluminum Blowers
Blowers are offered in 4, 6 or 8" diameter with capacities to 1,550 cfm. Features include a cast aluminum housing, heavy-duty steel base, and forward-curved blowers. It offers clockwise rotation and can be rotated to four positions. Suitable for application temperatures of 0 to 160°F (-17 to 71°C), the blowers have circular inlet and outlet collars and single- or three-phase TEFC motors.
Continental Fan Manufacturing Inc.
Fans in 5 Impeller Blade Profiles
The company’s impellers are offered in five impeller blade profiles engineered to meet the flow parameters required. Its Sickle Series blades are built for applications where low noise capabilities are needed such as refrigeration, oil coolers, compressors and generators. Available in fiberglass-reinforced nylon, fiberglass-reinforced polypropylene and aluminum, the fans are offered in diameters from 11 to 77".
Fans for Air-Cooled Heat Exchangers, Cooling Towers
Class 10000 Heavy Duty (HD) fans are designed for large fan diameter installations. Offered in clockwise (RH) and counterclockwise (LH) rotation in fan diameters from 3 to 24" (1.22 to 7.32 m), they can be configured with manually adjustable pitch. Features include a hub tube diameter of 3" for added strength and durability, resilient blade mounts and increased chord width. The blade angle can be adjusted without removing the fan blades.
Cooling Tower Fan
Ultra Quiet fan is designed for cooling tower applications where very low sound is a necessity. The wide chord blade design is well suited for low sound operation, delivering good airflow and pressure capability at reduced speed. Constructed from aluminum, the fan meets FM approval standards. It is designed for continuous duty in all cooling tower operating conditions. It utilizes marine-grade quality 5052 aluminum alloy blades.
SPX Cooling Technologies
Aluminum Manually Adjustable Fan
Series 5C15 is available in diameters from 3 to 6'. The blade is a 5" wide twisted casting available in either right or left hand twist. The aluminum plate hub comes with a properly sized mounting bushing. With a cast aluminum blade and extruded alloy center, the fan includes zinc-plated Grade 5 carbon steel bushing and clamp bolts, and ductile iron hub bushing.
Airflo Cooling Technologies
Cooling Tower Fans
Supply and exhaust fans aid the thermodynamic forces in heating or cooling fluids for process systems. Dry- or wet-surface heat exchangers, shell-and-tube exchangers and evaporative cooling systems use the company’s axial, centrifugal or pressure blower designs. Fans are available with corrosion-resistant or alloy construction for severe-duty environments. Low noise, high-efficiency fans are offered for critical installations.

Pressure Air Fans
To meet specific applications, PA fans can be built with stainless steel or alloy construction. Split housings facilitate wheel removal without disturbing connecting ductwork. Integral inlet boxes, prespin inlet dampers and opposed-blade outlet dampers all control airflow. Belt guards and shaft coolers also are common options, in addition to the various housing and wheel liners. Chicago Blower engineers are eager to design and build the pressure fan that meets your exact requirements.
Chicago Blower Corp.
Utility fans can be used in process cooling, comfort cooling and plant ventilation. They are available in sizes from 20 to 36" with 4,168 to 14,170 cfm airflows. Compact and versatile while designed for heavy industrial use, all models have heavy-duty, solid cast-aluminum propellers and OSHA-approved guards.
