Effective Air Cooling with Industrial Fans
Need effective cooling and air movement in your process? Our Product Roundup shows some of the options available.
Fan Provides High Pressure Capability at Low Speeds
Multi-Wing’s M-Series axial fans have high pressure capability at low speeds resulting in low noise levels in most compact heat exchangers. Features include one-piece injection-molded fan of engineered thermoplastic materials, a broad paddle-shaped profile and three standard pitch angles of 30°, 35° and 40°. The fan has fan fixed-pitch, positively set fan blades. Other features include one-piece aluminum-alloy boss, which is available in a range of bore/fixing configurations. It is also available in a version accommodating a range of thermoplastic taper-lock bushings. It is only available in a configuration where the fan blades rotate in a clockwise direction when facing the airstream.

Flexible Fan Packs
A range of customizable axial fan packs, SmartPack is engineered to meet low noise and efficiency requirements in industrial refrigeration and heat exchange applications. The custom fan packages include a metal frame with a plastic skin; custom-configured Multi-Wing fan; an AC or EC motor; and protective fan guard. The packages are offered in ~22.05, 24.80, 27.95, 31.50 and 35.43” width (560, 630, 710, 800 and 900 mm) diameters. The AC fan package meets strict industrial requirements and is available worldwide. The EC version achieves and maintains the highest possible efficiency levels within a wide operating range, including temperatures of -40 to 176°F (-40 to 80°C).

High Volume, Low Speed Fan for Industrial Cooling
Titan industrial fan is supplied in five sizes ranging from 14 to 24’ blade spans. The direct-drive electronically commuted motor allows for an efficient, lightweight product, says the company. Other features include “lubricated for life” bearings and a touchscreen interface that allows users to integrate the unit with a building-management system through industry-standard protocols.
Blade Extensions for Axial Fans and Fan Drives
BLEX blade extensions are made from a durable nylon textile. The flexible fabric is designed to adapt the fan diameter to the contour of the shroud, thereby reducing the clearance to ZeroTip. The flexible material produces a 2 to 3 dB(A) noise reduction. The same airflow rate can be achieved while reducing pitch angle and fan speed, thus lowering power consumption.
Ultra-Low-Sound Axial Industrial Fans
Swifter ULS Series provide solutions for sound-sensitive environments. The axial fans are available in seven standard diameters ranging from 63 to 156”. The extra-wide chord-width curved blades allow for smooth airflow with minimum air separation and turbulence. Constructed of high strength, lightweight fiberglass-reinforced polyester with a UV-resistant surface coating and leading-edge protection, the single-piece molded fans offer performance, reliability and durability. They are suited for use as OEM or replacement parts in equipment such as evaporators, cooling towers, condensers and exhaust and ventilation systems.

Corrosion-Resistant Fans for Off-shore Applications
Designed to be used for human habitability and machinery subcomponent systems such as cooling exhaust, and combustion as well as process functions, corrosion-resistant fans have IEEE45-rated motors and suitable marine electrical connections. Intended for use on oil platforms and other marine installations, the JM tubeaxial fans and JMG vaneaxial fans include an adjustable-pitch feature that gives users the flexibility to make any necessary changes to flow or pressure.
Direct-Drive Panel Fan Offers Quiet Operation
Model APK is are available in diameters from 12 through 36” with capacities ranging to 23,000 cfm. The direct-drive panel fan has an airfoil adjustable-pitch impeller for precise performance matching. A deep-drawn venturi allows for exceptional pressure development. Fan blades are available in either pressure cast aluminum or glass-reinforced polypropylene (GRP).
Semicool Precision Fans, Custom Cooling Systems for Semiconductors
A line of vaneaxial fans originally designed for critical military and aerospace applications, the SemiCool systems offer precise temperature control in a compact package. Complete systems include high reliability fans, optimized heat exchangers and custom ductwork. Alternatively, customers can integrate the vaneaxial fans into their own cooling subsystems. Optimized fans with diameters ranging from 6 to 8” provide airflows of 900 cfm at 10 iwg. Designed to operate with 400 Hz industrial power converters, the fans offer rapid response, infinite speed control and minimal space requirements. These features are designed to support consistent systems operating temperatures.
Constant-Pressure, Constant-Airflow Blowers
Constant pressure and constant airflow blowers automatically adjust to maintain optimum performance levels in changing conditions. The 180x180L EC double-inlet models are CE-approved and meet ErP 2015 efficiency requirements. The forward-curved centrifugal blowers, designated the GDSV8 Series, are powered by 230 V single-phase, 50/60 Hz EC motors. They run at speeds as high as 2255 rpm and generate a maximum airflow of more than 1000 cfm at free air. Speed control is possible through pulse-width modulation, 0 to 10 VDC, or a potentiometer.
