Rosenberg HVAC OEM Axial Fans With Winglets -Image

Rosenberg USA has expanded its OEM AC axial fan range to include winglet-bladed models up to 40 inches in diameter. Rosenberg AC axial fans with winglet tips are now available in five sizes from 22 inches to 40 inches. The expanded AC line is ideal for many HVAC applications, including condensers, heaters, evaporators, heat pumps and air-cooled water chillers.

The Rosenberg AC axial line now includes 22-inch (560 mm), 25-inch (630 mm), 28-inch (710 mm), 31.5-inch (800 mm) and 40-inch (1000 mm) models. They are available in 208, 230 or 460 volt operation at 60 Hz. All five sizes employ six (6) finned blades.

Rosenberg's finned or winglet-style blade design reduces noise by up to three (3) dBs and boosts fan performance by decreasing turbulence at the wing tips. This improves fluid dynamics and increases fan output, providing a steep airflow/pressure curve. Rosenberg's 40-inch axial fans are capable of delivering nearly 16,000 cfm at free air.

Rosenberg AC axial fans can be installed in any position and speed is 100% infinitely variable. Thermal contacts provide standard motor protection. Insulation is to Class F and side cable connection or connecting box on the rear side of the motor are standard.

The fans can also be specified with electronic commutation. Electronically commutated (EC) fans feature standard AC input power, and extended-life, low-temperature brushless DC motors that are controlled by maintenance-free electronic circuitry. With integrated electronic speed control, Rosenberg fan motors run cooler and quieter.

In addition to a wide selection of standard products, Rosenberg's engineering and manufacturing specialists also offer application assistance and work directly with customers to provide customized solutions to their air movement problems. They are skilled at producing fans that match customers' unique needs such as special finishes, voltages or frequencies.
