International. Rosenberg announced the launch of its new 560mm Gen 3+ EC rear-curved fan module that features higher efficiency, less noise and more airflow for data center air handling and cooling units, as well as transformer, compressor and wind power cooling applications.
The Rosenberg GKHM 560-CII.183.6NA IE Gen3+ (PN#N88-56700) is a compact, optimized fan unit that delivers up to 70% efficiency. The EC Gen 3+ motor operates at consistently high efficiency, even at part-load ranges, and is paired with an advanced aluminum impeller featuring five rear-curved profiled blades and an efficiency-optimized circumferential diffuser.
The N88-56700 is remarkably quiet for a fan of its size, with operating noise levels ranging from a maximum of just 89 dB to a minimum of 68 db.
The new fans also deliver up to 12% more air than previous models, depending on the operating point. The N88-56700 operates in input voltage ranges of 3~200-240 and 3~380-480, simplifying specifications. In the range of 3~200-240 VAC, the operating airflow is 8000 cfm at 3" pressure. At 3~380-480 VAC, the N88-56700 generates 8000 CFM at 4" pressure. Outdoors, the maximum airflow is nearly 13,000 CFM in any voltage range.
Like all Rosenberg EC plug-in fans, the N88-56700 features a low installation depth, easy integration and maintenance-free operation thanks to lifetime lubricated ball bearings. The fan speed is infinitely adjustable.
