Fan and motor specialist ebm-papst has developed AxiBlade, a new generation of axial fans that are state of the art and exploit every last bit of optimisation potential.
The AxiBlade concept is based on a modular system. Fan housings of varying heights with an aerodynamically optimised inlet ring are complemented by profiled impeller geometry and winglets for maximum efficiency.
The impellers have been designed for various motor combinations, which increases efficiency and reduces running noise.
Exhaust turbulence and the resulting dynamic losses can be minimized with guide vanes. The guard grilles are matched to the various combinations and aerodynamically optimized.
Not only do they protect against accidental contact, they also contribute to the high overall efficiency of the axial fans.
Thanks to their modular concept, AxiBlade axial fans can operate in a wide variety of applications with an optimum efficiency of up to 54 per cent. Noise reduction of up to 8 dB(A), can be achieved when compared with the standard axial fan.
Pressure range
The new axial fans can be ideally matched to the required application. For example, the standard fan housing with a height of 190 mm and no guide vanes is suited to low to medium pressure ranges up to 200 Pa.
Even without the guide vanes, the efficiency and operating noise of the AxiBlade are much better than the current industry standard.
Applications which require a high back pressure up to 290 Pa are able to be accomplished by the approx. 300-millimeter-high fan housing (depending on the size category) with integrated diffuser. Here, the guide vanes are essential for achieving such high energy efficiency and low noise production.
Suitable components can be combined depending on the pressure ranges required and the fans can be produced accordingly.
Since the new axial fans' footprint corresponds to the current industry standard, virtually no design changes to the end unit are necessary.
Besides the especially energy-efficient GreenTech EC motors, the new AxiBlade models are also available with the AC motors that are still widely used. Sizes 800 and 910 are currently available; an expansion of the series to include sizes 630 and 710 is planned for later this year.
