Performance range of compact fan line Compact and universally applicable: Direct driven or with belt drive for flow rates up to The compact industrial centrifugal fan made by Pollrich DLK Fan Factories is providing the solution for conveying small and medium size fl ow rates at low and moderate pressure levels. The compact industrial centrifugal fan, either direct or belt driven, is characterised by its light and space saving design providing a solution for almost any installation situation. The modular confi guration which runs like a golden thread throughout all series and sizes allows an...

High pressure impellers: Due to a small diameter ratio and a reduced width of the high pressure impeller, combined with the matching casing, we achieve Medium pressure impellers: For the medium pressure range the impeller diameter ratios 40 to 53 are used. With these impellers, we reach even at flow rates of 70,000 m³/h a pressure increase of 8,000 Pa. total pressure increases up to 10,000 Pa for flow rates up to 15,000 m³/h.

Low pressure impellers: For conveying of large flow rates at low pressures, impellers with a larger diameter ratio are being used. This impeller type in combination with an optimal casing allows efficiencies of far more than 80% due to the outstanding aerodynamical performance. Blade profiles Backward inclined straight blades Backward inclined aerofoil blades Backward inclined curved blades Three different blade profiles are available in order to ensure an optimal match of the operating point and the operating conditions. Volume flow rates between 480 m³/h to 150.000 m³/h can be conveyed by...

We are continuously testing and improving the complete range of impeller geometries in the most diverse assembly situations and for the most diverse requirements in our companies aerodynamical laboratory. Besides the general optimisation of the efficiency and fluid dynamical features of our fans by using modern CFD simulation software and FEM calculation methods, the emphasis is thereby on the reduction of aerodynamically induced sound sources on the impellers by - among other aspects - avoidance of distinct frequency peaks. Additional optimisation in terms of material and material...

A fan product line evolving from two opposing production philosophies: The compact fan product line from Pollrich DLK Fan Factories is the synthesis of more than 100 years experience in the development of customised industrial solutions and the manufacturing know-how for the standardised series demand from OEM applications. “A modular configuration system” of single inlet centrifugal fans for all requirements. Every industry has its specifi c requirements which are passed on to their system suppliers. Especially in the fan manufacturing, this means to design customer specifi c solutions...
