The new D-Series

Endurance and efficiency – these are not only the unique features of our punker fan wheels but this is characteristic for the whole punker team. Our key objective is to continuously optimize each product, no matter how good it is. Based on the former R63D wheels, we developed a new, highly efficient fan wheel series with integrated diffuser technology – in short: The “D-Series“.

The unique characteristics of this series, specifically designed for unhoused fan wheels, is more than ‘state of the art’. The mechanical efficiency static of up to 75% is perfect to meet or exceed our industrial and ventilation customers’ energy efficiency requirements. We also focus on our customers’ cost effectiveness. This is why our R&D Team designed each of the 3 varieties of the D-Series not only with highest durability but also with optimal material input in mind.

  • punk-2016-015_d-serie_online-banner_203x230px_160928_v02The Dlight made of aluminum is available in tapped version for a diameter range of 225-630 mm (9″ – 25″). It is preferably used in pressure ranges from 1000 – 1500 Pa (4 – 6 in. WG – AMCA Class I) with a tip speed of up to 55 m/s (180 fps). This fan wheel stands up successfully against the already available competitors’ products.
  • The Dclassic works best in a pressure range from 1.500-2.500 Pa (6 – 10 in. WG – AMCA Class II) and is available in a diameter range of 225 – 1000 mm (9″ to 39 3/8″). This welded steel design with a maximum tip speed 75 m/s (246 fps) is powder coated by default and comes with the well proven taperlock system.
  • The diffuser series would not be complete without the Dprime made of aluminum for a performance range of 2500-4000 Pa (10 – 16 in. WG – AMCA Class III), additionally optimized with regards to acoustics by airfoiled blades. This fan wheel is currently still in test stage and will be presented to the public in spring 2017.

Being Sales Director of the punker group, I am firmly convinced that this new series with all its features provides an attractive product range that enables our customers to meet the current requirements for energy efficiency but also the costs resulting from these new requirements. With its three different types  light, classic and prime the D-Series offers a big variety of applications and combines a lot of benefits in one single product family: super silent, absolutely efficient, extremely robust, surprisingly small and exceedingly lightweight.

I am very much looking forward to show you all these benefits of our new wheel series in a face-to-face conversation. Meeting opportunities will be for example at the AHR Expo in Las Vegas or during the ISH in Frankfurt, Germany. Or feel free to contact our Sales Team at your earliest convenience.

I would like to take the opportunity to express my sincere thanks to the whole punker team as well as for demonstrating amazing team spirit by developing these fantastic new products.
