ARGO-HYTOS sets standards in wind power with EXAPOR®MAX 2

In order to improve the power density of the filters, it is necessary to reduce the pressure drop in addition to increasing the dirt holding capacity.
With the help of flow simulations, it has been possible to gain knowledge about the conditions in the pleat channel. Influencing factors significantly responsible for the pressure loss in the pleated filter material could be identified and optimized. The result is a special weaving technique in the production of the new hybrid fabric, which ensures that the pleat channels are kept optimally open. The pressure loss in the fold is thus reduced by up to 50%. In an impressive way, the knowledge gained in the simulation could be put into practice and confirmed by numerous tests.
The reduction of the pressure drop in the filter element by up to 40 %, with the same volume flow, means conversely that with a given pressure drop, an up to 65 % higher volume flow can be realized with the EXAPOR®MAX 2 filter elements.
When designing hydraulic and lubricating oil systems, smaller filter sizes can be used, depending on the application, thus saving weight, resources and costs.
In existing plants, the reduction in pressure drop results in the bypass valve being open less frequently and for a shorter period of time to protect the filter elements. As a result, fewer particles pass through the bypass to the clean oil side and the risk of malfunctions due to unfiltered oil is significantly reduced.
The performance-optimized structure of the new, 3-layer filter material consists of glass and polyester fibers of varying fineness. This novel material mix in the pre-filter and ultra-fine filter materials of the EXAPOR®MAX 2 filter elements makes a major contribution to improving the dirt holding capacity, which has been increased by up to 60 % in the 5 µm(c) filter rating, for example.
