GF1 High Pressure Filter

Filtration technology for H2 fuel stations up to 1,000 bar


For hydrogen-powered vehicles, the cleanliness and quality of the hydrogen is of great importance. When refuelling vehicles, the fuel stations must deliver hydrogen which is as clean as possible and whithout impurities. This has started a trend for integrating filter systems into the infrastructure of hydrogen fuel stations.

In developing the GF1, HYDAC Process Technology has taken account of this trend which entails a fundamental change in the requirements of filtration systems on hydrogen fuel stations in respect of particle retention, pressure stability and service life. 

In the GF1, Hydac is offering a new technology to ensure the technical cleanliness of hydrogen for hydrogen fuel stations up to 1,000 bar. The combination of a filter housing specially developed for this application and unique filter element technology provides the greatest process stability with the best possible permeate quality. The filter element can be changed in just a few minutes during maintenance, without removing the filter from the gas line.

The design of the GF1 offers the maximum filtration area in the most compact dimensions and is therefore ideal for use on H2 fuel pumps. The extremely robust stainless steel filter elements are noted for their outstanding differential pressure stability and resistance to pressure surges. 

The Chemicron® metal fibre developed by Hydac delivers defined filtration rates and maximum filter integrity. The combination of different filter layers prevents perforation of the filter material during the fuelling process. No resins at all are used in the construction of the filter element, hence electrostatic charging is avoided and operation with aggressive media subject to extreme temperature fluctuations is possible. As a result of the large filter area and the high contamination retention capacity, the service life of the filter elements can be significantly increased and the maintenance costs substantially reduced.
