GFH
Protective Filter for gas applications up to 1,050 bar
Features
The GFH is a fitting filter that can be used not only for onboard hydrogen filtration but also for stationary gas applications. The GFH protective filter was developed for hydrogen filtration. In this area of application, which involves the highest of cleanliness requirements, together with our GF1 working filter, it completes our comprehensive filtration concept and has already proven its reliability and performance capability.
As a protective filter, the duty of the GFH is the reliable retention of impurities that are created by downstream equipment (e.g. the wear of components and materials of seals) and which can lead to the failure of important system components. The GFH provides effective protection for downstream analog components, e.g. non-return or control valves, dispensers (petrol nozzles) and filling spouts on the vehicle, thus making a significant contribution to the reduction of down times. Installation takes place immediately in front of the component to be protected. As an option, the filter element, particularly with onboard solutions, can be integrated directly in the housing of the respective component and thus adapted optimally to the respective application.
