Catalogue 9 - STAUFF Filtration Technology

68 www.stauff.com/9/en/#68 D Description STAUFF Return-Line Filters were designed as filters for tank-top mounting, tank-inside mounting or inline mounting. They filter the hydraulic oil before it flows back into the reservoir. This ensures that contamination arising in the components does not get into the tank. Return-Line filters maintain the targeted purity class like Pressure Filters. However, because of their arrangement, they do not fulfil the additional function of a protection filter. In contrast to a Pressure Filter, it only has to withstand low pressure levels. The practical design of STAUFF Return-Line Filters enables quick assembly as well as easy exchange of the filter elements.
