Device for separating particles from compressible or incompressible fluid and method for cleaning such a device

摘要

An assembly removes particles e.g. microbes from liquids or gases forming e.g. part of a hydraulic or pneumatic power system. The assembly has a main (1) and secondary (2) tube upstream of a filter (13). The secondary tube branches (15) from the main tube to form a feed-back branch with a filter (22). When gas or liquid advances along the main direction of flow (17), lower pressure pertains at the secondary branch inlet (15) than in the subsequent parallel section of the return tube (2). Also claimed is a process to flush the pipes.
