Functional principle of in-line filters 

In hydraulic systems, in-line filters are mainly used as pressure line filters in pipelines. However, in-line filters are also occasionally used as return filters. In-line filters are usually available in the following materials: 
  • Aluminum (low-pressure line filters) 
  • Steel/aluminum (medium-pressure line filters) 
  • Steel (high-pressure line filters) 
They consist of a filter head, into which the filter body is screwed. In most applications, in-line filters are equipped with a bypass valve with a defined switching pressure to ensure that the hydraulic system is supplied with fluid even if the filter element becomes saturated. In addition, in-line filters usually include a connection for a service indicator to inform the operator when the filter element is due for replacement. 

Changing the filter element 

To change the filter element, unscrew the filter body from the filter head and replace the saturated filter element with a new one. Then screw the filter body back into the filter head with the specified torque. For this maintenance procedure, the hydraulic system must first be switched off and depressurized. 

Types of in-line filters 

In addition to traditional in-line filters, so-called double-switch filters – or duplex filters – can also be used. These variants consist of a filter head that can accommodate two filter bodies, each containing one filter element. The filter head on these in-line filters includes a changeover valve that makes it possible to switch between the two filter bodies. Thus, when Element A has reached its maximum dirt-holding capacity and needs to be replaced, Element B can be brought online without interrupting the system. This means that either element can be replaced during operation.
