Filter Technology

The Schwer Fittings in-line filters and screw-in filters are safety filters of in-line design, used to protect critical system components.

Critical components of a system are e.g. valves, ­cylinders, motors, swivel-joints. In general, all critical components are those that contain dynamic seals. Impurities within the medium can cause increased wear due to abrasion, which can lead to leakage or system failure. In order to prevent this, further protection such as filters are highly recommended.

If you need to help to decide whether or not to use a screw-in filter within your system, then please contact us. 

Please note, that a screw-in filter does not replace the main filter of your system. These offer additional protection against residues of the manufacturing ­process (such as swarf, welding residue, aging media and particulate contamination), within the individual components. They also offer a protection against ­contamination which may arise, over time, from ­defective upstream components. These contaminants could lead to catastrophic system failure and unexpected, costly, downtime. Additionally contaminants can increase wear within the system, ­resulting in a shorter service life of the components.
