Overview of Filter Systems

In the design of filter systems, the various ambient conditions encountered require distinction between static and self-cleaning filter systems (i.e., for depth filtration and surface filtration, respectively).

The term “static filter systems” is used to designate those systems that utilize depth and storage filter technologies. After a prescribed limit pressure difference is reached, this type of filter must be removed and replaced by new media. The great selection of filter types available allows employment of an optimal combination for each application case.

Self-cleaning filter systems utilize inertial, impingement, or surface-filtration techniques. They require extremely little service, and enable long lifecycles, despite high concentrations of dust or sand.

Pulse filters feature cleaning of the filter medium by a blast of compressed air after a prescribed differential pressure has been reached. These filters are especially effective in arid zones with high dust concentrations, as well as in regions with sandstorms. They enable long lifecycles and are characterized by comparatively low pressure differences.
