A filter device has a filter housing () with a fluid inlet () for raw fluid, with a fluid outlet () for filtrate and with at least one one-piece or multi-piece filter insert () received in the filter housing (). The filter insert can be cleaned using at least one back-flushing member () in counter-current to the filtration direction. This back-flushing member can, by a fluid-guiding driveshaft () of a rotary drive (), be moved along the inner side () of the respective filter insert () and has, at its end adjacent to this inner side (), a gap-shaped passage opening () that extends parallel to the axis of rotation of the driveshaft () and that discharges into a flow space () fluidically connected to the driveshaft (). The flow space at least partially continuously narrows in the direction of the driveshaft () in a first plane in which the passage opening () lies. In another second plane transverse to the first plane, the flow space () at least partially continuously widens proceeding from the passage opening () in the direction of the driveshaft ().

Filter device

A filter device has a filter housing () having a fluid inlet () for unfiltered matter, a fluid outlet () for filtered matter and at least one filter element () of one or more parts accommodated in the filter housing (). The filter element can be cleaned using at least one backwash element () in counter current to the direction of filtration. The backwash element can be moved by a fluid-conveying drive shaft () of a rotary drive at the inside () of the relevant filter element (). At the end adjacent to this inside (), a gap-shaped passage opening is parallel to the axis of rotation () of the drive shaft () and opens into a flow chamber connected to the drive shaft () in a fluid-conveying manner. The distance between the backwash element () and the adjacent assignable filter element () can be predetermined by an adjustment device ().

Filter apparatus

An apparatus for conditioning of gases, particularly sealing gas, includes a separator unit (), particularly for separating liquids and/or particles from the gas flowing through the apparatus, and a collecting container () for the trapped substances. The separator unit () has a cyclone separator ().

Apparatus for conditioning of gases

A device for separating impurities from gases, such as process gases or hydrogen, includes a filter unit () for separating particulates and fluid media, such as water and/or oil. The filter unit has a coalescing unit () for increasing the drop volume of separated fluid media and a collection unit, preferably in the form of an absorber unit () for binding the separated fluid media.

Separation device for separating impurities from gases

A switching apparatus for a fluid flow with a first fluid-conducting connection () and a second fluid-conducting connection () between first and second treatment devices () has a first pair of switching levers () assigned to first and second distributor valves () and a second pair of switching levers () assigned to third and fourth distributor valves () arranged in different planes. The switching levers () of the first pair can be actuated by an operator without obstruction with the switching levers () of the second pair, and vice versa.

Switching apparatus for a fluid flow

A system for purifying as includes at least one housing () having a first chamber () into which the gas to be purified can flow, and a second chamber () forming a filter chamber, out of which the purified gas exits and with a filter device through which the gas can flow. The filter device has filter media () for separating out solid particles and for dehumidifying the gas for precipitating coalesced fluid. The first chamber () has a cyclone () for pre-dehumidifying the gas, from which dirt particles and fluids can be discharged into a third chamber () of the housing (). The housing () is composed of an upper housing part () with the second chamber () forming the filter chamber, a middle housing part () with a first chamber () having the cyclone (), and a lower housing part () forming the third chamber (), that can be clamped together by at least one tensioning bolt (), forming a closed pressure vessel.
