FILTER ELEMENT Russian patent published in 2017 - IPC B01D27/00 B01D29/11 

FIELD: process engineering.

SUBSTANCE: invention is intended for filtration. The filter element comprises a filter filler disposed circumferentially around the longitudinal axis of the filter element and along it, and a guide structure attached to the filter filler and defining the mounting location of the filter element. In cross-section the guide structure has a non-circular and / or an asymmetrical shape relative to the longitudinal axis, and in its first cross-section it has the first guide surface displaced radially relative to the longitudinal axis. The guide structure comprises the second guide surface displased radially relative to the first guide surface. The filter in assembly comprises the filter element, the first guide structure and the mounting structure comprising the second guide structure, in the second cross-section having non-circular and / or an asymmetrical shape that is aligned with the non-circular and / or asymmetrical relative to the longitudinal axis shape of the first guide structure. The second guide structure comprises at least one portion of the central tube extended around and along the longitudinal axis within the filter filler.

EFFECT: invention provides filter installation accuracy.
