Title:
FILTER MEDIA CONSTRUCTION
Document Type and Number:
WIPO Patent Application WO/2015/155700
Kind Code:
A3
Abstract:
The present disclosure discloses a filter media construction wherein at least two layers of a substantially open spacer and at least two layers of a filter media/material are combined in an alternating sequence and coiled around a core to form at least two distinct, continuous or segmented, coil-shaped fluid flow channels that are contiguous but separated by the filter media in radial direction and extend axially from an inlet side to an outlet side of the filter media construction preventing direct fluid flow between the clean and dirty sides of the filter media construction. The spacer maintains substantially uniform width of flow channels in flow direction providing substantially uniform fluid flow. One flow channel is closed to fluid flow at the inlet side forming the clean side and the other flow channel is closed to fluid flow at the outlet side forming the dirty side of the filter media construction.
