ABSTRACT:
A filter media (10) of the type supported across a fluid flow passage for collecting particulate out of the fluid and subsequently being moved out of the flow passage after becoming congested with particulate. The filter media (10) includes a top layer (12), a middle layer (14), and a bottom layer (16). The middle layer (14) comprises a support web (18) formed by entwined cotton fibers (20), and a mesh (22) supported by the web (18) formed by entwined glass microfibers (24). The middle layer (14) forms a plurality of minute pore passages between adjacent glass microfibers (24) and cotton fibers (20). The top layer (12) is a nonwoven wet laid polyester material for preventing adherence of the fiber media (10) to the edges of the fluid flow passage. The bottom layer (16) is a nonwoven spun bonded polyester material highly resistant to tear for supporting the filter media (10) while it is moved out of the flow passage.
