Abstract

A filter arrangement includes a filter element, a frame construction secured to the filter element, and a handle member secured to the filter element. In preferred embodiments, the handle member is secured to the frame construction. Preferably, the filter element includes a central core member, wherein fluted filter media is coiled around the central core member. Preferably, the central core member includes a plurality of corrugations, wherein the corrugations mateably engage at least some flutes. Preferably, the handle member is integral with the central core member, and also includes a fastening member for connection to a frame construction on the filter element. Methods for cleaning air and servicing an air cleaner preferably include constructions as described herein.

Claims27

Dependent claims

A filter arrangement comprising a filter element having opposite first and second ends;

said filter element comprising a plurality of flutes;
each of said flutes having a first end portion adjacent to said filter element first end, and a second end portion adjacent to said filter element second end;
selected ones of said flutes being open at said first end portion and closed at said second end portion;
and selected ones of said flutes being closed at said first end portion and open at said second end portion;
and a frame construction secured to said filter element adjacent to said second end;
the filter arrangement being characterized by:
(a) a handle member is secured to said filter element adjacent to said first end;
(b) a board is at least partially extending into said filter element;
said board including:
(i) first and second opposite ends;
(ii) first and second opposite side edges extending between said board first and second opposite ends;
(iii) a first projection axially extending from said first end of said filter element;
(A) said first projection being oriented closer to said first side edge than to said second side edge;
and
(iv) a recessed portion adjacent to said first projection;
and
(c) said frame construction includes at least one support brace extending at least partially over one of said first and second ends of said filter element.
