First Claim
1. A filter element comprising:
- (a) a single seamless media pack;
the media pack having first and second opposite ends and first and second lateral sides extending between the first and second ends;
the media pack having pleats extending between the first and second ends;
(i) the media pack having a first cross-section defined between the first and second lateral sides;
(ii) the first cross-section having at least one outward projection that defines an internal radius of at least ¼
inch;
(A) the media pack being fanned around the internal radius, a plurality of the pleats extending around the internal radius in non-touching engagement with each other around the internal radius;
(b) a first end cap secured to the first end of the media pack;
(c) a second end cap secured to the second end of the media pack;
(d) a frame member secured to the first end cap, second end cap, the first lateral side, and the second lateral side; and
(e) a gasket held by the frame member;
the gasket extending along the first end cap, second end cap, first lateral side, and second lateral side.

Abstract
A filter element includes a single seamless media pack having first and second opposite ends and first and second lateral sides extending between the first and second ends. The media pack also has pleats extending between the first and second ends and a first cross-section defined between the first and second lateral sides. The first cross-section having at least one outward projection that defines an internal radius of at least ¼ inch wherein a plurality of pleats of the media pack are fanned around the internal radius. A first end cap is secured to the first end of the media pack while a second end cap secured to the second end of the media pack. Additionally, a frame member is secured to the first end cap, second end cap, the first lateral side, and the second lateral side. A pre-filter is usable with described filter arrangements.
