Abstract

A V-bank air filter having a high air flow rate with low pressure drop is provided. In one embodiment, a V-bank filter includes a housing having a first pair and a second pair of pleated filter elements arranged in a vee configuration and comprising a unitary disposable filter. A centerline defined by the first pair of pleated filter elements defines an acute angle with a centerline defined by the second pair of pleated filter elements.

Claims

1. A V-bank filter comprising:

a first pair of pleated filter elements arranged in a vee configuration;

a second pair of pleated filter elements arranged in a vee configuration; and

a housing comprising;

a first side panel;

a second side panel disposed opposite the first side panel, wherein sides of the V-bank filter are defined by the first and second side panels;

an air filter inlet defined between upstream edges of the first and second side panels; and

an air filter outlet defined between downstream edges of the first and second side panels; and

wherein edges of the first and second pairs of pleated filter elements are secured to the first and second side panels, the housing and filter element pairs comprising a unitary disposable filter, wherein a centerline defined by the first pair of pleated filter elements defines an acute angle with a centerline defined by the second pair of pleated filter elements and wherein the flow direction through the filter inlet is substantially parallel to a flow direction through the filter outlet.

2. The V-bank filter of claim 1, wherein the housing further comprises:

a first spacer coupling the first and second panels, the first spacer having the first pair of pleated filter elements sealed thereto; and

a second spacer coupling the first and second panels, the second spacer having the second pair of pleated filter elements sealed thereto.

3. The V-bank filter of claim 2, wherein the first spacer further comprises:

an elongated tubular member;

a flange extending from the tubular member to a lip, the lip, flange and tubular member forming a trough for receiving an edge of the pleated filter element; and

a notch formed in the elongated tubular member.

4. The V-bank filter of claim 3, wherein the first and second side panels further comprise:

a feature that mates with opposite ends of the elongated tubular member.

5. The V-bank filter of claim 1, wherein the housing further comprises:

a first handle accessible from an interior side of the first side panel; and

a second handle accessible from an interior side of the second side panel.

6. The V-bank filter of claim 5, wherein the first handle does not provide a leak path through the first side panel.

7. The V-bank filter of claim 5, wherein the first handle is an elongated recess formed in but not through the first side panel.

8. The V-bank filter of claim 1, wherein the housing further comprises:

a plurality of blind clip retaining features.

9. The V-bank filter of claim 8, wherein the blind clip retaining features comprises:

a blind slot formed in the housing, the slot having a front wall adjacent an edge of the housing, the front wall perpendicular to a centerline of the filter; and

a notch formed in the housing between the slot and the edge of the housing.
