  • Patent number: 9878274
    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 first side panel and a second side panel having parallel first edges oriented perpendicular to a flow direction through the filter. A plurality of filter elements are arranged in at least two pairs of vees extending between the first and second housings. The side panels and the filter elements comprise a unitary disposable filter, wherein at least three filter elements have a unique orientation relative to the flow direction.
