Abstract
A filter bank includes a filter enclosure. A first filter panel and a second filter panel are flexibly joined along respective proximal ends of the first filter panel and the second filter panel by a living hinge. A first sealing gasket extends along a distal end of the first filter panel and forms a first air seal within the filter enclosure. A second sealing gasket extends along a distal end of the second filter panel and forms a second air seal within the filter enclosure. A third sealing gasket extends along the living hinge. A pivoting sealing rail pivots within the filter enclosure to form a third air seal against said third sealing gasket extending along the living hinge.
Claims17
A filter bank, comprising:
- a filter enclosure;
- a first filter panel and a second filter panel flexibly joined along respective proximal ends of the first filter panel and the second filter panel by a living hinge, wherein flexing of the living hinge permits unfolding of the first filter panel and the second filter panel from a folded state in which a distal end of the first filter panel is adjacent a distal end of the second filter panel to a V-shaped state in which the distal end of the first filter panel is separated from the distal end of the second filter panel;
- a first sealing gasket extending along the distal end of the first filter panel and forming a first air seal within the filter enclosure;
- a second sealing gasket extending along the distal end of the second filter panel and forming a second air seal within the filter enclosure;
- a first sealing channel within the filter enclosure;
- a second sealing channel within the filter enclosure, wherein the distal end of the first filter panel is T-shaped and is vertically captured within the first sealing channel, and the distal end of the second filter panel is T-shaped and is vertically captured within the second sealing channel;
- and
- a pivoting sealing rail that pivots within the filter enclosure to form a third air seal along the living hinge.

A filter bank, comprising:
- a filter enclosure;
- a first sealing channel within the filter enclosure;
- a second sealing channel within the filter enclosure;
- a first filter panel and a second filter panel flexibly joined by a living hinge located between a proximal end of the first filter panel and a proximal end of the second filter panel, wherein the first filter panel includes a first T-shaped distal flanged end located within the first sealing channel, and the second filter panel includes a second T-shaped distal flanged end located within the second sealing channel, and wherein flexing of the living hinge permits unfolding of the first filter panel and the second filter panel from a folded state in which the first T-shaped distal flanged end of the first filter panel is adjacent the second T-shaped distal flanged end of the second filter panel to a V-shaped state in which the first T-shaped distal flanged end of the first filter panel is separated from the second T-shaped distal flanged end of the second filter panel;
- a first sealing gasket extending along the first T-shaped distal flanged end of the first filter panel and forming a first air seal within the first sealing channel;
- a second sealing gasket extending along the second T-shaped distal flanged end of the second filter panel and forming a second air seal within the second sealing channel;
- and
- a third sealing gasket extending along the living hinge and forming a third air seal within the filter enclosure,
- wherein the first T-shaped distal flanged end of the first filter panel is vertically captured within the first sealing channel, and the second T-shaped distal flanged end of the second filter panel is vertically captured within the second sealing channel.

A filter bank, comprising:
- a filter enclosure;
- a first sealing channel within the filter enclosure;
- a second sealing channel within the filter enclosure;
- a third sealing channel within the filter enclosure;
- a fourth sealing channel within the filter enclosure;
- a first filter panel and a second filter panel flexibly joined by a first living hinge located between a proximal end of the first filter panel and a proximal end of the second filter panel, wherein the first filter panel includes a first T-shaped distal flanged end located within the first sealing channel, and the second filter panel includes a second T-shaped distal flanged end located within the second sealing channel, and wherein flexing of the first living hinge permits unfolding of the first filter panel and the second filter panel from a folded state in which the first T-shaped distal flanged end is adjacent the second T-shaped distal flanged end to a V-shaped state in which the first T-shaped distal flanged end is separated from the second T-shaped distal flanged end;
- a third filter panel and a fourth filter panel flexibly joined by a second living hinge located between a proximal end of the third filter panel and a proximal end of the fourth filter panel, wherein the third filter panel includes a third T-shaped distal flanged end located within the third sealing channel, and the fourth filter panel includes a fourth T-shaped distal flanged end located within the fourth sealing channel, wherein flexing of the second living hinge permits unfolding of the third filter panel and the fourth filter panel from a folded state in which the third T-shaped distal flanged end is adjacent the fourth T-shaped distal flanged end to a V-shaped state in which the third T-shaped distal flanged end is separated from the fourth T-shaped distal flanged end, and wherein the first filter panel, the second filter panel, the third filter panel, and the fourth filter panel are arranged in a zigzag configuration and are respectively vertically captured by the first sealing channel, the second sealing channel, the third sealing channel, and the fourth sealing channel;
- a first sealing rail that is movable within the filter enclosure between an unsealed position and a sealing position to form a first air seal against the first living hinge;
- and
- a second sealing rail that is movable within the filter enclosure between an unsealed position and a sealing position to form a second air seal against the second living hinge.
