12. A V-shaped filter comprising:
-
a V-shaped carrier frame; first and second cartridge frames movably mounted to the carrier frame, and movable to an inserted position in the V-shaped carrier frame providing an installed condition with the first and second cartridge frames forming a V-shape such that movement of the first and second cartridge frames to the inserted position traps and seals the first and second filter element cartridges respectively to the first and second cartridge frames in the installed condition, and movable to an extended position extending beyond the V-shaped carrier frame providing a replacement-service condition such that movement of the first and second cartridge frames from the inserted position to the extended position allows removal of the first and second filter element cartridges respectively from the first and second cartridge frames in the replacement-service condition, thereby enabling installation of replacement filter element cartridges; first and second filter element cartridges removably and replaceably mounted to the first and second cartridge frames, respectively; wherein the V-shaped carrier frame has first and second sets of guide track channels receiving the first and second cartridge frames, respectively, along first and second insertion directions, and guiding the first and second cartridge frames along the first and second insertion directions to the inserted position in the installed condition forming the V-shape; and wherein the first and second cartridge frames are inserted along the first and second insertion directions, respectively along first and second travel strokes from a respective beginning of a travel stroke to a respective end of a travel stroke, wherein the first cartridge frame and the first set of guide track channels have a first set of mating detents tactilely engaging each other at the end of the first travel stroke and retaining the first cartridge frame in the inserted position in the installed condition, and the second cartridge frame and the second set of guide track channels have a second set of mating detents tactilely engaging each other at the end of the second travel stroke and retaining the second cartridge frame in the inserted position in the installed condition. - View Dependent Claims (13, 14)

15. A V-shaped filter comprising:
-
a V-shaped carrier frame; first and second cartridge frames movably mounted to the carrier frame, the first and second cartridge frames movable to an inserted position in the V-shaped carrier frame, providing an installed condition with the first and second cartridge frames forming a V-shape such that movement of the first and second cartridge frames to the inserted position traps and seals the first and second filter element cartridges respectively to the first and second cartridge frames in the installed condition, the first and second cartridge frames movable to an extended position extending beyond the V-shaped carrier frame, providing a replacement-service condition such that movement of the first and second cartridge frames from the inserted position to the extended position allows removal of the first and second filter element cartridges respectively from the first and second cartridge frames in the replacement-service condition, thereby enabling installation of replacement filter element cartridges; and first and second filter element cartridges removably and replaceably mounted to the first and second cartridge frames, respectively, wherein the V-shaped carrier frame has first and second sets of guide track channels receiving the first and second cartridge frames, respectively, along first and second insertion directions, and guiding the first and second cartridge frames along the first and second insertion directions to the inserted position in the installed condition forming the V -shape; and wherein the first and second cartridge frames are inserted along the first and second insertion directions, respectively, along first and second travel strokes from a respective beginning of a travel stroke to a respective end of a travel stroke, wherein the first cartridge frame and the V-shaped carrier frame engage each other in locking relation at the end of the first travel stroke at a first releasable mechanical lock locking the first cartridge frame in the inserted position in the installed condition until mechanically released, the first releasable mechanical lock including a first movable locking finger on one of the first cartridge frame and the V- shaped carrier frame and a first slot with a first stop on the other of the first cartridge frame and the V-shaped carrier frame, and wherein the second cartridge frame and the V-shaped carrier frame engage each other in locking relation at the end of the second travel stroke at a second releasable mechanical lock locking the second cartridge frame in the inserted position in the installed condition until mechanically released, the second releasable mechanical lock including a second movable locking finger on one of the second cartridge frame and the V-shaped carrier frame and a second slot with a second stop on the other of the second cartridge frame and the V-shaped carrier frame. - View Dependent Claims (16, 17, 18, 19, 20, 21)
