A tunnel washer that includes fluid exhaust paths that are optimized to minimize fluid transfer between chambers of the washer and minimize heat loss from each chamber of the washer. The fluid exhaust paths also facilitate uniform vapor evacuation from each chamber of the washer. The tunnel washer also includes spaced-apart double wall curtains for isolating chambers of the tunnel washer to prevent fluid and heat transfer therebetween, and to the exterior of the tunnel washer. The double wall curtains include surfaces that inhibit the curtains from sticking together during operation of the tunnel washer. The tunnel washer also includes an air manifold that provides uniform drying efficiency for articles of varying dimensions.

1. An apparatus for drying articles following a washing operation, the apparatus comprising: a source of pressurized air;an air tube in fluid communication with the source of pressurized air, said air tube emitting the pressurized air toward the articles; andat least one bias member having an end connected to said air tubewherein said at least one bias member, said pressurized air, and a weight of said air tube, exclusively, apply forces to said air tube causing said air tube to maintain a distance D above an upper surface of the article when said pressurized air is exhausted from said plurality of nozzles of said air tube. 2. An apparatus according to claim 1, wherein said air tube includes a plurality of nozzles. 3. An apparatus according to claim 1, wherein said apparatus further comprises a pair of arms for supporting said air tube, wherein a first end of said arms is pivotally connected to a support member. 4. An apparatus according to claim 1, wherein said at least one bias member is a spring. 5. An apparatus according to claim 1, wherein said drying chamber further comprises: a sump disposed at a lower portion of the drying chamber for collecting liquid removed from said article by said pressurized air. 6. An apparatus according to claim 1, wherein said drying chamber further comprises: a fluid exhaust pathway located between an interior of the drying chamber and an exterior of the drying chamber, the fluid exhaust pathway being isolated from fluid dispensing devices;a first curtain located between the fluid exhaust pathway and the exterior of the drying chamber; anda second curtain located between the fluid exhaust pathway and the interior of the drying chamber, the second curtain mounted generally parallel to the first curtain at a location spaced from the first curtain, wherein the first curtain and the second curtain isolate the interior of the drying chamber from the exterior of the drying chamber to hinder fluid from exhausting to the exterior of the drying chamber. 7. An apparatus for drying articles in a drying chamber of a tunnel washer, the drying chamber including a conveyor belt for conveying articles therethrough, the apparatus comprising: an air tube in fluid communication with a source of pressurized air, said air tube including a plurality of nozzles for providing streams of pressurized air;an arm having a first end pivotally mounted within said drying chamber and a second end for supporting said air tube; andat least one bias member having an end connected to said air tube,wherein said at least one bias member, said streams of pressurized air, and a weight of said air tube, exclusively, apply forces causing said air tube to maintain a distance D above an upper surface of the article being dried in said drying chamber when said streams of pressurized air are exhausted from said plurality of nozzles of said air tube. 8. An apparatus according to claim 7, wherein said at least one bias member is a spring. 9. An apparatus according to claim 7, wherein said drying chamber further comprises: a sump disposed at a lower portion of the drying chamber for collecting liquid removed from said article by said pressurized air. 10. An apparatus according to claim 7, wherein said drying chamber further comprises: a fluid exhaust pathway located between an interior of the drying chamber and an exterior of the drying chamber, the fluid exhaust pathway being isolated from fluid dispensing devices;a first curtain located between the fluid exhaust pathway and the exterior of the drying chamber; anda second curtain located between the fluid exhaust pathway and the interior of the drying chamber, the second curtain mounted generally parallel to the first curtain at a location spaced from the first curtain, wherein the first curtain and the second curtain isolate the interior of the drying chamber from the exterior of the drying chamber to hinder fluid from exhausting to the exterior of the drying chamber. 11. An apparatus for drying articles in a drying chamber of a tunnel washer, the drying chamber including a conveyor belt for conveying articles therethrough, the apparatus comprising: a source of pressurized air;an air tube in fluid communication with the source of pressurized air, said air tube emitting the pressurized air toward the articles, said air tube moveable between a first position and a second position; andat least one bias member having an end connected to said air tube,wherein said air tube is in said first position and said at least one bias member and a weight of said air tube, exclusively, apply forces to said air tube causing said air tube to maintain a first distance above said conveyor belt when said pressurized air is not exhausted from said plurality of nozzles, andwherein said air tube is in said second position and said at least one bias member, said pressurized air, and said weight of said air tube, exclusively, apply forces to said air tube causing said air tube to maintain a second distance above an upper surface of the article when said pressurized air is exhausted from said plurality of nozzles of said air tube. 12. An apparatus according to claim 11, wherein said at least one bias member is a spring. 13. An apparatus according to claim 11, wherein said drying chamber further comprises: a sump disposed at a lower portion of the drying chamber for collecting liquid removed from said article by said pressurized air. 14. An apparatus according to claim 11, wherein said drying chamber further comprises: a fluid exhaust pathway located between an interior of the drying chamber and an exterior of the drying chamber, the fluid exhaust pathway being isolated from fluid dispensing devices;a first curtain located between the fluid exhaust pathway and the exterior of the drying chamber; anda second curtain located between the fluid exhaust pathway and the interior of the drying chamber, the second curtain mounted generally parallel to the first curtain at a location spaced from the first curtain, wherein the first curtain and the second curtain isolate the interior of the drying chamber from the exterior of the drying chamber to hinder fluid from exhausting to the exterior of the drying chamber.
