Claim 2

A self-contained portable enclosure for housing a portable piece of electronic equipment in an uncontaminated environment, comprising: a sealed enclosure having front, back, side, top and bottom wall portions; a first outside opening contained in one of said front, back and side wall portions for allowing outside air to enter said sealed enclosure; an air cleaner system sealingly secured to said wall portion directly behind said first outside opening for cleaning said air entering said sealed enclosure; a cable access box mounted to one of said front, back and side wall portions inside said enclosure, said cable access box including a plurality of layers of foam material through which said cables pass to reach said equipment, such that cables may enter said enclosure while still maintaining the uncontaminated environment of the inside of said enclosure; and a fan mounted to one of said front, back and side wall portions adjacent said first outside opening, said fan being mounted inside said enclosure and in front of a second outside opening such that all air entering the inside of said enclosure must pass through said air cleaner system and be exhausted through said second outside opening.

Claim 3

The self-contained portable enclosure of claim 1, wherein one of said back and side walls is hingedly, sealingly, attached in order to provide access to the inside of said enclosure.

Claim 4

The self-contained portable enclosure of claim 1, further including electronic control circuitry for operating said air cleaner system.

Claim 5

The self-contained portable enclosure of claim 1, wherein said air cleaner system is an electronic air cleaner.
