Abstract

Abstract A portable, modular room enclosure having an open end providing horizontal, contaminant-free tunnel type laminar flow for surgery or the like includes mobile means for generating an air flow demountably connected to said enclosure, air supply means in the unit in communication with the air flow generating means for receiving the air flow and converting it to a contaminant-free horizontal laminar flow within the enclosure toward the open end, first and second partitions forming side walls of the enclosure, wherein each partition is demountably connected at one end to said air supply means and at least one retractable side panel slidably mounted on a track connected to each partition wherein the track and panel are in parallel relation with the partition. By extending or retracting the side panels the length of each partition may be selectively changed to accommodate the needs of a surgery theater or the like.
