Clean air system

A clean zone kit for forming a clean zone within a clean room;

• the clean room including walls, a ceiling, a floor, an air delivery system which filters particles from the air, and a work surface in the room;
• the air delivery system including a filter, a fan which forces air through the filter, an air return, and duct work connecting the air return to the fan, so that at least some air from the room is recirculated through the filter;
• the work surface being positioned in the room so that the air delivery system forces air over the work surface;
• the clean zone kit including a shield mountable to the ceiling;
• the shield having a front panel, at least one side panel, and at least one clip to hold said front and side panels together;
• said front and side panels being independent of other and being suspended from the ceiling, the front panel having side edges and a bottom edge extending between said side edges;
• said front panel being sized such that its bottom edge is spaced above the work surface when said shield is installed in said clean room;
• said at least one side panel having a front edge and a back edge, said side panel front edge being adjacent one of said front panel side edges;
• said at least one clip connecting said side panel front edge to said front panel side edge;
• said clip being substantially shorter than the edges of said panels;
• the shield defining a zone over at least a part of the work surface, the shield being mountable to the ceiling so that at least a portion of the filter directs filtered air into the zone such that the zone will be a clean zone.

A clean zone kit for forming a clean zone above a work surface within a preexisting clean room;

• the clean room including walls, a ceiling, a floor, an air delivery system which filters particles from the air, and a work surface in the room;
• the air delivery system including an air filter mounted in a wall of the room, a fan which forces air through the filter, an air return, and duct work connecting the air return to the fan, so that at least some air from the room is recirculated through the filter;
• the work surface being positioned in the room against the wall in which the filter is mounted so that the air delivery system forces air over the work surface;
• the clean zone kit including a shield mountable above the work surface to create said clean zone at said work surface;
• the shield including a top panel mounted to the wall in which the filter is located such that at least a portion of the filter is below the top panel and a front panel which depends from the top panel, the front panel having a bottom edge spaced above the work surface;
• the shield in combination with said wall defining a zone over at least a part of the work surface, the shield being mountable to the wall so that at least a portion of the filter directs filtered air into the zone.

A clean zone kit for forming a clean zone above a work surface within a clean room, the clean room having a drop ceiling formed from a ceiling grid and a plurality of ceiling panels supported by said grid;

• the kit including at least a front panel and a bracket assembly to suspend the panel from the ceiling in the clean room;
• the bracket assembly including:
• a bracket having a left half and a right half, each bracket half including an upper U-shaped section sized to accept a portion of the ceiling grid;
• and a leg depending from a bottom of the U-shaped section;
• and
• a clip which is held between the legs of said left and right halves of said bracket, said clip including a first clip leg and a second clip leg;
• and a channel formed in one of said clip legs;
• said channel extending generally perpendicularly to an axis of said clip;
• said kit panel including an enlarged top edge, said enlarged top edge being sized to be received in said clip channel.
