Abstract

Abstract An apparatus for use with a multi-station workspace including a predetermined number of core walls which define an enclosed core. The core walls include an inlet at or below a predetermined height. The apparatus includes a platform positioned in the core at a location above the predetermined height substantially separating the core into a lower air intake chamber and an upper air discharge chamber. The platform further includes a filter in the lower chamber and a blowers drawing air from the intake chamber through the filter to the upper chamber. Finally, a core lid is positioned at the top of the core and includes air discharge vents. The discharge vents are side vents proximate each of the core walls for discharging air in a substantially horizontal direction out from each of the core walls to form an envelope of clean, filtered air for the workspace.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 137 words
A work station array including at least one workspace defined in part by side walls, comprising: an enclosed core associated with said work station array and including air inlet means for drawing air into said core at or below a predetermined height and having means for circulating and filtering air through said core; and air discharge means at the upper end of said core for discharging air solely in a predetermined common plane out from said core and at a distance above said height to cooperatively form an envelope of filtered air surrounding a space defined (i) in part by said side walls and said core wall, and (ii) in part by air flow out of said air discharge means and into said air inlet means, whereby an individual in said workspace is enclosed in filtered air.
Claim 2
Dependent Claim 137 words
A work station array including at least one workspace defined in part by side walls, comprising: an enclosed core associated with said work station array and including air inlet means for drawing air into said core at or below a predetermined height and having means for circulating and filtering air through said core; and air discharge means at the upper end of said core for discharging air solely in a predetermined common plane out from said core and at a distance above said height to cooperatively form an envelope of filtered air surrounding a space defined (i) in part by said side walls and said core wall, and (ii) in part by air flow out of said air discharge means and into said air inlet means, whereby an individual in said workspace is enclosed in filtered air.
Claim 3
Dependent Claim 23 words
The array of claim 1 where said core has a solid core top directing all of said air to said air discharge means.
Claim 4
Dependent Claim 14 words
The array of claim 2 wherein said air filter means includes a HEPA filter.
Claim 5
Dependent Claim 29 words
The array of claim 2 which further includes spacing means for elevating said core top above the core walls by a distance sufficient to define said air discharge means.
Claim 6
Dependent Claim 44 words
The apparatus of claim 4 wherein said air circulating and filtering means includes a blower having sufficient capacity to provide approximately thirty air changes per hour for the region included by a thirteen foot circle having its axis at the center of said core.
Claim 7
Dependent Claim 18 words
The apparatus of claim 5 wherein said blower has at least a 300 cubic feet per minute rating.
Claim 8
Dependent Claim 21 words
The apparatus of claim 6 wherein said blower is the sole air moving means for circulating air through said enclosed core.
Claim 9
Dependent Claim 38 words
The apparatus of claim 1 wherein said means for circulating and filtering air includes a first prefilter means for removing larger particulates from the air and further includes a second prefilter means for removing odors from the air.
Claim 10
Independent Claim 119 words
A method for providing a clean air workspace for individuals, comprising the steps of: forming a work station core and providing side walls extending from said core to define in part at least one work station, said core having an air inlet at or below a predetermined height; filtering air in said core through filter means to provide clean air in said core; and discharging said clean air from said core from air discharge means solely in a predetermined common plane above said height and proximate the top of said core to provide an envelope of air from said air discharge means out over said workspace and into said air inlet to further define in part said work station.
Claim 11
Independent Claim 119 words
A method for providing a clean air workspace for individuals, comprising the steps of: forming a work station core and providing side walls extending from said core to define in part at least one work station, said core having an air inlet at or below a predetermined height; filtering air in said core through filter means to provide clean air in said core; and discharging said clean air from said core from air discharge means solely in a predetermined common plane above said height and proximate the top of said core to provide an envelope of air from said air discharge means out over said workspace and into said air inlet to further define in part said work station.
Claim 12
Dependent Claim 25 words
The method of claim 9, wherein said core has a solid core top directing substantially directing all of said air to said air discharge means.
Claim 13
Dependent Claim 13 words
The method of claim 10 wherein said filter means includes a HEPA filter.
Claim 14
Dependent Claim 36 words
The method of claim 11 wherein said air is discharged to provide approximately thirty air changes per hour for the region included by a thirteen foot circle having its axis at the center of said core.
Claim 15
Dependent Claim 23 words
The apparatus of claim 12 wherein said air is discharged with a blower having at least a 300 cubic feet per minute rating.
Claim 16
Dependent Claim 22 words
The method of claim 12 including prefiltering air in said core to remove larger particulates from air prior to discharging said air.
Claim 17
Dependent Claim 19 words
The method of claim 14 including prefiltering air in said core to remove odors prior to discharging said air.
Claim 18
Dependent Claim 133 words
A work station array including at least one workspace defined in part by side walls, comprising: an enclosed core associated with said work station array and including air inlet means for drawing air into said core at or below a predetermined height and having means for circulating air through said core; and air discharge means at the upper end of said core for discharging air solely in a predetermined common plane out from said core and at a distance above said height to cooperatively form an envelope of air surrounding a space defined (i) in part by said side walls and said core wall, and (ii) in part by air flow out of said air discharge means and into said air inlet means, whereby an individual in said workspace is enclosed in air.
Claim 19
Dependent Claim 133 words
A work station array including at least one workspace defined in part by side walls, comprising: an enclosed core associated with said work station array and including air inlet means for drawing air into said core at or below a predetermined height and having means for circulating air through said core; and air discharge means at the upper end of said core for discharging air solely in a predetermined common plane out from said core and at a distance above said height to cooperatively form an envelope of air surrounding a space defined (i) in part by said side walls and said core wall, and (ii) in part by air flow out of said air discharge means and into said air inlet means, whereby an individual in said workspace is enclosed in air.
Claim 20
Dependent Claim 23 words
The apparatus of claim 16 where said core had a solid core top directing all of said air to said air discharge means.
Claim 21
Dependent Claim 29 words
The array of claim 16 which further includes spacing means for elevating said core top above the core walls by a distance sufficient to define said air discharge means.
