An adjustably directable clean air delivery supply assembly which provides clean air for use in weather protected environments. This assembly is, doorway passable and rollably positioned, to be utilized where activities require very clean air per strict specifications. When located, the device can quickly be unfolded and positioned for operation to produce clean air in the desired direction at minimal-eddy producing airflow. Surrounding unfiltered air is drawn in just above floor level through a pre-filter into a airtight lower hollow housing, which contains an interior powered air moving assembly, and discharged upwardly into the tower hollow housing which is supported on top of the lower hollow housing. Secured to the tower hollow housing is an adjustable telescoping height and rotatable positioning structural tube, which receives and directs the air upwardly through a self-sealing bellows into the top final filter hood assembly. The bellows encapsulates a fully adjustable, interconnecting, angularly adjustable, positioning hinge. The pre-filtered air then passes through a final filter such as a high efficiency particle arrestor type air filter. The final filtered air then is discharged in a desired direction at a selected volume into a shrouded or unshrouded area. The top final filter hood assembly is movable through one hundred eighty degrees of vertical arc, horizontally rotatable, and can be raised or lowered for operation, or folded against the lower hollow housing for storage. This self-contained clean air supply assembly can be transported, adjusted, and reused without recertification testing, when it is handled and operated properly.

[ What is claimed is:] [1.] A rollably positioned, passable through doorways, adjustably directable clean air supply assembly, for use in any weather controlled environment, which directs a controlled amount of clean grade air through an adjustably oriented top hood assembly which contains a sealed final filter that filters the air and allows the discharge of the air at minimal-eddy creating air velocities for improved air quality levels, which creates certifiable cleanrooms, clean zones, improved recirculated air quality within an given area, where an activity is being undertaken, which requires very clean air per strict specifications, comprising:a) a lower hollow housing serving as a plenum to receive, near floor level, horizontally flowing air, through an entry in the front thereof and to discharge, at an exit in the top thereof, vertically flowing air, and also serving as a support for a front pre-filter assembly, an interior powered air moving assembly, a bottom rollable support assembly, and a tower housing, serving in turn as a plenum to receive air flowing through the exit in the top of this lower hollow housing;b) a front pre-filter assembly positioned on the lower hollow housing in front of the entry thereof to pre-filter the incoming room air;c) an interior powered air moving assembly positioned in the lower hollow housing and supported thereby, to draw air in through the pre-filter and to redirect the pre-filtered air up through the exit of this lower hollow housing, serving as a plenum;d) a bottom rollable support assembly secured to the lower hollow housing at the bottom thereof;e) a tower hollow housing serving as a plenum to receive, guide and discharge the pre-filtered air flowing up through the exit in the top of the lower hollow housing, and being firmly supported by the lower hollow housing, and also serving as a support for: a telescoping structural tube, which in turn serves as a plenum to receive the pre-filtered air leaving the tower hollow housing; also for an adjustable positioning subassembly used in maintaining the selected telescoping height and any partially rotated position of a telescoping structural tube; and also for an electrical control subassembly utilized in selectively operating the interior powered air moving assembly;f) a telescoping structural tube serving as an adjustable height plenum to receive pre-filtered air leaving the tower hollow housing and to direct this air upwardly, while being movably supported on the tower hollow housing for up and down adjustments and partial rotary adjustments, and also serving as a support both for a tilt adjustment assembly, used in arcuately moving, stopping, and holding, a top filter head assembly, and for a self-sealing bellows surrounding a tilt adjustment assembly;g) an adjustable positioning subassembly used in determining the telescoping height of the telescoping structural tube serving as an adjustable height plenum and thereby serving in changing the height and any partially rotated position of a top filter head assembly;h) an electrical control subassembly utilized in selectively operating the interior powered air moving assembly;i) a tilt adjustment assembly secured in part to the telescoping structural tube and also secured in part to a top filter head assembly, and selectively adjusted to arcuately move, stop, and/or hold a top filter head assembly;j) a self-sealing bellows, serving as a plenum, surrounding the tilt adjustment assembly and secured at the lower end thereof to the telescoping structural tube, and arranged to be secured at the higher end thereof to a top filter head assembly, to guide the flow of the pre-filtered air around the tilt adjustment assembly enroute to a top filter head assembly;k) a top filter head assembly secured to the tilt adjustment assembly and also to the bellows, and having a high efficiency particle arrestor type filter, to receive the pre-filtered air from the bellows, and to cleanly filter this pre-filtered air, before this finely cleaned air is specifically directed in a desired flow path through a designated volume, where specified clean air is needed.
