ABSTRACT:
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.
