ABSTRACT:
A method and apparatus (1) for control of airborne particulates in enclosed spaces, wherein air is made to flow in parallel airstreams (F), with velocities of the streams selectively graded across the work space (W), so that the integrity of the air flow pattern is better preserved while encountering obstructing objects (6) that lie in its path; and so that any particle introduced into a stream remains entrained and airborne over a longer distance along the clean-to-dirty axis (X). The velocity gradient is achieved by a filtering device (1) comprising a plurality of pleats (25) each pleat having a different surface area.
