ABSTRACT:
A selective and effective collection of noninhalable and/or nonrespirable particulates employs inertial impaction to separate particles larger than a specified size from smaller particulates in an airstream and to collect them on a moving adhesive collection surface. A unique U-type impaction configuration is used.
