  • Universal inlet for airborne-particle size-selective sampling
    Patent number: 5412975
    Abstract: A universal airborne-particle size-selective inlet (10) for separating particles (82) larger than a cut size from particles (84) smaller than the cut size is disclosed. The larger particles (82) are separated by inertial collection as they are drawn into the apparatus (10) in an air stream (78) which exits jet orifices (46) aligned with collector holes (34) leading to closed stagnation chambers (24). The larger particles (82) pass through the collector holes (34) and into the stagnation chambers (24) where they remain. The smaller particles (84) are carried by the flowing airstream (78) that turns at, and passes by, the collector holes (34) to an external downstream small particle collection device.
