Abstract

A popular flat-topped inlet used for the collection of atmospheric particulate matter was modified to reduce water intrusion during rain and snow events. Simple alterations in the intake region of this inlet were made, including a larger drain hole, a one piece top plate, and louvers.Wind tunnel tests were performed at 24 km/h for fine particle aspiration and at 2, 8, and24 km/h for coarse particle sampling characteristics of the modified design. The laboratory evaluations of this inlet for line (PM2.5) and coarse (PM10) particle sampling demonstrated that the aspiration characteristics of this inlet were identical to those of the original inlet. This inlet should greatly reduce, if not totally prevent, the intrusion of precipitation. Further, sampling effectiveness test results suggest that the modified inlet could be substituted for the original inlet where the original inlet is partof a designated reference or equivalent method sampler for PM10.
