Material Air Shower

Air showers are specialized enclosed antechambers which are incorporated as entryways of cleanrooms and other controlled environments to reduce particle contamination. Air showers utilize high-pressure, HEPA- or ULPA-filtered air to remove dust, fibrous lint and other contaminants from personnel or object surfaces.Air Shower is a self-contained chamber that minimizes particulate matter from entering or exiting the cleanroom and other controlled environments. Personnel and materials entering or exiting the controlled environment are "scrubbed" by high-velocity HEPA- or ULPA-filtered air.Abstract. The discovery of extensive air showers by Rossi, Schmeiser, Bothe, Kolhörster and Auger at the end of the 1930s, facilitated by the coincidence technique of Bothe and Rossi, led to fundamental con- tributions in the field of cosmic ray physics and laid the foundation for high-energy particle physics.
