Centro de Documentacion de Fundación MAPFRE - An Empirical model for estimating the collection efficiency of dust-mist respirators

Notes: Sumario: This paper compares experimental measurements of filter performance with predictions of aerosol collection by dust-mist respirators using the single fibre efficiency model and an empirical model developed by the authors. The former, a theoretically-based semi-empirical model, indicates that mechanical phenomena such a impaction, interception and diffusion are responsible for omly a fraction of the collection efficiency of dust-mist respirators, i.e. 30-70% depending of particle sizeRelated records: En: The Annals of occupational hygiene. - Oxford [etc.]. - nº 2, April 1993 ; p. 135-150Materia / lugar / evento: Higiene industrial Contaminantes químicos Aerosoles Equipos respiratorios Filtros Control de contaminantes Métodos de control Otros autores: Evans, John S.
