Installation for dust-free work, especially for the production and checking of electronic components, and method for operating it

Abstract

Abstract 1. Installation for dust-free working, comprising a tight isolator (10), whose wall (12) encloses a closed working volume (14) and having means (15) for intervening within said volume without breaking said wall ; at least one tight container (20) separate from the isolator and which can be connected and linked with the latter by a tight transfer device (22), in order to introduce and extract with respect to the isolator products and equipment ; characterized in that it comprises a closed circuit (24) for particulate purification of the isolator issuing into the latter and having high flow rate ventilation means (32) and filtering means (28) ; a closed circuit (48) for the particulate purification of the container issuing into the latter and having ventilation means (56) and filtering means (52) ; an open circuit (34) for the admission of fresh air into the isolator having an intake pipe (36) equipped wit low flow rate ventilation means (42) and filtration means (40) and a discharge pipe (38) equipped with filtration means (44), the intake and discharge pipes communicating both with the isolator and with the exterior.
