摘要:
A device for replacing the air filter (2) of a safety chamber comprises a tubular body (1) having one end fixed in a tight sealing manner to the filter (2) and the other end fixed in a tight sealing manner to a collar (15) belonging to the cabinet. A pair of sleeves (3) accessible from the outside is fixed to the tubular body (1). The filter (2) is replaced by sealing together, in at least two areas, the walls of the tubular body (1); cutting the tubular body (1) between the sealed areas; inserting the portion of tubular body (1) integral with the collar (15) into a second tubular body (1) integral with a second filter (2); fixing the second tubular body (1) in a tight sealing manner to the collar (15); removing from the collar (15), by means of the pair of sleeves (3), the previously sealed portion of tubular body (1), compressing it and placing it in the second tubular body (1).
