Abstract

Air filter for spray coating, having: a housing designed for showing a cuboid shape, with a face forming an air inlet and an opposed face forming an air outlet; one or more accordion panels with fold lines, to be accordion folded about said fold and to be located in the housing for forming a filtering barrier; the one or more accordion panels of the filtering barrier having at least one pair of flap portions configured to be folded to form a converging profile followed aeraulically by a trapping chamber formed by one of the accordion panels, and openings forming escape lateral passages of the trapping chamber(s).

Abstract

Air filter (1) for spray coating, comprising: a housing (3) designed for showing a cuboid shape, with a face (5) forming an air inlet and an opposed face (7) forming an air outlet; one or more accordion panels (9) with fold lines (11), to be accordion folded about said fold (11) and to be located in the housing (3) for forming a filtering barrier (8); the one or more accordion panels (9) of the filtering barrier (8) comprising at least one pair of flap portions (15) configured to be folded to form a converging profile followed aeraulically by a trapping chamber (29) formed by one of the accordion panels (9), and openings forming escape lateral passages of the trapping chamber(s) (29).
