The suction arms are used in working places where the suction of particulates in various sizes, from powder to larger grains of wood or metal, is mandatory. The arms are mounted and fixed on the wall with the ability to unfold, reaching a radius of 4m in order to cater for the suction in the working area. The fan of the arm can be mounted at the edge of the arm, or can be a separated system for more powerful absorption and ability of filtering at the same time using filter bags.
