filter comprises a housing with a lid. It contains at least one filter through which dust laden air or gas passes, under suction from the inlet to the outlet. When it is required to remove the filter, part of the cover is removed and the filter falls into the plastic bag. Any remaining material on the grid is sucked out. Subsequently the pipe is disconnected and the top reaction is removed. The bag is then gathered up and removed. |
