Einhell 30 litre Dust Bags for wet & dry vacuum cleaners. Used to collect fine and dry dirt, which keeps the vacuum cleaner's pleated filter clear for longer, so suction power is maintained for longer. NOT suitable for vacuuming liquids. Can be used with all Einhell Wet & Dry Vacuum Cleaners with a 30-litre container. The vacuum bag is simply placed in the collecting container and the vacuum nozzle is connected to the bag's opening (Ø 65mm). Ref: UTTK7763
