The bag filters ‘do what is says on the packet’ but it is never enough and the cartridge filter is a must if you want to keep healthy.
Internal inspection of my cartridge filter indicated that the paddle movement direction was not important, but I decided that it was inadvisable to keep altering the direction. I put a direction ‘arrow’ on the top surface of the Cartridge to remind me, and anyone else who might use my workshop, which way to rotate the handle.
Operating the paddle will depend on the use you give the extractor. I only use mine when sanding my turnings so usually do it about once an month - unless I am doing a ‘production run’ with plenty of sanding. (Probably once a week would be a good habit to get in to.)
Happy dust free working. Philip.
