I don't know how to do links off my phone but I googled 200tdi filter and it shows the fins on some but not others??
Mines a Disco air canister is yours Def or disco?
I know the filters are different so maybe def doesn't have them?
Pretty sure it was advertised as discovery but it was an ebay buy so could just have the part missing.
I am familiar with the spinner for dust used to have them on the large compressors i worked on.
Just going to leave it blanked for now.
