I acquired a Wolf WD20 wet/dry vac (of unknown vintage), couple of years ago from local charity shop. I tried to clean the foam filter around the motor intake and it disintegrated. Couldn't find anything online to fit it.
The existing filter is homemade from a sheet of foam (approx) 120mm x 400mm x 20mm thick. The two 120mm edges are gorilla taped together, to form a tube. What sort of foam do I need and best place for supply. Thanks in anticipation.
