I have an older Handley Polishing lathe cabinet w/dust collector,
series 60c. Two size 12x25x2 filters fit in the lower cabinet. The
parts list calls for fiberglass filters. Is there any difference if
using the polyester fiber type filters available now?
Has anyone had any luck increasing the filtration? I would love to
add a Hepa layer. What would be the best filter to use?
Thanks,
Margaret
