I have run central vac plastic pipe though the shop. The system collects dust from portable sanders, spray off the top of the blade at the rip saw, miter saw dust, and general shop vacuuming dust. The pipes lead to a 55 gallon drum cyclone, then a shop vac. I have tried shop vacs in series and tandem to increase static pressure, but I would like to do away with the filters.
I am looking for a better vacuum. No filter would be best, because the air goes into a sawdust trailer, out doors. Right now, I need to clean 1/2 cup of very fine dust out of the vac filter every day. So, a hepa filtered vac would just clean the air before it goes into a sawdust trailer. No filter means no filter to clean outdoors in the snow.
It seems like a vac has higher static pressure than a blower. I have other dust collectors on the same machines for the big stuff. The two inch line collecting at the source seems to work best.
I would appreciate any suggestions for a high static pressure vac with no filter.
Thank you
