I have a standard 2HP DC with the usual upper and lower cloth bag. However, I note that when using this DC to collect the router and saw shavings from solid surface countertops that the fine dust soon clogs the upper bag, thus reducing the DC's efficiency. For just about $200, I could convert my DC to a canister filter on the top and plastic bag on the bottom. According to Penn State Industries catalog, the canister dramatically improve a DC's efficiency by providing much more filter area and a finer filter for flour-like dust (such as that produced from cutting and milling solid surface). Is anyone using the PSI canisters or those offered by Delta and Jet and do DCs with canisters perform as promised (and better than conventional cloth bags)?
Thanks in advance for your input.
