And I stand by my statement that your average 3hp cyclone with 5-inch hose (with as little flex run as possible) will do the job just fine. For example, I used to do the trade show circuit with a 12” J/P and bandsaw. We would buy some super-cheapo single-bagger at the beginning of ever show season and just throw it a dumpster by the end of the season, because it was literally falling apart by then. But, it didn’t do a bad job of dust collection in the meantime. Point being, “sure”, you could engineer a DC system to the n-th degree for a home hobby shop that only operates one piece of machinery at a time but I don’t think that’s the same need as, like you mentioned earlier, a large shop that is running multiple machines at the same time. In that case, I agree with you 100%. Hope I am explaining myself OK.

No one least me is engineering anything and jn fact it amazes me when people start trying to do just that with dust extraction. Simply put HP means nothing and it is about time we started to specify dust extractors by impeller size. I am not going to get into debates on DE, use what you want but be aware of what makes a DE perform and what you should be looking for instead of wasting money as Jim did. Knowledge will always allow us to make informed decisions and just because we always did it that way does not mean it is the best way.
