« Part 1: Dust Collector Upgrade – Pt 1 – Upgrading to HEPA Cartridge Filter Part 2 of Dust Collector Testing and Upgrade series no next part

After doing a complete rebuild of the system with the HEPA filter from Wynn Environmental, I run it through the same battery of tests I did in Part 1. This resulted in a 257% increase in cfm! The results are truly fantastic. If you have any questions on this build of the system, please leave a comment or PM me, as I truly welcome your questions and comments.. Thanks for watching!

Thanks John. Yes, it came out very well. And it has made a huge difference in the DC for my tablesaw and bandsaw. Have not tried the jointer or planer yet however.

Very nice study. One nit pick: isn’t the new result actually 257% “of” the old result, yielding a 157% -increase- over the old result? For example, doubling the CFM would be a “100% increase”, and not a “200% increase.

One thing I took away from this is that the dust deputy really was not that bad as far as reducing CFM as long as there are not extra hoses, and the remaining hoses are sized right. Based on the first video, I was really worried the dust deputy introduced too much drag, and I am glad to see that’s not so.

Hi Andrew,

I understand your explanation of the increase and how you look at the numbers. The way I’m looking at it is that the original number is 214 cfm, so 100% of that particular number is 214. The 257% number is 2.57 times the original cfm. I guess it depends on how you look at it, and we would both be correct.

Anyhow, I’m glad you took something away from the video and the rebuild, and hope that it will help you if you decide to do something like this with your own setup. Thanks for the comments!

Nice work, interesting video I love it when someone shows the basis for their claims. If John says it’s workable you can take it to the bank.

Thanks, Guy. When I saw the percent increase, I first thought of something of similar phrasing, like “the price increase is 10%”, aka 1.10x. Anyway, it’s all good because you provided the raw numbers with proof, and that’s what matters.

I am now convinced I should get a anemometer based on your videos. I really hope to do similar studies with my existing Festool vac, a shop vac, with/without smaller dust deputy, and hopefully in the near future, 100% custom DIY shop vac.

Really appreciate your time in giving us this info Guy. I’ll be getting my Wynn, and doing some piping changes myself soon.
