Default Cartridge filter for a Grizzly 1.5HP Collector.

I have tried to search for the answer on this forum and I am no good good at it. I have read where Stick said that you don't need to go to fine on microns because the dust build up will help with filtering. The bag I have now it now is a 2.5 micron bag and I think that is pretty good. What I would like to accomplish with a cartridge filter is to move more air or get more performance. I can't go to a bigger collector because I don't have 220 current in my shop.

Measure once cut twice and it's still to short.

Don I think the only way to increase the flow through and decrease the micron size at the same time is to increase the filter area. That's why the paper filters you see are a pleated design. The pleating increases the surface area to around 300% of what a flat design would be.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Chuck I saw a Wynn filter on the internet but isn't there another company that make them for wood workers? Maybe I am wrong. I thought there was a lot of threads on this subject but I sure can't find them. Like I said I have a hard time finding stuff like that.

Wynn does make filters for wood workers.... Go to their website to see...
Mine listed the brands it fit .... Pick one for your collector, and they will
include the fasteners needed for your system....

I have always used Wynn filter, and most of the DC manufacturers use them too.I remember way back before cartridge filters and only bags, never heard of cartridge filters. Then Bill Pentz worked with Wynn who was making cartridge filters for big engines to make a DC filter.
Clean air standards in my life time were what actually spurred air filtration in industry.

Don, that DC looks to be the same as the Harbor Freight (HF) and the Rikon. I suspect HF, Rikon, and Grizzly all source most of the parts from the same company. There are known differences, such as HF uses a smaller impeller than Rikon. I don't know what impeller Grizzly uses. Anyway, Wynn does make filters for the HF, which should also fit the Grizzly. I went with the 35BA222NANO, but there are slightly cheaper options.

Rob did you get a noticeable increase in performance after installing the Wynn filter?

No change in performance, which is a good thing. And I'm generally a glass-half-empty kind of guy Because the Wynn is filtering down to a much smaller size (0.05 micron vs. HF's 5 micron bag), everything else being equal (such as filter surface area), you'd expect performance to go down. But I couldn't measure any difference. The Wynn is great and as Chuck indicated, the extra surface area of the filter is likely the reason.

The only thing I've noticed recently is that it's difficult to get the filter to sit on the collector, without any gaps. Some weather stripping might help, but I just haven't bothered, yet. There's no point in filtering to 0.05 microns if there's gaps.

I guess my thinking is way off as usual. I was thinking with more filtering surface I would get better suction. I guess not. My bag that came with the collector filters down to 2.5 microns and as I understand it the dust cake that lines the bag filters it more. I may be wrong about that to.

I remember Stick's post. He was saying that a coarser filter soon fills with a lot of sawdust and acts to allow ever smaller particles through. However, I went with the Wynn 1 micron since my lungs have zero tolerance these days for sawdust.

There more recently was a long string that included swapping out the smaller HF impeller with a Grizzly impeller, which greatly increased air flow, but took a long time to wind down. @Furbo didn't you guys spend a lot time working out air flow? I got two HF units (shop and garage), and am thinking of adding the Wynn finter to the second unit. It will be the 1 micron Wynn.

The more I do, the less I accomplish.
