Hello all,
This is my first post here at Lumber Jocks, so go easy on me:-)

I’ll try to keep this short: I ordered a cyclone dust collector in September from Grizzly ( and it is back-ordered, of course….....Murphy’s Law.

I decided to get a cheapie in the meantime and so I bought this unit, with a separator top that goes on a 30 gallon can. If it works as well as the small 5 gallon unit from Oneida does with my shop vac, I’ll be incredibly pleased.

However….......I would very much like to replace the bag on the cheapie with a pleated filter cartridge that has a dump bag at the bottom. 30 microns is just too large for my nasal passages.

Anyone have a clue as to a reasonable pleated unit that can be retrofitted onto a 5” OD outlet?

Thanks for any insight you can offer!

Best regards,

Hi all,
In the interim I found a couple of interesting things.

One of them was in the manual for the Grizzly G1163 unit. In the accessory section they had 2 bags listed, with one being a 0.3 micron and the other being a 3.0 micron. Both way better than 30 microns, right?

The web site, however, only had both of them listed as 3.0 micron, so I called their tech support. Short story is that both those bags are 3.0 micron, but one of them is nicely rounded at the end as opposed to the other which is ‘envelope’ construction, for half the price.

The cheaper one is in the mail as we speak. Stay tuned….....

You may be familiar with it, but Bill Pentz on his cyclone pages has quite a lot that’s interesting to say about what works on cartridge filter conversions for commercial units:

He links to this page where Wynn environmental offer cartridges for conversion of various commercial units, including some by Grizzly:

I’ve not carefully checked it out lately, but as far as i remember most of the Wynn filters give around 99.99% at 0.3 micron. The larger diameter ones i think are not quite as fine, but come very close…

Hi Ondablade,
Thanks for that information! As a matter of fact I received a reply from Wynn and here’s what he said:

Thanks for your inquiry.
They are not on our site yet but we now have a flanged filter with four
mounting holes for chain or threaded rod suspension. We put a low
pressure fan on top for ambient collection so the inlet is 12 inches but
you could put a homemade donut on top, and secure a flange to the
donut.The part number of the filter is C1425 and complete with 6 inch
flange, 2 Poly bags and a clamp, your cost would be $ 191.00 plus UPS.We
do not stock 5 inch flanges.

These are MERV 15 rated with fire retardant,25 inches tall, the diameter
is about 19 inches, they weigh 12 pounds, have 180 sq. ft of filter and
clean down with compressed air better than anything on the market.

Although I can not see the products he’s talking about, I’m pretty sure he understands my situation because I sent him links that had pictures of what I was trying to accomplish.

When I get the ducting kit later today, I’ll have a better idea of how well this system works to begin with. If it’s just not enough power, I’ll deal with it until the better unit gets here. I’ve been dealing with dust masks, respirators and a Netty Pot (nasal washer) up ‘til now, so another month won’t kill me more deader….......:-)

Thanks again,
