Hi all,
I am not a novice woodworker 20 some years working in my own shops. I still have questions. Have had several dust collection systems. Present system is a 2 HP Penn State cyclone w/6” metal piping w/drops adapted down to 4” at tool connections. Works like a champ. However about 2 times a year I can since a bit of a reduction in the suction. Not a bunch but since my friends consider me anal about dust it bothers me. I go about a cleaning of the canister filters. PITA enough said. I am looking for your tips to this process. I am getting better at it but just wondering how you do it? I now take the filters 2—14”X 30” connected together outside and beat them with a stick to loosen the dust inside. Then stand them on a 5 gal. bucket and blow thru the sides w/ a high power leaf blower. Sure does make a bunch of dust coming out the top opening. Scares me the neighbors have not complained. I use the leaf blower to blow every way I can think of like with the filters lying down and changing end for end and from inside to outside while collecting as much of the dust as I can. Today I got appx. 5 gallon from a system which seemed to working ok but it was a PITA. Any other ways or tips would be appreciated. I know some of you guys go thru this also so lets help each other. Thanks for reading and thanks for your ideas.

I use my blower to get rid of the majority of the dust, then I use my shop vac to finish the job.

I had Penn State Filters (made by Clark Filter) on my Oneida. My cleaning for them was the same as it was for the Oneida OEM. While on the DC, I would slap the sides of the filter to dislodge anything possible to fall into the catch can at the bottom. Then dismount the filter and lay it on concrete on it’s side.Lift each end about 18” and let it drop, do it on both ends, and then rotate the filter and repeat. This was to dislodge more of the debris. Then stand it up and cover the top opening with a piece of wood (or something). Use an air hose to blow out more of the debris, be careful with this….maybe regulate the pressure down to 50# or so. Lastly, take your shop vac with a brush and vacuum put the inside. My Clark filters had that woven mesh guard on the inside making this a little more difficult, but it still worked fairly well.

Just a thought. Do you really need to remove every last bit of dust? I have read that canister filters only achieve their highest dust catching efficiency after some use has built up a layer on the surface. I am not a really heavy user in my hobby oriented shop, but I just slap the sides on my Wynn canister and let the dust fall into the collection bag.

I whack it with a 2×2 on the top and sides, just like Wynn says to do. I believe that frees up the caked on stuff. As Kazooman says it falls off into the bag.

I use an electric leaf blower to clean the filter as you do, but I don’t remove the filter from the DC. I move it away from the wall enough to get to all sides. All the dust goes into the collection bag. I’m using a Super Dust Deputy in line with the DC, so the only dust in the bag is from when I clean out the filter.
