For starts I created a monumental mess for myself by not cleaning my Wynn filter as often as I should have. That being said what do those of you who have such a filter clean them and how often.
I finally got mine reasonably clean and I am pleased with it…..I guess. The true test will be after I install it on my dust collector. Before cleaning I would guess that my efficiency dropped by probably 50%.
I might add that my filter does not have the paddle system that some do.
Also, how long do you let yours go before cleaning.

I have a small cheap 1 hp HF bag type dust collector that I use to suck air through the cartridge in reverse. You could also use a shop vacuum if that’s what you have handy.
While I have the suction going I blow air through the cartridge from the outside using an air compressor with a blow off nozzle attachment.
This is how I have to do this now that I live in town with neighbors.
Back when I lived on a farm out in the county, with the nearest neighbor a 1/2 mile away, I just blew the thing clean outside and let the dust go where it would.

Great idea. I did do the blowing of air through the outside and vacuum on the inside but not both at the same time. Next time I’ll try that.

Charlie, I “pat” the outside of mine at the end of a shop day to knock off a lot of the dust, and then blow it off from the outside in with an air compressor at the end of a project. I have not had mine that long and I am hoping this is enough. I guess after a couple of months it would be wise to vacuum off the inside also.

When you say suck air through in reverse I am assuming that you do this by hooking the small 1HP dust collector to one of the hose outlets on the main dust collection system. Is that right?

I have not cleaned my filter yet so I am just trying to figure out what you mean.

When you own an Oneida and a drum sander you get to perfect your cleaning routine; the DC lets all the fine dust get to the filter. Anyway, I had to clean mine usually twice per drum of debris if I’m using the DS a lot. What I did was a multi step process. First, with the filter on the DC, gently slap the sides of it to knock the loose dust cake into whatever is under it. Then blow it out from the outside with your air hose (be careful, you can damage the media). Give it a few minutes to let the dust settle, and then dismount it. Take it to a hard surface, preferably outside, and lay it down. Pick each end up from the pavement about 12” (+/-) and drop it. This jars more dust out the pleats. You need to rotate the filter and repeat this about 5-6 times. Then stand it upright and let this fall out. Take it back inside and put the brush on your shop vac and carefully vacuum the inside of the filter, rubbing the pleats with the brush. The Oneida filters could be then washed out with water if needed (I’m told), something I never did and I’ve since replaced mine with an after market that cannot be washed…so after the vac the filter gets re installed.

I have a Penn State dust collector, they recommend a re-circulation line from the bottom of the filter back to the collector inlet to catch the dust when cleaning using a air compressor or a shop vac to blow air back threw the filter in reverse. I took this one more step. I separated my filters, added blast gates at the top. I can now close off the top gate on one filter, open the bottom gate on the same filter and reverse the air flow threw the filter. I do this to each filter at the end of each day of wood working. Takes about 5 mins. While I am in cleaning mode I gently tape the sides of the filter being cleaned to help break lose and dust. The cyclone will remove 98-99 % of the dust leaving the filters cleaner. I keep a inclined manometer connected to my filters all the time so I can see if I am getting any buildup and may need to cleaned before the end of the day. Reversing the filter often is keeping the filter pressure the same as it was when I purchased the collector 6 months ago.

I have added a picture and a drawing showing my modification.

John, that’s a great idea.
You could add one more cartridge and replace the blast gates with motorized dampers so that one cartridge is always able to be off line and cleaning while the other two are working.
I designed a collector a few years ago that had the interior of a single cartridge divided into three pie shaped sections. I had a rotating disks at the top and bottom with openings to block the flow to one chamber at a time and used compressed air pulses from the outside to knock the dust free to which ever section was cleaning. It was a fully automatic self cleaning dust collector.

All great ideas. These are about what I ended up doing. I think, for me, the main key will be don’t let the thng go so long between cleaning. Thanks for your input guys.

I reworked my filter system a little over a year ago and added a second filter and a cleanout at the bottom of each one. When I clean them out I hook my shop vac to the bottom and use compressed air on the outside of the filters. Keeps them very clean. I like John’s idea and it is food for thought for an addition.
