Topic tags/keywords: question

I am on the verge of buying a cyclone dust collector to help with the fine dust issue in my shop.
I like the clear view mostly because every owner seems to be very satisfied with it and the support seems to be excellent but I can get a “ready to go ” Grizzly for far less money.
This is not my question.

My question is ‘how do you clean your filter?
Long before most of you ever heard of air filter I was already working with them , especially with Farr filters with a cyclone connected to the exhaust to suck out the dirt on very heavy mining and earth moving equipment.
I was always told that air cleaner can never be cleaned, as the fine dust stay imbedded in the filter media.
I read about several cyclone manufacturer who offer different type of system to clean their filter but none seems to be 100% satisfying as they all damage the filtering media, even blowing compress air damage the filtering media.
Many offer no solution alt all.
I have a HF dust collector with a Wynn Cartridge filter.
I never was able to clean the filter to my satisfaction.
My personal preference would be to have a smal vibrator on the filter which would run for a few minutes after the collector is turned off.

So , you cyclone owners, how do you deal with this issue?
Thank you for reading.

PS: can you tell me which cyclone you use and how you like it?

I admit I use compressed air, but at a very low PSI (around 10). I wish they made oiled filters like they do for cars. Spray the cleaning solution on, wash the element, re-oil it, done.

I have a small box at the bottom of the filters, sealed of course, I tap the sides of the filters all the way around them on the outside, then take the side cover off of the box, and clean it out. I was wondering if a chimney cleaning brush might work. if the handle was flexible enough to bend into the bottom of the filters. but I don’t know if the brush would damage the filter material.
oh yes, I do have a Clear Vue, and it works great

woodsmithshop,
Grizzly offer a similar system but I have the same question that you have.
If brushing hard enough that dislodge the dust, would we damage the media?
The brushes for chimney that I know are made of steel, so for these ones this is a definitive”no”.

I have the Wynn Environmental cartridge, as well.

At the end of every project, I dismantle the DC (this takes 15 minutes, at most); then use a small compressed air blower to blow-out the dust particles. This is a messy, but very effective solution.

Some manufacturers do provide means of cleaning filters – either manually (typically an exterior handle which moves an internal brush array; or electronically, where the internal brushes can be activated by a switch).

Clear Vue cyclones get high marks, though my understanding is they require an assembly process. The rights to Clear Vue was acquired some years ago from the original manufacturer.

My complete system is outside of the shop in it’s own little closet so it’s not a real big issue for me but when I clean the filter, I just unstrap it take it outside hang it and get the broom after it. BTW Bert I to have the same DC.

As a person who gets to do this a lot, I doubt my techniques are very enlightening. It’s a multi step process. 1st, I knock on the sides of the filter while it’s still mounted with the palm of my hand, just to knock what dust I can into the bottom canister. Then dismount it, sit it on the floor, cover the top opening with a scrap piece of wood, and blow it out from the outside. I take it off to do this because I can get around it easier, can’t quite get the back side while it’s still on the cyclone. This has the unfortunate happenstance of leaving a very large pile of very fine dust on the floor. I sweep what I can into the dust pan and throw it out (literally, into the wind). the shop vac with drywall bags gets the rest. Next, I’ll lay the filter on it’s side on the floor and lift one end and drop it, maybe 12” or so. This helps dislodge more dust in the pleats, I rotate it and do this several times. The final step is to carefully vac the inside with the shop vac and the brush, requires considerable care. It’s now as clean as I know how to get it. All this takes about 20 minutes and I almost always do it every time I empty the dust bin, one of the reasons I want to get a CV, mine just lets too much dust to the filter. All this, and it’s still not as clean as I would like; oh well!

Thanks for asking this question Bert. I have been shaking my HF OEM bag for the past three years, HOWEVER, I have just ordered one of the 35A filters from Wynn. Of the 3-types of 35A filters, I chose to purchase the “Spun Bond” media because of its 380 PSI burst strength wet or dry. Sure it is 1-micron vs 0.5-micron, but it beats the heck out of the 5-micron OEM bag. The folks at Wynn Env. also indicated a couple of things I was not aware of:
  • The Spun Bond will clean easier with compressed air—fewer pleats and larger filter holes.
  • Wynn now recommends NO washing of any filter media—folks just can’t or won’t take the time to adequately “clean” AND adequately dry the filter before re-use. A wet filter plus dust = mud. And that then becomes a permanent un-removable blockage.

My new Wynn filter has yet to arrive, so I have no personal experience regarding what the Wynn folks shared. Once I get my hands on the filter and use for a while, I’ll be better able to confirm or deny the above information ;-)

HM:

I think you’ll be happy with the Wynn Filter – mine has a lot of bdft. under its belt, and continues to work just fine.
