Thread: Cleaning pleated filters

I've always wondered how the big ticket vacs compared to the cheapie ones most of us can afford.

Thanks

I paid over $1800 for that unit Pete and yes I did blow the filter with compressed air out from the inside, but that kind of defeats the purpose of the appliance when you get covered in the stuff you are trying to contain.

At the time I agonised over the cost for ages as it IS a great expense, especially for a small time operator like me.

So our work sometimes involves not only sanding raw timber but also some prepainted or varnished materials, hence the reasoning behind this kind of extractor.
If I had my time over again, it would have been something like a Starmix 'M' class with the washable P.E.T. filters and saved probably $700.00.

I will try and get some pictures posted, but it is a Nilfisk IVB3H and thanks for your interest as well-Scott.

Yep great idea!-It would definitely save the filter within the main vac. Thinking further outside the box here, a liner could be placed inside the Cyclone to zip tie off rather than tipping out the contents and being exposed . What a great Forum! C.R.

Thanks for your answer on the model and price of the Nilfisk. I searched for them and found a dealer locally although the cost is a heart stopper. In my search though I found 2 Aussie sellers that have a filter for $190 and $211. Is it the same one you need$ A lot easier to swallow than the $500 you were quoted. Or is the cost including the DOP test mentioned by the first company below?

About a liner in a cyclone. The cyclone will be under negative pressure because it is before the vacuum any liner, presumed to be in the collection barrel below, will collapse from the suction. You would need to hold it open with some kind of wire cage, that would need to be pulled out of the bag before tying it closed.

To do that the wire cage would have to be placed over the liner, then to recover the liner the sawdust would have to be removed from the bag which kind of defeats the purpose of using a liner.

Isn't that what I sort of said? No worries if my Canuck needs translating to Aussie.

Yeah you did .

Oneida use a vacuum bleed line that creates suction on the outside of the bag, between the bag and the container, to prevent the bag being sucked up into the cyclone.

As do Hare & Forbes locally on this model cyclone:

Okay, so I have some new bags and a 'H' filter coming from Vacuum Doctor(cheers Pete!).

The extra premium comes in for Certification which the official suppliers like to push for-Money for Jam I guess.
Having said that, I will have a go at washing out the original clogged filter and see if it functions okay. The in built alarm will tell me, one way or another.

Thanks all for your input and sorry Acolyte if I stole some airtime!-C.R.

Cleaning filters, you can reverse blow them with a air gun. But, respirator up first because it is a real dirty & time consuming job. One reason why I don't use them. I learned that he I was using a sand blaster with a reclaimng tower. Which is a huge pleated filter tower. For woodworking I use a bag style vacuum. And, the vacuum is in a outside bag house, separate from shop.
