no previous part Part 1 of Dust Collection Issues. series Part 2: Make your own big PVC "Y's" ... Cheap !! »

Last winter Steve (kizerpea) posted this home built canister filter. It caught my attention because I had a large DC system in my Canadian shop that employed a bag filter. Having just done a canister conversion on my HF DC in AZ (how’s that for acronyms), I was all ears especially the part about using truck filters. .... FREE truck filters.

It has taken me a while to get around to it but today I was at the point where that &%^$#&^# dust bag needed to be cleaned. I HATE cleaning it and I know that it doesn’t filter well enough and I know that it creates too much resistance but I had put off the switch because of the need to order filters from another country and the fact that there are no filters set up to fit my DC.

Realizing that this time was coming I had been checking around and discovered that the local truck shops were reluctant to give away used filters (because of environmental liability I think). So I had a look at new ones and bought two of the cheapest. They are cheap, incidentally because they are very popupar and high volume sellers, not because they are any lesser in quality.

Anyway. to make a long story short, Here’s what I had when I went into town to buy filters after lunch today.


And here’s what I had at four o’clock.

It was a simple matter of building a quick manifold that screwed to the wall and fit over the 8” exhaust of my DC. It has two 7” holes in the bottom and a rod bolt to cinch up the filters.

Now for the good part. When I started it up it pulled an entire garbage can full of junk out of my system.
It was sucking madly at the distant outlets that had been disappointing from the start and it was quieter into the bargain. All this and nano filter efficiency for $100 and two and a half hours of work. Unbelievable. I won’t be able to sit for a week from all the kicking I’ve been giving myself.

For the record my system is underfloor and consists of a 30’ X 8” main, 6” secondaries and shortish 4” tertiary lines, all PVC and all connected up with very smooth home made “Y’s”. The few 4” ones never worked… now they do. The planer shavings, if they were long, as from a wide board, would often jam a line unless the bag was quite clean. Now I’m thinking of tightening the bolts that hold the planer head in the planer.

What can I say. I may not have used your system Steve but thanks just the same for the kick in the butt that got me started.

Thanks for looking in

Very cool, seems like a scary amount of dust that was sitting in your system though. Seems like it might be even easier to adapt this to a HF DC. I’ll have to start looking into this.

I need to upgrade my DC and that looks like a very good idea. I like it. Thanks for sharing Paul.

Great upgrade Paul. I have a cyclone system with a single canister filter and have been wanting to build a unit that would accomodate 2 filters. I feel it would increase the suction and reduce back pressure caused by a single filter. Your design prompts me to move ahead with it. I have also been considering a “Y” connector just before the filter with blast gtes on each leg so I could vent directly outside when the weather is good and I would not mind pulling the shop air out…and then using the other leg when I would want the outside weather to stay outside.

derosa, The amazing thing is that it was working at all.

If I cleaned the bag I would have got a lot of it but this is at least twice as good.

DIYaholic, I will do a post about them. They are really interesting and quite simple to make. If you look into buying them, you won’t look long.

That’s a cool idea.

I guess you throw the filter once they clog?

My feeling is they may clog faster; they are getting more concentrated stream of dust but I also think the cyclone brings that down quite a bit.

I am nobody in filtration, but l read a little after your post because it got me excited.
I am concern about the specific micron rating or lack of. It looks like trucks/car filter don’t have a specific micron rating.
If I understood well They are rated on a scale based on iso 5011 publication, similar to:

These are Donaldson filters, like Steve’s except a different shape. They are rated, Just like the Wynn ones at merv 15 @ 99.9% and use nano fiber technology. They are essentially the same filter as the ones sold for dc’s.
The one I have in AZ. (Wynn) cleans easily with compressed air.

Paul what is the HP on your motor? Since pipes are under floor have you had any mechanical problems?

It’s a Craftex 3Hp model. One of the many Chinese models that get painted different colors and marketed under different names. The model # is CT046, no longer available.

I have never had trouble with my piping mechanically but as mentioned above, whenever the filter started getting dirty the lines were not being fully evacuated. I think that has been remedied.
