Has anyone thought about using automotive type air cleaners in place of cartridge filters in the return on a DC?

There have been several threads here, that use semi-truck air filters for their DC. I don’t have a link, but a search should work.

The problem with doing that is that in a wood shop to need to filter 0.5 micron dust,
I do not know that truck or heavy equipment will do that.
In addition these filters are not cheap.
You need HEPA or Merv 15/16 filters , they are not cheap.
The worse thing you can do to yourself is having a false sense of security using filters that do not in fact filter the fine dust.

MrRon, This is what you are looking for . You can catch these on sale at a Kenworth or Peterbilt dealer for around fifty bucks. They will work on a DC, these things filter a massive amount of air going into a $30 – $60,000.00 engine, talking near 100% filtration. Just a small amount of dust, dirt or debris is expensive. Now this comes from owning several trucks, the last rebuild I did on a engine was $20,000.00.

1 Tablespoon of dust will ruin a diesel engine. Truck and tractor filters filter in the 2 to 3 micron area. I have rebuilt a lot of engines that had filters that had a pinhole or the seal wasn’t seated properly.

Here’s the forum link to this question

If you search the LJ forums for “Donaldson” filters – you will get some info on the subject

I contemplated it – but bought a Wynn Nano anyway – happy so far – still experimenting

I used Donaldson truck filters on my DC reno and they are great. Same nano filter ratings as Wynn, just a lot cheaper.

I built this dust collector several years ago, it works great but I may go with a larger filter made for the dust collector.

I was looking into the Donaldson filters, I couldn’t find anything that listed the merv rating, micron level of the filtering, or the surface area of their various filters. Also, it seems only the blue ones are nano? Can anyone confirm this?

I looked in the past at Farr filters as I know them for many years and I work with them today.
I could not find filters filtering to 0.3microns.

I really don’t know the answer, but I have a few thoughts on it. I would like to know more.

Air flow through a truck filter is opposite of how air flows through dust collectors. On a truck the air enters the filter element from the outside and exits through the center. On a DC, the air enters the filter through the center and exits out the filter element. I really don’t know if this will be a problem, but I have my suspicion. If you use it, and like it, I’m glad for you.

DC filters usually have a means to clean the filter. Mine has a handle that connects to flaps inside the filter. Rotating the handle agitates the filter and gravity does the rest. The truth is , they don’t really work very well. If you disagree,rotate your flaps, take off your filter, take it outside and blow low pressure compressed air , from the outside in, and see what you get. You won’t get that flap with a truck filter.

All the air that gets sucked in the hose must exit through the filter.

With allowance for inflation, that’s my 2 cents worth.

Looks like truck air filters will work and are a lot cheaper than the ones sold for DC’s. The only thing that concerns me is; when used on a truck engine, the air flow is from outside the filter. In a DC application, the air flow is reversed. Will this make a difference?

I had the same question,.
I guess the material the filter is made off , really does care about the the air flow direction.
My concern is truck air cleaners not filtering the finest dust, the dust that really arm your lungs.

Thank you Dallas, notice that these are not heavy equipment or truck air cleaners.
The post is about automatic type air cleaners used on dust collectors.
I do not know how small a dust particle these filters stop

If you look at the pdf files some of them filter down to .02 microns.

Being in the trucking industry for 50+ years I can also tell you that modern air filters filter that much or more, depending on the system. Some have primary and secondary filters.

Look at page 3 of donaldsons truck filters here.
