I have a 2 HP harbor freight dust collector that I need to modify so that it’s more space efficient while at the same time helps maintain dust free emissions. I came across some plans that I would like for I follow. Please see photo for visual.

Key notes
1. The cyclone is made using sheet metal and is held in place with a wooden frame that’s anchored to the wall.

2. The filter is strapped horizontally to the ceiling. It is a cartridge type air filter that’s used normally used for diesel trucks (e.g. NAPA 6616). The filter is wrapped inside of a sheet metal housing.

Concerns
1. Is this type of small cartridge filter good enough for minimizing dust emissions? I like this design and configuration for space efficiency just not sure how well it will work

2. Time it will take to make all the parts out of sheet metal. Considering the idea of buying the super dust deputy and using it in this type of application. This way I don’t have to build a cyclone out of sheet metal. I would still use the same filter design.

Looking for some input on the design and whether or not the concerns are worth worrying about.

i just went thru installing a dc in my shop. your pic shows 6" hvac pipe first off it's very leaky, the long seam and all the joints on the segmented 90° and fittings leak like a sieve. not a problem in a heated house cuz leaks heat space. from my research pvc pipe is smooth and probably the best for your purpose. 2nd the harbor fright blower is to small for 6" pipe, the air velocity won't be enough to keep the dust/shavings in the airstream. plus the transition from 4" to 6" drops the speed of the air, similar to how the cyclone or thein baffle works. i'd recommend running all 4" pvc sewer pipe. you can't use more than one drop and have dust removal anyway. i'd also recommend not having drops come out of the bottom as any shavings from down stream can drop into the drop pipe.

as stated, i just went thru this and made my own blast gates and thein baffle. just the flex hose adapters can be quite a bit of cash at $10 each, i made mine for less than $1 each. my blast gates have proven to leak minimally and i automated the dc with switches at each blast gate. all in all i'm pretty happy with it
look thru my build for more on that woodworkingtalk.com/threads/dust-collection-ogre-style

I don't think that's his system based on the "see photo for a visual" comment he made.
The suggestions still apply however.

I think that one will clog up quickly. It's also not easy to access.Look at a canister filter, they are multiple X the size and have a built in scrubber.

Other than the 2" hose. I would eliminate all that small duct, not gonna get much out of that. Better to use a shop vac.

If I use a larger canister filter like the one in the line below can I still mount it horizontally against the ceiling joist or would that impact how it works?

This is the most famous man in the world of dust collection. Everything you are ever likely to need to know is in here somewhere.

I am a huge fan of the Bill Pentz site and I've posted it here many times.
It takes days, even weeks, and in my case years, to absorb all the information on the site and put it into practical forms.
Another great source of dust collector information is from Oneida, a manufacturing company who also uses the cyclonic separators that Bill Pentz advocates:

The issue I have with all those small cyclones is they end up stacked 6 ft or more higher and the weight of the suction hose wants to tip them over.
I experimented with internal baffles and deflectors I could locate inside my 1.5 HP Jet DC separator units that wouldn't take up any addition floor space or make the unit any taller. I couldn't tell any appreciable difference in performance after multiple attempts. The entire reason for the cyclone, unless I've missed something is to keep the fine dust out of the pleated cannister filter to eliminate constant cleaning and prolong it's life. Personally, I don't mind running the paddles every so often and blowing out the big filter outdoors with an air hose.
