Hello all, I’ve been a long time lurker, this will be my first post.

I bought a HF dust collector a while back, and am working on modding it to meet my wants/needs. I am working out of a 2 car attached garage (read 1.5 car), so dust control is important. I dont want to exhaust outside, because I heat the garage at times in the winter. This garage is also shared with my wife’s car, so floor space is at a premium,like most of us. So, I decided to think up….

Here is where the DC currently resides, which could change once I finish my mods. Yes, I know its a mess. I also need to find a place for the two top tool boxes resting on my table saw.

I plan on adding a Wynn filter, and a super dust deputy. I could possibly get a SDD XL to allow for future upgrades. I have been inspired by three different posts by John Heisz HERE and another design by Ty Moser HERE as well as this sweet setup by LJer WhyMe HERE

I am currently torn between two setup designs, the second and third links above, and this one, which is a modified version of John Heisz. Please forgive my crappy paint skills.

The blower will sit on top like Johns,and the filter will be enclosed in a plywood box. SDD will go straight into the filter above, and use either a drum or bin below. This plan would take up the least amount of floor space. My concern is that this design will effect the performance of the blower, however it will allow me to upgrade the blower in the future,possibly with a home made blower.

What does the LJ community think?

So including the cost of the HF dust collector, the Wynn filter, the Dust Deputy, and the shipping of all that, what would you have invested in all of it ?

$177 for the filter, $170 for SDD, $15 or so for a plastic barrel. HF Dust Collector was on sale for about $170, so $532 plus piping/fittings and I have a pretty good DC. For example, the cheapest cyclone model from grizzly is $850.

I have also toyed with the option of building my own cyclone, still a possibility.

You are thinking backwards on the filter, or your paint skills are beyond confusing. Let me explain…

The point behind a cyclone like the Dust Deputy, is in the first place, to get as much dust and debris to drop out of the air stream before it hits the filter, to increase the time between filter clogs.

I am currently running a Thien side inlet separator on a 55 gallon drum, and am getting ready to change it up to save space myself, utilizing just a Thien baffle inside the DC itself. The bag will fill quickly, but the filter will stay clean, and I can buy back the space the 55 gallon drum sucks up.

I have less money into a Delta that I bought new, and needed to do and spend very little to accomplish what your trying to do.

I am actually going a route that isn’t traditional with the order of my filter/blower. If you take a look at John Heisz’s DC build, he made a sealed enclosure for his filter media in the form of a plywood box, I am going with the same idea. The brown box around the filter was supposed to illustrate that, but I guess my kindergarten skills with paint didn’t help much.

I’m still about $300 cheaper than an off the shelf cyclone unit.

Yeah, it’s cheaper built and over rated too. It wouldn’t surprise me if they are still using a plastic impeller. And then your going to put a bunch of labor into it. And who’s to say how long that the motor will last in that position. You get what you pay for.

I guess my question is whether the 2HP HFT blower is strong enough to suck air through the filter? Just wondering if it makes a differences whether it pushes or pulls the air through the filter.

Yeah, I understand what you’re building. Shop vacs work the same way in terms of having the filter on the suction side of the impeller so I don’t think it makes a difference as long as the filter sees a delta P then air will go through it the same. What John built with the enclosure, the filter, and the blower is conceptually a super-sized, high air flow, low pressure shop vac.
