I’m building a 2-stage setup with a HF dust collector and a super dust deputy. I’m trying to find a 90-degree adapter I can fit over the 5” plastic exhaust on the HF unit (see image). Any ideas?

I don’t know if you’re going to find something off the self to do this. You could use metal and cut, bend and either weld, screw or pop rivet it together.

One way is to get a 5” hose, Put a bend in it, and cut off the excess length. Some of the black hoses and adapters can be formed and shaped with heat (stretched or shrunk). Some plastics, you could take a 6” elbow, cut a seem in it, with heat form it to your 5” size, use heat to melt (like welding) the seem back together. If you have the patience for it.

Hmm. There has to be a fitting that works for this. Was hoping a HVAC 90 might fit?

Well, there probably won’t be (as mentioned above) something that’s plug and play. But get a 5” HVAC and do whatever it takes to get it to fit correctly. then orient it to the direction you need and tape all the sames with foil tape. You may have to slit the ends and squeeze it down, or put on some duct tape, or some similar trick…or it might fit properly right from the getgo. Another alternative (maybe) would be to get a 5” “starter collar”, cut a piece of square plywood to mount to the DC, and cut a hole for the collar. Just takes some noodling to find what you need.

2 ideas, both work very well:

1) Contact any local HVAC sheet metal fabrication shop, provide exact dimensions of square flange, round exit OD, and length/direction; they will custom make what you need.
Type ‘HVAC sheet metal near me’ into google maps for list of candidates to call.

2) Contact someone like Spiral mfg or NorFab, who specializes in DC duct work, and have them custom make a part to fit.

Best Luck.

Like absolutely everything else involving dust collection, there’s no easy, off-the-shelf solution.

If you can’t tell, I’m pretty bitter about this :)

Haha, sheet metal is just a different set of tools if you are mechanically inclined?

If you have spare $100 for hand tools or extra $1000 for shear, brake, nip/slip roller, end crimper; and room for sheets of steel; you can make all your own sheet metal duct work at home.
Grizzly sells some reasonably priced tools, including some 3in1 combo machines to reduce floor space.

Not sure I understand the issue. You are going to leave the black piece we see in the photo connected to the blower, right? It has a 5” diameter fitting, right?
If so then you need a 5” elbow to mate with the exhaust side of the blower, right?

Like this?

If so, I used a adjustable 5” elbow I got from my hardware store used for exhaust pipe on gas fired equipment. I think I paid $5 for it. I needed it to be adjustable because I had part of the garage door hardware to contend with.
You’ll have to tape all the seams when you install it because it leaks like a sieve. :)

I hope this is helpful.

Yup, exactly this! My install location is even the same, right by the garage door. I plan on trying to point the exhaust out the door or running it out with a 5” hose instead of using an expensive filter. I’ll see if I can find a similar adapter at the orange box!

Good. Glad it was helpful. You might also check with Oneida. https://www.oneida-air.com/ductwork/standard-ducting/long-radius-adjustable-dust-collection-elbows
They have a bunch of 5” fittings. I think I used 2 of those adjustable elbows to get the funky angles I needed. :)
I ran mine out a dryer vent to the outside of the garage. I don’t see any dust on the bushes so I think the SDD is doing a good job collecting it all.
I couldn’t find a 5” dryer vent so I got a 5” to 6” adapter and used 6” HVAC duct-work to a 6” dryer vent. I got it at Lowe’s.
I have a project listed on this site on how I did all of this if you need it. http://lumberjocks.com/projects/388617
Good luck. I hope it all goes well for you.
Please post your progress so we can check it out!

Check your local HVAC supplier. They will probably carry the 5” pipes and fittings and will be much cheaper than the Big Box stores. That’s how I got all of my 5” duct work and was far cheaper than the PVC counterpart.

I recently converted my 3HP Grizzly dual filter/bag floor mounted dust collector to a SSD XL with blower on top. Had to go to a HVAC shop for them to make the 5.5” x 4.5” rectangle to a 6” round adaptor for $25, and then 6” duct to my 2 wynn filters.

I’m currently doing the same, but I think I’m using wood, drain grates and pvc to make the connectors. I’d like to see your setup if possible
