My shop is about 9' wide. The ducts are on one side and the bandsaw is on the other side. This is with the duct attached to the bandsaw.

If you are blowing the air outside, then choose a filter that will capture the dust, but give you as much air flow as possible, like 30 micron bags. There's no reason to filter the air you are...

Thank you, Chris. Venting a short cyclone outside is not something I had considered.

I know you advocate for a VFD, so I researched that when I was buying my ClearVue. At the time I concluded...

I believe that you guys have a lot of wisdom and I have learned a lot about dust collection from you. However, when you are in the US and Google about dust collection, this forum is rarely returned...

The fan is a FanTech FG8. There is fan curve information on that website. At zero static pressure, it is rated for 461 CFM.

I measured the air flow using a Testo 405i hot wire anemometer,...

Thanks. It draws air from outside the filter and blows it out the top. Bill Pentz said he tried both methods and this way is more effective. The standard for these industrial filters is dirty air...

I built an air cleaner and seems to work great.

My last post I said I needed advice and then posted it in the middle of the night in Australia and didn't even ask a question. Oh well.

Today I took out muffler 2.0 and put in muffler 3.0.
...

I need some advice.

As you can read previously in this thread, I originally had a muffler made from R8, 10" flexible HVAC duct that looked like this:

My measurements at the exhaust,...

I know a guy who built a Pentz cyclone and vents it out a window. The partially open window has a board with an exhaust hole. The exhaust from the cyclone goes to large diameter HVAC flex and then...

I have an unconventional recommendation: Start with measuring.

The hard part about collecting invisible dust is that it is invisible. I bought little meter from Aliexpress that has a Plantower...

I read warnings on here about cyclones sucking up rags, which get stuck in the impeller and then you have to disassemble the cyclone to get the rag out.

Tonight I was cleaning up the shop using a...

I'm thinking about getting or making an ambient air filter for my shop. These have different names: room air filter, air cleaner, air filtration system, air purifier

I have a ClearVue that vents...

Tonight I was cleaning off my workbench using a 4" flex hose. The remote that starts and stops the cyclone got sucked up before I even knew what was happening.

I attached a 5' length of 10" straight pipe to the exhaust to measure airflow.

The exhaust pipe is propped up with a sawhorse to minimize back pressure from air hitting the ground.

The sound control I implemented for my Clear Vue worked very well. This is a cyclone with a 6" inlet and a 16" impeller running at 60hz (single phase 240v in the US).

The cyclone is in its own...

I'm not sure if the fact that hasn't happened means there is a leak or if this trash can is slightly stronger. Also, my empty can did not lift off the ground like I have heard some describe.

Right now I have a very short piece of 10" duct just shooting straight out the back of the building horizontally. I was planning to build a wooden box around it, kind of like a wooden dryer vent.
...

I got two requests for more photos.

This is a better shot of the link between the dust collector shed and my shop. I sealed the hole with something that's like industrial Silly Putty.

I have made some progress. As a reminder, I'm installing a Clear Vue Cyclone in a separate building dedicated for that purpose.

I made a dust collection bin.

That sounds right. The quick-clamp stuff (Nordfab and the clones) seem like the purpose-build industrial answer. That ducting is really, really expensive for a hobby shop.

I clicked on that link...

I understand. It also seems that the performance of the system is difficult to measure so many people don't know whether their system performs well or not.

BobL, what would you use to determine...

I don't understand why spiral ducting is not more optimized for air flow.

I know in Australia metal ducting is very expensive so nearly all the installations I have seen on this forum use PVC. In...

Pete, horizontally the pipes line up pretty well. Vertically, if I make both pipes level, then the one on the right is 6.25" too high (center to center of the two pipes is 6.25").

After sleeping,...

Two topics: noise and duct connection

On noise, several of the posts I have read ended with something like, "I could have just used an insulated HVAC duct and that would have been much easier." ...

Thanks for the suggestions, guys.

I live in the US, but reading this forum has helped me so much. Thank you for everyone who shares their wisdom.

I bought a ClearVue about a year ago, around the time they were discontinued in...

Neil, thank you for the great writeup. I do feel like dust collection is "too hard" and I'm hopeful that someday there will be easier answers.

One additional thing I considered is that if the...

BrettGG, if you are venting outside, don't think a cyclone is required. You could use a 3HP, 2 bag collector that has a large enough impeller (13+") . In fast, that's what BobL uses.

I am...

I'm back with a report. Right now I have a 1.5 hp bag collector with a 10" impeller. As an experiment, I tried sucking up hand plane shavings.

Small, narrow shavings from addressing an arris...

This is a very interesting observation I had never considered. Having a shorter taper also reduces the height requirement.

I bet even in the US there would be a market for a strong, short cyclone...

On the US website, they have dimensional drawings that are slightly different than the one in the manual.

Today I visited a guy who replaced the dust port on his Dewalt 735 planer with a hood that connects to a 6" hose. He said it made a significant difference in chip collection. The product he used...

My shop is less than 3m x 6m on the inside, so I am significantly more constrained. Here's my suggestions:

I saw in the news today that some people in the US are building DIY air purifiers for schools which look exactly like air purifiers I have seen in woodworking shops: DIY Air Filters For Classrooms?...

FYI, I believe these are the impeller sizes for some of the machines in that chart:

Cody, I really don't have practical advice, but I do have some observations.

Right now I don't have a power jointer, so all the initial surfacing I do by hand. This produces a lot of hand plane shavings. I put those shavings in a 30 gallon paper leaf bag. Two questions:

That all makes perfect sense. I was trying to do an exhaust fan as a interim step before a cyclone, but especially since I have so many windows and doors in the shop (see picture in first post on...

I guess one of my questions is what is a good target air exchange rate. I have seen 8" centrifugal fans marketed for hydroponics that say they move 740 CFM, which seems very unlikely. (VIVOSUN 8...

Yes, Bob, you guess it. I don't live in Burma or Liberia.
