- LPHV Dust extractors are overrated for small shop dust collection but I will show you how to make your HPLV shop vac perform just as well as a dust extractor.

Camvac is what they use in the EU and they use multiple vacuum motors in one unit, similar to what you built. I wish they where sold in the states.
My thinking on this subject is: I used a shop vac for years, but it was not adequate for my jointer, planner, nor my cabinet saw. The noise was unbearable. So, if I am getting the big dust collector to manage my major machines, why not use it for the smaller ones. Increasing the size of port when I can. The noise is so much more tolerable and power consumption is not that much different. I also have a small shop but I made room because I was tired of building one day then cleaning for two days.
Another huge downside to the large dust collector shown here, which is needed for larger bandsaws/planers etc is the cloth filter bags. They are useless, they get clogged easily, and often only filtering 5 microns or higher which is poor and no good for the harmful fine dust. The result is fine dust in the air settling on everything, being breathed in too, especially in a small shop. So then you have to factor in an upgraded filter, or a more expensive extractor, or one of those former options, plus an air filter which is more money. You will then need an expensive M rated shop vac for the smaller tools (mitre saw, router, sander etc). Its incredibly expensive and restrictive for something that is so important for a nicer working environment and your health.
The Reason Shop Vacs are sold it to sell more filters. A Prefilter is absolutely needed if you use a Shopvac.
That's a decent option but the negatives I see are noise and the shop vacs are going to get their filters clogged pretty quickly without a cyclonic collector that the dust needs to pass through first.
I believe the bigger one is to suck the shit out of the air to have cleaner work environment, not to hook to tools hence dust collection, and dust extractor!!!
Test parameters seem irrelevant to how we use the vacuum source connected to woodworking tools, My dual shop vac's are significantly better when hooked to my tools (Table Saw)using 2.5" flex lines than what a single vac is. I run dual Ridgid 5hp 4 gal. (The Small $99 ones) in parallel into a DustRite Y adapter and then the 2.5" hose to the tools. Building a new setup now to DIY replicate what the Canvac's do...
I think you should have a disclaimer as I'm rather certain running shop vac's in series will overspeed one of the motors and burn it out. I think you should look at Record Power dust extractor that is far better than dual vacs being that it's a smaller footprint and probably more power as well - I have a triple motor four horsepower model and I think it will exceed your dual shop vac setup easily on smaller hose, it can also use the larger hose 4" as well.
I use a single leaf blower vacuum. Works great. Two would be amazing.
duel vacs...too many DIY tools
“Ribbed for her pleasure” is wild😂
I think you should have tested the two shop vacs with a 4 inch hose to compare it to the Dust Extractor. You could get the best of both worlds. One shop vac for tools that use smaller hoses but yet you could turn them both on when you are using larger tools that can use a 4 inch hose.
A good test of theory, but I'd like to see it performed on shop tools in use.
I was using a ridgid 6hp NXT shop vac with the dustopper & 5 gallon bucket for years on my dewalt 7491 table saw and miter saw. I then got a bench top jointer and it worked sort of ok, but would occasionally get some chips fly out from the cutter head. I also got the larger larger dewalt planer (735) and my shop vac was not enough. I even upgraded to the dustopper pro which has a rubber gasket and chips were flying from the connection points on the hose. I upgraded to a cabinet saw and had to upgrade to a proper dust collector. I got a grizzly 1.5hp wall hanging model that is basically identical to the large rockler, and use it with the dust right cyclone separator and it is perfect! It’s quieter, just like you said, more of a low hummmm, and the cabinet of the table saw doesn’t really accumulate any dust.
I have both in my shop which is half of a 2 car garage. It depends on the port size of the tool. Eg. Planer =HVLP, Mitre saw = LVHP.
Shop vac for sure! I had my shop vac hooked up to a scroll saw dust exhaust and there was so much pressure I couldn't move the work piece, I had to drill some relief holes so I could move the work piece and it was really efficient after that! I agree with what you're saying!
Never considered a dual vac, very interesting idea.
The other advantage to parallel is when you use series the second motor is getting all hot air and will wear out and overheat quickly.
Restricting airflow on the dust collector is just wrong.
Just because it seems like a fun idea… I haven’t seen anyone try two low pressure vacs. Have no idea how that might perform but it sounds like an amusing experiment. Maybe something like a second LP vac put into use when the reducer has to be used.
