Was at Woodcraft yesterday, and saw this DC / processor and it was impressive looking. Every now and then someone throws something radical out there and this is one of those times. Seeing it up close it seems real impressive. I googled it and watched some vids. Expensive, but liked the concept. Anyway if anybody else interested in DC, looks interesting. I like the DB level (advertised), but thinking after looking at spec's its designed more mobile. I could not find spec's i.e. static pressure or cfm. It does have Siemens controlers so its not appear to be crappy built.
Don't know, but is an interesting concept.
The Harvey G700 GyroAir Dust Processor at Woodcraft
This machine was just brought to my attention, too, and it does look like a skookum machine. Their claim of 1100 CFM, max, and 700 CFM through a 4" hose is interesting, as I did not think you could haul more than about 400 CFM through a 4" duct w/out massive air speed; don't quote me on that, it's just what I recall. If anyone has feedback on this unit, please advise. Thanks. john
I have read about these. They claim 18.5" static pressure which is very good, variable speed and quiet are impressive.
But at about $4000it is a little expensive.
There was ( and still is) a company that makes hydraulic devices and came up with the "Rainbow" vacuum cleaner. It was a device that used water as the filtering agent for airborne dust. It was (is) so effective it has been used for clean rooms where the tiniest spec of dust would contaminate the room. I know because I was selling them door-to-door 40 years ago. It was expensive, but it was the most powerful and totally dust free system around. Today's HEPA filters do a pretty good job, but still can't beat the Rainbow. I mention this only FYI. It would be great, but would quickly clog up with the large amounts of dust produced in a wood shop. I wonder if that company ever thought about using that technology for dust collection systems in a wood shop.
I was interested in water filtering at one point.
I found a blog where somebody with a dust
deputy pulled the dust through water in a
second 5 gallon bucket between the DD and
a shop vac. Looked like a good idea to me.
I also read about putting a drop-out box with
water in the bottom in between the blower
and a cyclone filter. I don't remember exactly.
I was interested if I could figure out a way to
avoid cleaning my cyclone filter as often.
I lust went on the net and pulled up "Rainbow vacuums" and reviews and comments. Almost all of the comments were great in regard to the performance of the machine itself, but almost all the respondents complained about pushy high pressure salesmen. That was true 40 years ago and I didn't do well then as I am not the pushy type.
My folks have a Rainbow vac they inherited from my grandparents. The switch and cord have been replaced and the hose is next on the list. Other than that, it's still working.
Regarding the dust collector, Marc Adams School has one (or did last year) so somebody that works there could probably answer questions about it.
I suspect it's designed more for trade show demonstration and office environments than actual woodshops. It's compact and looks nicer than a typical cyclone which would be a big plus in certain settings.
Funny you mention rainbow vac's. Funniest story I ever heard was rainbow vac related. I have a friend that being a good natured fellow and could laugh at himself told the story.
He was watching the kids one day while the wife was away and was not paying that good attention and while feeding the infant in the high chair, the 4 year old managed to knock over a big box of tide. He being the the guy on the ball, ran got the vac and started it up and started sucking up the big pile of tide.
Well you get the picture, with the rainbow it started spewing bubbles….a lot of bubbles. Problem was he had his back to the the unit and after sucking it all up feeling proud of himself turned around to see the room engulfed in bubbles, the kid's high chair had dissapeared.
Even funnier was him o'pining that "ya know there ain't no way to easily clean up bubbles"
To make it better the wife comes in and the kids are running around with bubbles on their head and him holding the baby.
LOL
Saw this old post, got curious,
Appears even 2.5 years after OP, the Gyro Air is listed on Woodcraft, Rockler, and Bridge City sites as direct ship from mfg, with zero feedback. Even on sale right now for $500 off.
Then I looked up Harvey Industries to learn more.
Found a bunch of export records showing Harvey customers are pretty much every wood working equipment OEM in market.
If you look over at their Alibaba product catalog listing, you will recognize the features and capabilities of table saws, bandsaws, shapers, and lathes pretty quickly.
Looks like a cool DC. But like all cool tech, if price is 2X compared to main stream units; it is hard sell.
Watching thread for fun.
I think at some point it's more cost effective to just throw a bigger DC at the problem, with more/better filters on it. This does seem like a cool device though.

I'm actually looking to do the opposite. I've had an Oneida v3000 for quite a while. Looking for something quieter and building a closet is not an option.
I have my cyclone in my lumber storage room, along with the air compressor. Much quieter than in main shop. I vent outside and that is great if you can pull it off. Twice the suction as using the filter.
I just replaced a 2HP Cyclone DC with the Gyro G700.. I am not sure what is up with the pricing at the various other dealers but you can getting it directly from Harvey for $2599. At this price, compared to my previous DC, this is a bargain. I had it set up in 30 minutes, most of that time was cutting up and throwing away the packing materials. First off the build quality is unlike any machine I have owned from Taiwan to China. I would have guessed Germany or Austria, everything is extremely well though out with the exception of 1. The location of the inlet down low, close to the floor. 2. The main cut off switch is behind the machine and not next to the main control panel. The inlet actually suits my shop as I run 6" to 2-4" ports at the machine with blast gates. Then use flexible hose with MagPort connections to each machine. I could see the bottom inlet not being ideal if you had duct work on your ceiling you needed to tie into. As far as sound , it seems about the same as my old cyclone when the G700 is at full speed. I am not sure how much I will use the variable speed, I just want my DC to suck as hard as it can with my 12" jointer, 15" planer, 10" cabinet saw and 19" bandsaw. The form factor may be an issue for some. For me, it works as now I can put in cabinets and a work area above the Gyro G700 vs. my cyclone, was too tall to put anything above it. But I think this is 6 one half dozen situation. All in all I am really surprised there is not more about this machine out there. It really is a great machine.
Looks pretty neat. 2HP, 6" port, variable speed motor. Up to 18" SP. 1,100 CFM. But then It's not at all clear what CFM at what static pressure. Looks like competition for Oneida's Dust Gorilla Pro, which has 5 HP and variable speed motors or possibly the less expensive Oneida Super Cell.. The Gryro looks pretty expensive when compared to Oneida's offerings.
Glad to see comments from someone actually using one, not all the abstract comments earlier in their thread. It seems to be their flagship product not their version of the various OEM tools they make.
Harvey footprint in the US is only a few folks in the West coast office. They are a huge OEM in China.
FWIW, water bath filters work for fine dust but can't be too high of velocity. Balancing act. They work well for drywall dust for instance.
