Feedback on Harvey G700 owners

New here, but highly interested in the G700 so I've followed the thread.  I ended up buying one, has not yet arrived (as of 12/8/2020).  Sometimes you'll never know until you buy and try.

* For those that wanted to see the fan curve, they have posted athttps://www.harveywoodworking.com/products/gyro-air-g700-dust-processor.  Scroll down to the specs section.  What I don't understand is they state max air flow at 1,110 CFM, but their fan curve only goes up to 750 CFM.

* I had the Oneida V2000.  2HP V2000 vs 2HP G700, I'll be curious to see if I can perceive a difference in performance, too bad I won't have both at the same time.  I anticipate them being very similar, regardless of the advertised specs. 

Since these machines are really only capable of one machine at a time, I like the G700 for it's mobility and form factor.  That was a big reason for the switch, I never did fully duct my V2000 and it's not mobile in any way.  Cycling on and off frequently isn't as much of a concern for the G700 since it ramps the motor up slowly with VFD, though, that could be an annoying wait for some.  Same with inlet port location, what's a preference for some, is a disadvantage for a different setup. Time will tell once I actually have it and use it, or don't use it for that matter.

* I don't understand the crazy price fluctuations for the G700 the last few weeks but I did have success calling in and asking if they would honor a previous sale price.  The challenge, is getting them to call or email you back.  I did get Oneida on the phone more promptly, but I can't say I've had much help from them other than "which one do you want to buy..."  I'm sure if I was spending a lot more, they would be more apt to really dig in and help.  I was considering the Supercell, their hybrid between dust collector and shop vac.

* The V2000 did meet my expectations on noise level, though actual db levels in my basement shop were higher than stated even with the  silencer accessory you install right after the plenum and before the filter.  I was around 76-78db with silencer about 15ft away.  Unfinished, 8ft basement ceilings, concrete walls.  While higher db levels than advertised the pitch and noise was never annoying (by itself).  Obviously, the tool you are running may be what's too loud.  I could leave it on (as you aren't supposed to cycle these things on and off frequently) while I paused work and them came back to my table saw.  I fully expect the G700 to be a bit louder than advertised at full speed.  I have no dissolution that their advertised numbers weren't done in some perfect environment to eek out the best ratings.

 
I’m looking at one of these as a replacement to my current Grizzly 3HP DC.  (Very loud and hope the air quality can be improved.)

I’m holding out for another sales discount to push this over the line. I’ve registered with Harvey website so hopefully they send a discount code soonish...
 
I made the decision to buy a G700 and it arrived this Thursday (12/10/2020), intact. I'm really looking forward to having this system as the dust collection centerpiece in my new workshop. Up to now I've been using a combination of a shop vacuum and several Festool vacuums. This has gotten me by while I'm setting up shop, but is less than ideal when the shop is up and running. I'll still use Festool dust collectors for sawing and sanding because they have low volumes of sawdust, but a table saw, joiner, and planer need more capacity.

I watched Next Level Carpentry for his method of unpacking and removing from the shipping pallet. I made a few modifications/simplifications to his method. Basically put two 2x6 boards on the scaffolding with one eye bolt in the center of each bolt. Then lifted each end with a hand winch, the first end was secured with a piece of 1/8 inch aircraft cable with a loop on each end. My rigging was definitely lighter weight than Next Level Carpentry, but I didn't encounter any problems.

For those wondering about the fan curve listed for the G700 athttps://www.harveywoodworking.com/products/gyro-air-g700-dust-processor, it's based on 4" duct, which explains why it only reads to 750 CFM.  That was relayed directly to me by Harvey Tech Support.  The "max" specs are just based on fan speed at the blower, no duct work.  Tech support mentioned they have been getting questions on that.  As with any specs, providing context goes a long way to help us understand what we are reading.

From my understanding to get more performance than that out of 4" duct, your HP requirements increase exponentially.  Spec wise, that appears to be on par with advertised specs from comparable Oneida cyclones.

I've had my G700 for 1 day, used it on my router table, table saw and just some general dust pick up to see it work.  I have perceived a noticeable improvement over my 2HP Oneida V2000.  It picks up the dust from further way at the hose end than my V2000 by an inch or so.  Also seems to pull harder when I place my hand over the 4" hose end.  That was expected since their static pressure specs are higher than the Oneida V2000.  This is all subjective I realize, and they certainly are generally equivalent.

I've always found it interesting when using an anemometer flush or 1" from hose end.  Put it flush you'll read significantly higher air flow than if you hold it out just by 1".  Could be as much as 50-70% more ft/minute.  Directing dust or having your hose end as close to source is critical.

G700 initial thoughts
* Unloading from pallet is doable for 1 person, and once it's off, it's ready to plug in and go.  The handle install is really optional.

* Mobile yes, but sure wish they made all the casters 360 swivel.  That would make it easier to push in any direction.

* because everything goes thought the fan blade, smallish cut offs make a large ding, doesn't sound good.
  * compared to the Oneida cyclones, large chunks never make it to the fan blade, they just swirl around awhile until they fall... sometimes never until you turn off the motor.

* Noise level quite good.  Keep in mind, my db reader was 84db, no duct work, 10ft away in a 2. car garage size shop.  A huge part of that is from the air rushing in at the 6" inlet.  Noticeably quieter once you add about 15 ft of duct connected to my table saw, without the saw running.  I believe if I eliminated air rushing noise and read db level with inlet ducted to the outside I would be right on the advertised numbers.

* running on medium speed is certainly workable as well, though, the only reason I would do that is if I want a little noise reduction and chip collection still performs well.
 
A question for Gyro Air G700 owners;

I do a lot of hand planing and chisel work in my shop. Do you think the G700 would have issues if I used it to floor sweep this detritus? I understand that the shavings will pass through the impeller, not like a typical vertical cyclone dust collector which would fall to the bin.

Many thanks.
 
Nothing to stop you, but a few things to keep in mind.

* Suction with 4" hose is pretty good, so yes it will work well.
    * I have picked up the Rockler Dust Right Bench Nozzle to pick up loose sawdust and shavings on the floor, but not for general pickup, playing it safe to only pickup wood dust, plastic stuff and wood shavings
    * Even with the supplied 6" to two 4" ports and one of the 4" ports has a rubber reducer to 2.5" (approx) that get's decent suction at shorter lengths, though I would stay with a 4" host to pick up planer and chisel shavings.

* The 6" inlet has a grid to ensure nothing too large gets to the fan
    * A lot of large, thin shavings if wrapped around that filter/grid could cause a clog more easily
    * I didn't think about this when I replaced my V2000 cyclone with my G700, I do believe that's a plus for cyclone separators, less stuff contacts the fan blade.  I even believe my V2000 supposedly had anti spark properties
    * If it became an issue, you could remove part of the grid, or all of it, though I would be reluctant to do so.

* Try not to pick up metal objects that might cause a spark.
    * I asked Harvey Support about using as general vacuum and while it wasn't a direct "no, don't do it" you have to be cautious. There are some cases where picking up metal stuff is ok, they actually advertise this for some metal scenarios.  "It depends" was their general response and it depends on the type of metal/alloy you are sweeping up.  They did say it's definitely a no go if you want to pick up dissimilar metals.  All these specifics on what it can and cannot safely pick up is beyond my full understanding, that's for sure.

Thank you for starting this thread.  I too am contemplating the G700 at this price, now.  Can anyone tell me if I don’t consider noise as a factor, am I better off to spend a couple hundred more and go with the Oneida V System 3000, 3hp cyclone?  In currently have a 2hp Grizzly and the performance with an aftermarket Wynn Hepa filter isn’t good enough for me and wondering if 2hp on the G700 won’t be that much of improvement.  I also need enough airflow for a 15” stationary planer, 8” jointer, and 3hp Sawstop PCS.

The other thing I am suspicious of is Harvey won’t address my question when I asked for a fan curve and how they based there CFM measurements.  The responses/communication from Harvey has been only from China and their US office won’t answer the phone or respond to emails...

I am looking at the Harvey and or the Oneida V3000, For my newer larger woodworking tools , Laguna BX18 bandsaw Dual 4 in dust port, Sawstop 3hp PCS with overhead 2.5 dust collection and 4 in lower with future router table insert at 4 in. 15in Powermatic planer HHC 4in port, Powermatic 8 in parallelogram jointer with 4in, Powermatic DP with woodpeckers table 2.5 in port, Shopfox w1702 shaper with 4in port, Incra LS wonder router table with 4in and 2.5 in  top port, Older Craftsman 12in disk and 6x 48 belt sander I have the Festool CT48 with dust cyclone systainer for all the small tools , ie tracksaw, kreg foreman , hand sanders, scroll saw, jigsaw etc. I am curious if the Harvey unit can handle more than one  large woodworking tool in use at one time as in the future if the boss aka the wife agrees to a CNC. I sold my 2 stage and do not have dust collection as of yet so I am off line until I buy a unit being on the fence suxs over this important and healthwise decision. Any input is welcome for both the Harvey and or the Oneida V3000 3hp 220vac 1P

As the quoted post included with my Post I have as of yet to get a response from Harvey regarding my questions California Representative. I have seen several videos on line regarding the Harvey G700,  but I am sceptical as if those are donated to the user for marketing purposes or actual consumers whom spent their own cold hard cash.  I have also spoken to Oneida and have had Mark with Oneida call me back several times asking if I was ready to purchase or if I had any questions about any of the products listed on their webpage. Plus Oneida will do a layout for me and provide the sheet metal for additional cost.  So I am stuck on the fence and need a push from those that have Harvey or Oneida units to enlighten me please. BTW I am a disabled Veteran missing part of my right lung so dust collection is extremely important to me. Thanks all for your time in reading my lengthy post.     

BTW link to Harvey listing current price at 2290.00 https://www.harveywoodworking.com/products/gyro-air-g700-dust-processor
link to Oneida current price of 2499.00   https://www.oneida-air.com/dust-col...system-3000-hepa-cyclone-dust-collector-v2019
 
Nothing against imported machinery (I have had my own share of it), but for your health requirements as well as desire for responsive customer service, I'd recommend going with a North American merchant. The price difference of 10% or so is immaterial.
 
[member=73599]jwar[/member] - my nephew purchased the G700 to work with his Minimax slider and combo machine.  He's very happy with the G700.  He did NOT plumb into a central system, only using it with a 6" hose from the tool ports to the machine.
 
Does the G700 come stock with 0.3 micron filters?

Looking at their page, it shows "commonly purchased together" items being extra bags, and 0.3 micron filters. I get ordering extra bags (though I've read that they can be reused for quite a while)... but I guess I'm not clear on whether the unit comes with 0.3 micron filters, or if they have to be added separately?

It DOES come with the Merv 17 (.3 micron) filters, 2 of them. Mine also came with an extra set of bags.  Though I ordered an additional set on top of that.  I'll reused until they fall part and then just have my extras as backups.

It's not listed on their site (wish it was) but you can purchase extra remotes.  I think I paid $20'ish for an extra remote, got 3 of them.  That's my simple solution to automatically turn on the unit at each tool, each tool get's a remote attached to it by the tool's  power button.

They only list the remote with receiver for $199 and that's for G700 who purchase their units a couple years ago when it didn't come with the remote option.

 
[member=73599]jwar[/member] Having had both a V2000 (just 1 HP less than the V3000) and now the G700 I think they are both great units and very similar in performance.  I think either could handle 2 machines at once though you are at the limits. It really depends on the needs of the two machines.  I wouldn't recommend it. 

If you are ultra concerned about dust, the stuff you don't see of which may not be picking up with these units, some in the dust collection community wouldn't consider either of these 2 units as adequate. I'm thinking of Bill Pentz and his articles and input on the topic.  Clearvue cyclone has their CV1800LH with 5PH, optional 15" fan for only $2,200.

Between Oneida V2000/3000 and the G700 the form factor, inlet location and mobility are a huge factor in my opinion why you would pick one over the other... as well as the obvious support availability.  The Oneida cyclones V systems are not mobile in anyway.  The G700 is, though it's still sizeable to lug around easily (IMO).  The ClearView cyclones take up considerable amount of space and height if that's an issue.

My only association with both Harvey for G700 and Oneida for my V2000 is that I spent my own money on them.  I've had success and frustration at getting good and quick responses from either company.  I personally don't think Oneida (based on my own experience) is so much better, though they are easier to get a hold of but that's where my experience ends, the input/feedback/support I received was close to not getting a hold of them at all.

 
  Thank you to all that have replied. I was just informed that my Powermatic Jointer and Planer are in the store awaiting local delivery. I am  going to delay delivered until the new year as I still don't have dust collection as I sold my two stage  unit and just don't want to fire those new machines up without dust protection. I do like the portability of the Harvey unit as my shop shares it's space with my multispecies fishing boat and that boat cost more than all these tools combined. One thing I can see as a drawback is the dust port location and possible warranty support or support in the future if thing breaks down. I have been to Bill Pentz site linked herehttp://billpentz.com/woodworking/cyclone/ and this site is loaded with so much data.

  I guess my next quest once I decide is to get duct work an I was leaning towards Nordfab unless there is an equal or greater product out there. 
 
I'm looking to purchase the G700 today if possible. Anyone have any current discount codes? Even free shipping would help!

Thanks in advance!
 
I am a Gyro700 owner since December 2020.  I have the unit installed in my shop primarily to perform dust collection on my Hammer K3  tablesaw.  I also have it plumbed around my shop using PVC piping and flex hose.  I do a lot of work in ensuring minimal leakage and I am very impressed with the vacuum the unit pulls on the tools farthest from it (approximately 20 feet).  I sometimes run multiple tools off the Gyro700 (tablesaw and jointer/planar) and still find that I have good dust collection.  Overall I am very satified with the performance, quietness and design. 
 
Just wanted to express my appreciation and gratitude for all of you sharing on this topic. Depending on the ease of 220v outlet install at two spots in my pending new shop I’ll have either a Harvey or the V3000 soon.

I was all set to go with the Harvey until I saw their recommendation for 6-month filter changes, which at US$300 and the work involved (see Jason Bent’s YouTube vid), is a deal breaker for me. Seemingly that’s just them being cautious though, given the comment from [member=72656]jgt1942nc[/member], ”Stuart has been using his one unit for 7/8 years and has NOT had the need to replace the filters and feels that they will last several more years.” (That comment is GOLD, by the way, and really turned me back around to considering the Harvey). Jason Bent has also said that the 6-month changes aren’t really necessary. Again, thanks all!
 
I recently bought a G700 and I love it.  The only issue I have with the design is the filter cleanout process where you need to crawl around on hand and knees for connecting a 4" hose.  I modified mine, using elbows and a Y connector to keep me vertical doing the cleanout.

I had a 1.5 HP Jet 1100 CFM and the suction of the G700 seems much more than the extra 1/2 HP.  You can get 700 CFM 20' away using properly sealed 4" metal ducting with the G700, which will handle all of my machinery - one at a time.

You do need to figure out the best speed when running the G700 on different equipment.  On full speed, a planer can overwhelm the gyro separators, causing big chips in the second bin and too much finer dust into the filters.  You should slow down to around 50 -55 speed and the G700 will still gobble up planer chips just fine.  Your ducting configuration will determine what works best.

The G700 is much quieter than my Jet but 2.5X more expensive.  I bought it for reduced noise, better fit in my small shop and the HEPA filters.  I have no need for a 5HP and 8' tall DC, nor the room. 
 
The true aim of good dust extraction is not only to catch the big chips, that is only a secondary aim, the main aim is the fine dust that we can't see and which causes the health issues later in life.

...and some machines (table saw, router table, etc.) produce a lot of the fines that are of particular concern, as mentioned.

Planers and jointer, on the other hand, produce more big chips and shavings, and not as much in the way of fine particles.

So given the time has passed. What are the thoughts and opinions of the Harvey G700? What are your gripes, upgrades or overall thoughts? I’ve recently seen one in operation and took some photo but honestly no video does the leave of noise justice.

[member=58818]Mini Me[/member] i understand your point but I’m gonna say that these units do a pretty good job at fine dust separation. The guy literally built his entire shop from the ground up and it was damn near surgically clean. An he had some very large powermatic tools like a PM224 as an example.
