Thread: Harvey G700

I haven't but out of curiosity await an objective review of it. Harvey makes two bigger ones for those with the deepest of pockets. Harvey Gyro Air Dust Processors – Harvey Tools

I have never seen anyone report a real time review on one. Spending that sort of money is a definite h(w)ealth hazard if it doesn't work and I know a Clearvue works.

Chris I read a few reviews and they were positive.Design and shape wize they would be a great space saver in my shed.If the noise levels are what they say I would be very impressed.There is a dealer down at Albion Park but I doubt that they have anything set up just a depot.

cheers.....Roy

Next Level Carpentry has a good video review, and some setup videos on YouTube. He is a user, not a vendor.


Matt Kenny did a short review in Fine Woodwoking:
Tool Review: Harvey Machinery’s Gyro Air G700 - FineWoodworking

Axminster also sell this in UK under a rebranded name, but interestingly I don't recall any reviews from the UK woodwork forums.

I'm biased, everyone knows it and so read everything I wrote with that in mind. I have suggested to Roy if he is interested enough to call BBT and see if they have sold one locally that he could see working, I for one would like to see one as well. How that bloke in the video can work with all that flexible hose laying on the floor defies imagination, certainly mine. The only real problem with the machine that stands out immediately is that anyone using a conventional straight blade thicknesser is going to be very busy emptying bins.

The performance of the machine at keeping dust levels under control has not been demonstrated yet but it would stand to reason that it must be at least partly beneficial. Noise levels are neither here not there internally in the workshop and this is no more quite than my present system and when a machine is fired up it can't be heard at all but the Harvey must get the nod on taking the exhaust to atmosphere noise away thus keeping the neighbours happy. That part is the one big disadvantage of venting to atmosphere whereas in the US 99% of DE's are self contained and do not exhaust to atmosphere due to climate reasons. This machine is aimed at that market.

Cheers Chris if I get time I will give BBT a ring as we discussed and see if they have sold any so I can chat to someone who has purchased one.
There is someone else selling them and might try and give them a bell and do the same.In the event I do buy one I will sell you the first ticket to
check it out

I saw one of these at one of the woodwork shows a couple years back when they just came out. They are quiet (as quiet as anyone could expect a dust extractor to be) - I have one of those generic 2HP dusties, and it was quieter than that by a fair margin. I vaguely recall reading on a website somewhere this thing was around 72db running, and I believe it.

At the end of the day, in most cases, when you flick on the dusty, you've got another machine making a good racket anyway, so it's not a deal maker or breaker in my book (your mileage and preference may vary, and that's fine).

What concerns me (and as I continue fitting out my new workshop, I am reading more and more in the dust extraction section here) is that this thing only has 4" ports on it - and aren't most folks "in the know" around these parts suggesting everything needs to be opened up to 6", even if it's for "weekend warrior" exposure?

Bear in mind, dollars-wise you can take a choice between the Clearvue 1800/MAX or one of these. And the Clearvue has a lot more data (and acceptance?) behind it?

The article in the Finewoodworking link above states it has a 6” port as does the video.

As stated, this and the Clearview are a “shedload” of money. I would rather spend on a good bandsaw and table saw before spending big money on one of these items. I can wear a respirator for the fine dust.

Its like having the best saddle and bridle and blanket and a 40 year old, worn out hack.

I have the opposite opinion. As much as I love my bandsaw and table saw etc I would give each up before the Clearvue. What I really don't get is when people spend nearly the price of a Clearvue more for a Sawstop vs a Harvey or similar but have a poor dust collector. Health should be a top priority IMO.

The 2HP DCs I have played with have been in the 82dBA range but this is non issue when any DC is located outside the shed or in an air tight enclosure inside the shed. This is the simplest and most effective way to deal with DC noice and handle DC dust leaks and any fine dust escaping the filter and released when emptying a DC.

DC noise is not always masked by other machines when the DC is used inside a shed as many machines, eg lathes, DPs, sanders, and bandsaws don't make anywhere near the racket that a DC makes.

However there is still another issue in that really high volume extraction at dust source even with a BMH makes plenty of a hiss and there is little getting around it.
If it's not hissing to the point of some annoyance then either you are (partially) deaf at those frequencies or your system may not be moving enough air.

At 40Hz the air going into my 6" BMH on my wood lathe emits SPLs of 75 dBA at operator ear level, at 50Hz its 80dBA, at 60 Hz its 86 dBA.
The last one is significantly more than most DCs and I can last a couple of minutes at this SPL before I need to use muffs.
I only use 60Hz when I'm doing the dustiest operations as my dust particle moniters tell me that 40Hz is enough for some operations and 50Hz easily covered almost everything else,

This noise source is even worse on smaller ducting and is one of the many reasons why 4" inlet DCs aren't readily available with 20HP motors and 20" impellers as the thing would sound like a jet engine.

As this to me is a hobby and I’m not dripping with money, I prioritise my purchases but run a risk assessment beforehand.
No dust extractor is going to remove 100% of all dust particles although some are better than others - granted.

My modified 2hp system, with through flow shed ventilation and wearing a respirator is my control.

That has been revisited and found, for the level of work I do, to be adequate. If what I do changes, I will assess the risk again and make changes as required.

Cant see the sense in paying for a Clearview if you have nothing to cut timber with

Not pushing you or anyone to buy a Clearvue mate and not trying to say what you do with regard to dust collection isn't adequate. Just saying that for me, having great dust collection is a necessity, particularly since I know i'm not good at making myself wear a respirator (and it makes woodworking less enjoyable for me), don't have good ventilation, and have developed a sensitivity to dust already. So for me, if I couldn't have the Clearvue or equivalent, there wouldn't be any point having tools as I wouldn't use them. But that's me. Everyone should make their own decision, and as long as it's an informed one, it isn't wrong.

The reason I used the Sawstop example is that this is a common scenario and clearly if one can afford a sawstop industrial or professional saw with accessories, they can afford a great dust collector, but are putting the shiny saw ahead of their health - and I find this perplexing given that most site the safety feature of the saw as a primary reason for the purchase (can you tell I have a bug in my bonnet lol).

i’m sorry But I don’t see the logic in the statement that just because I bought a Sawstop industrial I can also afford a Clearview. Why would everyone that bought a Sawstop Industrial have another $3000 to $4000 lying around?

Hi Lappa,

My logic is that the sawstop industrial costs about the price of a Clearvue more than a saw like a Harvey or Carbatec et al, and the reason often given for paying the premium, other than possibly better fit/finish is that the Sawstop is better from a safety perspective; i.e. health. In my opinion, keeping dust out of your lungs contributes far more to your health than a possible prevention of a cut. So to me it's illogical. To me. Not saying my opinion is right. Just my opinion. Also, the Sawstop is a premium product that costs far more than the price required to get that functionality. So a person that can afford that sort of tool, should also, to my mind, be able to afford a Clearvue or similar. Not saying they need to, but lack of money isn't likely to be the determining factor - they may just not value dust collection. Which, as I said, is fine if that is their informed decision. Just doesn't make sense for me.

Cheers, Dom
