It's my understanding that the two halves of the scroll don't touch so the parts that touch air don't need to be lubricated--so no oil in the air. Hopefully, the Eastwood rep can verify or correct that.

He says in the teardown video that oil is used to take up up the gap between the scrolls so they don't have to touch, and an oil separator is used.
I have to admit I'm interested in this. It's tough to buy something that just hit the market, especially when it has only a two year warranty. Would be nice to see a longer warranty on the pump at least.

Exactly, JonnyC.
it uses oil to make the seal, which must be kept very clean and cooled down and extracted from the compressed air. So I was wondering how effective the oil extraction system was on this unit.
My old single stage 60 gallon Campbell Hausfeld has served me very well over the years, but it only puts out 9.1 CFM at 90 PSI and makes an annoying racket. This little guy would put out more, take up less space so I could install shelves over it, is portable, and makes almost no noise.

Probably not. Why not just add or convert to a 240 volt circuit? Unless your garage has something crazy happening, it’s pretty easy.
We purchased a house with 3 floors and our bottom floor is a subfloor. So the entire house is completely finished. I really don't like the contractor since he wired the whole house for coax but didn't wire it for cat5e/6. The garage is completely finished as well and I have to break down dry wall again to fish wires to the garage. There's 2 outlets in the entire garage, well really one that you can get too. I have the furnace room right next to the garage and may be able to tap into the lines for the heat. I'll have a electrician swing by and take a look. I'm also going to ask him if I can bring in 3 phase into the garage and hope it doesn't cost a arm and a leg.

I wonder how long before harbor freight sells it? Anyone manufacturing in China to maximize profits is going to get ripped off by the Chinese, just ask snap on. I guess I will watch it happen, while listening to my 50yr old quincy 325 sing a quiet song .

You could wire outside the walls with galv pipe and boxes. I think you will find three phase prohibitively expensive. Better would be to use VFDs or a RPC if you have several machines.

Perfect, and just in time!
My last home workshop had a 5HP Quincy upright unit which is fantastic, but it had to sit in a separate shed (outhouse?) to keep the noise out of the shop.
I was about to pull the trigger on a Quincy or IR for the new shop, and see iff I could jury rig it to fit in the enclosed area under the stair landing to the storage attic... but its too tall. I've even been looking at accessory sheds to put it in.
This will fit under the landing just fine, leaving plenty of room for sound insulation and the sump pump and water heater that shares this space.

3-phase is completely different from 240V and is usually a commercial service. Expect to pay not only for the installation but for commercial electric rates.

Basically by allowing companies like Eastwood to do the R&D and then copying it and selling it for less.
If I spend $100K developing a product and then have to recoup that cost along with the cost of manufacturing, someone who has no R&D cost, just manufacturing cost, can sell it for less money and still make a profit.
I just figured that the technology wasn’t patent and was open to everybody to design and sell.
I just figured 3 phase would be a option since most 3 phase items were a little cheaper. You bring up the interesting subject about cost on the power delivery.

Cost me about 25k to switch my shop over to 3 phase that I needed for equipment upgrades and power pole with 3 phase was only 40’ away from my shop.

As mentioned 3 phase is different than 240v. Unless you live in a 3rd world country you have 240v in your panel already. Your dryer, range and Ac run on it. I hung a 240v on the wall right beside my panel (about 10" away) for less than $50 in about an hour. It's really easy and there are plenty of youtube videos to help. If you aren't comfortable an electrician should be able to do it for you reasonably.

Sent from my iPhone using Tapatalk[/QUOTE said:3 phase motors sell cheap because only commercial and farm will have 3 phase, usually. We live 250' from a farm and can't get 3 phase without HUGE expense. It is not run on our poles in this neighborhood and might have to come several x000 ft from where it is to here, plus the transformers.
So why bother. If you live in farm country or in the middle of an oil field, it might be a bit easier if you see a lot of poles with three transformers on them. If not, best forget it IMHO.
I use a 2 HP VFD to run my 1 HP 3 phase mill - works great. Converts 240V to 3 phase 240V with full power.
240 in your garage could be no more hassle than moving some outlet or light circuits to tandem breakers to free up a space for a 30A 240V breaker, then running wire surface mount or in conduit.
This is what 3 phase would look like on a pole

I was looking at other scroll compressors online and one manufacturer said in a video that there was no oil between the scrolls. Then after I posted that, I watched the video on Eastwood's website that mentioned a synthetic oil between the scrolls, but my post was already out there. I wonder if the first source was incorrect or if different manufacturers use different methods?
True. This is very common in China, and not just with other manufacturers copying a design or patent. Factories over there commonly produce more goods than are required in a Western company's contract and sell the other product to be rebranded and sold in other markets. The Chinese love to use economies of scale to make more of something and make some side money.

The technology of a screw compressor isn't patented, but the specific design that Eastwood has put together likely is. The problem is that so many factories in China just duplicate other things. Rather than doing the R&D to make a product, they just buy someone else's, disassemble it, and copy it - most often using cheaper materials and cutting corners where they can to save a dime. So you save $40 and the company who originally designed the product goes bankrupt.

Any plans to make a larger version of this? It seems extremely efficient, but I would be looking for something along the lines of 25scfm.

There are many Chinese firms making exact copies of other products and seeking them with another company’s name on them. They even do it if there is a patent as many companies cannot afford a lawyer to fight a company in China.
It has gotten so bad with certain items that it almost impossible to buy the genuine item with so many fakes. Some companies have gone to direct sales only or simply not warranting anything bought on Amazon or EBay. In some cases they only warranty items bought from a select few resellers. The problem is people think they bought the real thing and want the company to warranty an item that they didn’t make.

We always do our best to listen to our customers to expand and improve product lines if we get enough requests (if we can still keep the product affordable and to match our quality specifications!). We have spec'ed out a larger unit that we may produce after we get the QST 30/60 out on the market for a little while. The next unit would be able to handle a large professional shop more adequately.
Just a heads up for GJ Members- We have had an incredible amount of interest in the compressors in just a week and our first shipment is about spoken for! Waiting even a few weeks to pre-order could put you out to late winter/early Spring for delivery if your compressor ends up being on the second or third shipment.
AKA- Don't sleep on the pre-order!
Thanks,

Scroll compressors are not new.
"Léon Creux first patented a scroll compressor in 1905 in France and the US (Patent number 801182). Creux invented the compressor as a rotary steam engine concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype since a scroll compressor demands very tight tolerances to function effectively. The first practical scroll compressors did not appear on the market until after World War II when higher-precision machine tools enabled their construction. They were not commercially produced for air conditioning until the early 1980s."
Wikipedia

Waiting for a compressor while blasting is a no go for me. Nothing against this particular unit, but if you do any significant blasting, you will want a larger CFM capable unit. Kudos to EW for bringing out a nice scroll unit.

I guess everybody wants bigger but I'm curious if there will be a slightly smaller unit that can run off of 110v planned for the future?
Like someone else said, if the $200 gift card could be used for free shipping instead, I think I'd take the chance and pre-order one

You've got to be kidding me. It is a cultural difference. They don't view it as ripping off, though clearly, it is. They value "harmony and stability" far more than IP developed by an individual(person or company). These are highly ingrained vestiges of a communistic legacy.
Interesting article:

Well I think everyone helps contcontribute to this and Chinese people aren’t the ones to blame for it entirely. Greedy corporation want max profit and cheaper labor, so they put out source it to China. Why not keep the production in the US? We all take part one way or another. I may not agree with it but it happens.

My shop has single phase, the THIRD Leg Transformer is only 16' from the load box, Would require a connect at the pole, and a different meter...
The Electric company wants $15k to do the upgrade... I could and AM qualified to make the connections and the wire is already there, but no 3p meter...

Several reasons. competition is one. After WW2 we gave the Japanese the technology to build things. Their cheap labor, work ethic and a fighting culture beat us at our own game. For example Matsushita's buys Motorola's Quasar TV division.
A second factor is you are not left holding legacy factories and equipment when consumers taste or technologies change. It's a lot more efficient to let another country deal with those problems.

Well I pulled the trigger last night....now I wait.
Good deal. I am still on the fence with the 12 cfm rating, if it was up 5 cfm I would probably order. As mentioned the $200 gift card would better served with free shipping.
So here is a question for Eastwood.
Since these are imported, even at your quality level, I expect there would be a certain % that will be figured as bad or have issues. If that is the case and you are selling what you have in stock, based on the previous statement above, what happens with the guy who gets one of those that fail? If all are spoken for does that mean that guy will have to wait for the next slow boat to come in? I am not trying to criticize you, just being in Mfg for 40 years makes me what to know the plan. Sometimes with a new product a common parts may not hold up and need a revision, how will spare parts be handled?
Thank you

A very valid question. Our QC team will be opening every compressor and testing them here in our headquarters in Pottstown, PA. before they actually leave the warehouse.
All of our service and repair parts should be in stock when Pre-Sale customers receive their compressors. Our QC team monitors warranty issues on all of our products and if we see a rise in a certain repair part or returns on a product we always review the issue to see if a working upgrade can be made. Other times we offer an upgraded replacement part available if a working change can't be made during manufacturing.
Hope that helps,
Matt/EW

I don't typically give to much weight to reviews where the product was given to the reviewer for free. It's not that I don't trust Ryan to give an honest accurate review, but if the company knows that a particular unit is going to be reviewed, they are going to go over it with a fine tooth comb before shipping it. So the unit Ryan got may not have been representative of the typical quality for these units.

The pre-sale deal will run until the end of the year. After that it will be the full price with no rebate/discount. I can assure you that a larger unit won't be available that quickly. Just in the time it takes to go back and forth on samples and getting geared up to mass produce takes months and that doesn't include testing, shipping damage testing, etc.
The unit we sent to Ryan has been a sample that has been getting torture tested by us and a number of professional shops for months. If anything it was more prone to failing for Ryan because it had so many hours of use on it already. The compressor in the review is a final sample that is 99% the same as a production unit (barring maybe some sticker/graphics, etc. changes) so the unit a customer will receive will be the same in performance and quality.
It isn't in our best interest to bait and switch with a product like this. Just the cost of refunding and paying return freight shipping costs would be detrimental to being a profitable business.
We could use every compressor and beat the **** out of it for months before sending it to a customer, but we don't think everyone would like a "well loved" compressor at new pricing....
Thanks for all of the interest and questions here and in PM's!

Ok I have finally decided on a new compressor and ordered one of these. Timing wise it should about right for Jan. I will be setting up my new shop during Xmas break.
If this compressor does half or what I see on the videos I will be happy. I like the portability aspect, the low noise level and think 12 cfm will work for what I do- hand tools and blasting corvette steering boxes doesn't take more then 20 minutes.
I also based my decision on being a Eastwoods customer for over 20 years. I will review this machine when I get it and put it to use. I will be brutally honest on that as well, but if that shop video was 100% accurate where it was used in a full resto shop then it should be good for me. We'll see.
One note to those who may order. I ordered but made the mistake of using a commercial address with a dock. Part of the shipping cost includes a lift gate delivery so I requested a ship to address change and that will save me transporting it to my new shop. That is worth about $75 so the $200 shipping fee is fairly based, at least for me.
I look forward to using this machine and hope the lead times are not pushed back too far. I am very familiar with lead times changing and unlike some in the corvette rebuilding game I never book a job, lie to a customer, and then ignore their attempts to reach me with questions. I hope that Eastwood does not follow that practice as well. I have no reason to believe they will but please respond on this forum so others will know.

As it happens, my 11 cfm, 60 gallon compressor developed a leak in the tank this week. I thought it was the drain-****, but it is coming from one leg, welded to the tank. Whether a result of welding error, or 5 years of vibration, I don't know. I use my compressor daily, at about a 60% duty cycle, in a small production shop with 1-2 people. The primary use is a cnc plasma table and handheld air tools. When I have both going, this compressor gets very little idle time.
Since I lean on it so hard, I was immediately uncomfortable with even considering a repair on the tank. It is drained regularly, and often, but it's one of the most critical parts of my daily operation. Being a little undersized, I started shopping for an upgrade. In fact, I spent the afternoon shopping and visiting with other shop guys about their preferences, experience and insight. I had pretty much decided on a new EMAX two-stage piston compressor, rated 19 cfm @90 psi, with an 80 gallon tank. It is also rated for 60% duty cycle, with continuous run options. That should easily handle my needs, with room to run my blasting cabinet occasionally. I also had set my mind to spend an extra $400, or so, for the quiet intake system, rated at 58db. That's quiet! It does have a belt drive, and disc valves, though, so I'm skeptical as to how quiet it really is. I decided to log on to GJ to see if anyone else had any info about it, but was fully prepared to order one tonight.
And then Ryan posts this story! It didn't take long for me to reconsider. I figured out the scroll compressor quickly enough. That's old tech in the HVAC world. Oil injection on the front, and separation on the discharge, is standard on any screw type compressor, so that's not scary. What I really like is the complete lack of reed valves, disc valves, pistons, rods, etc.! That's awesome! I decided to take a chance on the lower cfm, vs my goal, but I'll still have a second compressor on standby, so I needn't place the combined load on this one, if we get busy. So.... I ordered one. I think it will be great for 90% of my work, and I'm prepared to see how it goes on that last 10%. Thanks Ryan!
sidebar: I actually have a 32 cfm rotary screw compressor, but no 3 phase power. The phase converter required for a 10HP motor would be about $3500, and a single phase motor would run well over $1000, plus installation. So, if you're in the market, hit me up. It's in great shape, with a known history, and only 3500 hrs on it.

Matt, looks **** a nice compressor. As someone who has spent 30+ years in the machinery business, I know what it takes to design, build, test, and introduce a new product. Kudos to the Eastwood team for the successful product launch!
I agree with many of the comments here about shipping costs. I'm used to free shipping on $99+ from Speedway and Summit (or flat-rate shipping from other sites.) and Eastwood's shipping charges have sent me elsewhere on many purchases...
I wish you were more competitive on shipping, you have a great product range, with many products I use regularly.

Thank you for the kind words. Product launches with larger, heavier, and more expensive products always take a lot more time and have a lot of moving parts to go off smoothly. We are happy most people see the benefit of the QST!
We definitely will look at the shipping charges. Sometimes the shipping cost for some products to ship free eats up our profit and we aren't making any money. In the end of the day we need to make profits to keep the business running and we do need to charge shipping. We're constantly looking at ways to ship more affordably, if you have any products in particular that you feel are too expensive to ship feel free to PM those to me and I'll take a look!
