The Eastwood QST-30/60

Well, being a numbers guy, I decided to do some math based on the time to fill that Ryan reported, vs my existing compressor.
I compensated for tank capacity, atmospheric pressure, and cut-off pressure.
My 3.7hp single stage compressor required 8:55 (8.92 min) to fill 86 gallons to 155 psi (10.69 bar, 10.55 atmospheres)
The QST-30/60 required 2:38 (2.63 min) to fill 30 gallons to 145 psi (10 bar, 9.87 atmospheres)

So, my compressor filled 141 cubic feet in 8.92 minutes, at a rate of 16 cfm. If we deduct the 1 atmosphere already in the tanks, it was actually 14.32 cfm...
(86 gal = 13.38 ft3 x 10.55 atm = 141.15 ft3)÷8.92 min = 16 ft3/min

The same math for the QST-30/60 went like this...
(30 gal = 4.67 ft3 x 9.87 atm = 46.06 ft3) ÷ 2.63 min = 17.5 ft3/min
Again, allowing for 1 atm already in the tank, it still comes to 15.7 cfm.

By the numbers, the QST-30/60 is outperforming my noisy 3.7hp, 60 gallon compressor by 10%. Keep in mind, this is an average flow between 0 and ~10 bar. It shouldn't be compared to flow measured at 40 psi, 90 psi, etc.
I think Eastwood is onto something by claiming performance of a 60 gallon class in a 30 gallon package. They could have easily dropped this pump on a 60 gallon tank and claimed it was a competitive performer, at much lower noise levels, but putting it on a smaller tank, and wheels, it has created a whole new class of compressor.
I can't wait to try it. And , Matt, my shop is working around a wounded soldier, so if you want to bump my order up a little, I won't tell. It can be our secret.

Matt, I am looking forward to Scotty getting his compressor too because that means I can go by his shop and test the flavorade and see how quiet this beast realy is!!!!

If I was outfitting an auto/metal working/welding home shop, this is almost a no-brainer, assuming the durability is there.

Some tools and operations I simply have not done at home because the cost of the electric corded versions of the tools are prohibitive considering the infrequent use they would get, or the compressor would take up too much room and would be too loud once I do use the tools: nibbler, shears, plasma cutter, pneumatic/hydraulic press and bender.

I would be tempted to replace a few of my regular corded/cordless tools that are regularly used with pneumatic equivalents as well for the smaller form factor and lighter weight.

For now, I'll keep a close eye on long-term durability.

At the end of the day, it is in built in China, and it’s promoted here??? Why? 100,000 hour run time??? We Can’t avoid China, but we need to try.

I’d rather buy something 10 years old (even if it was made in China or NA) and repurpose it. It keeps me employed, keeps a few dozen suppliers involved employed.

Hey everybody, let’s buy this scroll, let’s bump this thread and let’s just eat rice next week, as that’s all we can afford.

Buy one and brag about it. Post away with your experience.

Why don’t you just shoot yourself in the foot.

You have to accept the fact that this is what things are coming to. Your phone, coffee pot, tv and probably a number of other things you own are all made there but it's not advertised or marked so you probably don't pay much attention to it.

Even if it wasn't made there you have to remember that some part of it, component etc will be made from there or some other country. There is pretty much nothing that will be made in usa with all usa made parts...or are you going to ***** if it's made in usa and a chinese person assembled it in the usa?

Big companies are all about making money. They aren't going to make it here, spend twice as much just to say it's made in USA because the amount of people that are willing to spend double the price because of that sticker won't justify it for the business selling them.

AS long as the stickers say made in the USA anything can continue to be made in the USA, just like all the Japanese car companies like to say made in the USA now.

I’m in the last stages of completing my new garage and needed to replace my old Sears Craftsman 30 gallon compressor with something larger, but also because it developed a leak in the bottom of the tank, despite being properly maintained. So Last month I ordered this new Eastwood QST-30/60 compressor.

I’m impressed by it’s efficiency, but I’m interested mainly it’s quietness. In the past year my hearing loss has become quite severe to the point where I now use hearing aids and have also developed tinnitus. Hearing loss is cumulative, so do yourself a favor and wear the best protection you can. Diminished hearing is one thing, but tinnitus has the potential to destroy you.

Anyway, I’m really looking forward to the delivery of my new compressor and if it’s as good as reported, I’ll be very happy.

Matt,


So the $200 gift card deal is still valid until the end of December? I hope so, but the website says otherwise...with that gift card deal I am all in for the compressor. Please advise...thanks!

I got my gift card yesterday.....and spent it already

Unfortunately the Pre-Sale has been closed due to us selling out of our first two shipments of compressors. This is a rare occasion in which we were overwhelmed with the interest and the allocated Pre-Sale units were sold quicker than we forecasted. We didn't want to have pre-sale customers waiting 6+ months for a unit. We're still taking orders at the full price with no promotional gift card, but they're being quoted for a March-April delivery and not being called a Pre-Sale with delivery in January.

I apologize for the inconvenience. Honestly I'm bummed myself as I can't get even get one for my own shop until we get through the back orders! Times are tough!

Sorry about my rant, I guess you really don’t see the big scheme of things. Let me start off with I don’t mind China and some of China’s productions.

I produced for China for many years building dies drop form dies... Japan, Sweden, Hungry, Yugoslavia, Germany, Mexico, Check Republic, and even the Middle East,

i’ve lost many North American employees to go to China for 2-3 years at $100,000 US per year to train with a free lunch card and accommodations.

United States soil is being purchased by which nation nation number one? (Exclude the Canadians, they’re just coming down there to Die and to spend $ in the state of Florida)

The owner of the company who is manufacturing this compressor, just bought the trailer park you live in. (or your employees live in.) They’ve just been given a 90 day evection. A $20 billion high-rise is going to be built. Enjoy your new investment.

Obviously some electronics nobody is going to build a iPhone or toaster on north American soil. It’s just stupid. This is where comes down to the millennial’s.

The millennial‘s have been given a Silverspoon. They will inherit everything you worked hard for. They will bye Chinese to get them selves by. They will buy the cheapest and they don’t care where it is made. They’re on a fixed income. The income you gave them when you die.

I’ve tried to give certain millennials a $20 (start) an hour job to surrender their phone at the door (in their locker) for 12 hour shift.

I built our Family cottage with my brother my dad and myself. I started at 14 and I finished at 18 years old. It was a four year build.

I gave my dad $1000 towards the purchase of the property from my paper route. The property was $7000.

At the end four years everything I made on my paper route went towards this cottage. I built things will my buddies partied!

At the end of the day I hang out with doctors, lawyers, mechanics, industrial mechanics, electricians, industrial electricians, Business men of all sorts, brokers, stockbroker,...

I didn’t quite like where the North American dustrial trade was going.
(but I found a new love for the industrial mechanic and elevator mechanics and mechanical engineers). 42 years of age I retired. Now I like to try to educate are millennials. You can’t just buy something to fix your ****.

Take your kid and... build a shed, Build a house, build cottage, build it die, fix A car, do a brake job, do an oil job, show him an Oxy-acetylene torch, Any and all welders you have, I can go on with pneumatics, hydraulics, plumbing, sewage, HVAC, shingles, mathematics, drafting, scripive writing, operating a milling machine, operating A lathe (Metal or wood), Table-saw, jointer, planer, teaching AC or DC volts, difference between three phase in single phase, plugs,Outlets, contactors, Disconnects, get in the vehicle license, get a M license, or any motor vehicle license.

At the end of the day, instead of buying just because we can, let’s invest in our kids!

Truck driving encouragement for our offspring, for offshore, is not an investment in my opinion.

Sorry about my rant.

Remember, I do support some electronics being produced overseas! Are millennials will never produce this for two dollars an hour!
My four-year-old and I did a chimney sweep two days ago. But, Who the hell sweeps chimneys anymore?

I guess Google is your best friend. If you’re millennial *****.
At the end of the day who is the beneficiaries of this thread? Just click on this and you will see the top posters are...

Enjoy my thoughts!

I'm not saying you are wrong or anything friend or trying to combat you, and I benefit nothing from this thread other than first hand knowledge of if it is as quiet as advertised, once my friend gets his. If that is the case, as a person who wants to work in a home garage and not be deafened or inconvenienced by a piece of equipment in my garage, this product is of interest. All things compared though, if a US company is coming to market with a unit like this one, with similar specs (for quietness and performance) and pricing, please let me know... I'll be all over it like white on rice.

Scotty: A couple of thoughts on your methodology...

The pressure in a compressor tank is give by gauge pressure and not absolute pressure. No need to subtract ambient pressure unless you want to convert to absolute pressure. If you had an absolute pressure gauge on the compressor, it would read approximately 14-15 psi, when the tank was fully vented.

Second, the typical gauge on a compressor has a tolerance of about 10% at full scale, and it's not linear along the entire gauge. I've run higher quality gauges on a dead weight tester and found them to be under reading in some part of the range while over reading in others. You need to know the calibration curve to be able to calculate the error band at the pressure you are looking at. Without having a calibration curve, you have to assume the max error rate is at all readings.

Lastly, the fill rate on a tank is not linear as it pressure increases. In the numbers you ran, you are not comparing the fill rates to identical pressures. Unless you are comparing the fill rates for the same pressure and correcting for tank temp, gauge calibration, humidity and so on, the two compressors are pretty much a statistical wash.

When I worked in a research lab, all of our pressure transducers had to have calibration curves done fairly often. They included running the calibrations with increasing and decreasing pressures and at various temperatures to determine any hysteresis, as we had to account for possible errors in presented data. For what I was working on, we took approximately 1000 measurements, 24 at a time, in about 500 milliseconds, with only a 100 millisecond band of that being useful data.

Can't get here soon enough!

Mine is fully paid for, have the $200 store coupon and free shipping, just waiting another month or so for the call the machine is being delivered.

Wow - you got both the $200 gift card AND free shipping? How did you manage that? I would have been all over that offer. In fact, I would have been thrilled with one or the other...

That was the original offer for the deal, I think it ended about a month ago?

Here is the original offer, as stated in this thread (post #18) by the Eastwood rep on 11-3-17 (it was supposed to run until 12-31-17 but they sold out):

"It is $1199.99 but with the Pre-Sale you're getting a $200 gift card and no shipping charge ($200 flat charge for shipping) if you pick up in the store."

Based on that information it sounds like you are picking it up at the store; that would explain the free shipping. Enjoy, and let us know what you think of it!

no I was wrong and stand corrected. Sorry I was thinking of something else. It was $1400 with the gift card but the shipping charge included lift gate service I believe.

I am looking forward to using this in my shop with the big test being the blast cabinet.

Waiting for something a little more powerful or a bigger tank but I am interested to see reviews start to come in

We just got our first shipment into our headquarters and we're doing our final QC on each unit before shipping out. If you bought one for local pickup we'll be contacting you as they're ready for pickup and orders will be shipping out by the end of next week or sooner. We're excited to hear some reviews and see these getting put to work in your shops!

-Matt/EW



Our first one leaving today to a local customer that got on the Pre-Sale the first day!

Finally, this type of compressor seems kind of new to me, but I haven't been shopping for compressors lately. Are we about to see several of these types of compressors hit the market? Nothing brings down prices like competition. I might not gag on this price point, but nothing makes me madder than being an early adopter and then finding the same unit for sale from another brand at a much lower price.

any companies offering similar items ?

Any update on when these will be shipping?

Just a quick google search shows other units available ire in the 6k-7k range!

I’ll offer up a quick review of the Eastwood QST-30/60 that was delivered to me last week.

The crate was delivered by XPO Logistics last Thursday. I’ve had deliveries by them before and they have always been reliable. I live in a townhouse (where the compressor was delivered) and my shop is a couple of miles away. We just rolled the crate on a pallet jack from the lift gate on his truck into the back of my pickup. I have a gantry crane at the shop that I used to get the crate out of the truck and onto the floor.

Compressor was crated nicely. No shortage of plywood and foam padding used to protect the unit. No damage at all from shipping. Unbolted the compressor from the crate and used my gantry to lift it up and off the crate. Wheels are already attached. Nothing else to assemble!

Easy to locate the instructions which said to first remove the cover. Removed 4 Allen-head bolts and the powdercoated, metal cover lifted off. Cover felt solid, definitely a thicker gauge metal that I was expecting. The only real indication to me that this is manufactured in China was when I looked over the metal work on the cover. The curved welded portion definitely wasn’t finished very smooth (see pic). It’s definitely more noticeable because of the gloss black powdercoat. I was impressed with all of the plumbing under the cover, it is very neat and tidy (see pics). Instructions said that oil would have to be added before using the first time. I didn’t see any containers of oil and actually went back through the crating to make sure I didn’t miss it. I was about to throw a small fit because I was already missing things until I noticed that the sight glass showed that the compressor already had oil in it. It was showing about 2/3 of the way full. The compressor doesn’t have an electrical plug on the pigtail. I assume it’s to make it easier to hardwire if you choose. I had to run to Lowes for a 3 prong, 240V plug which was easily installed. Instructions said to run turn on the compressor and run for 3 minutes with the drain valve on the bottom of the tank open to purge any water or manufacturing oil that may have accumulated. The valve on the bottom has a petcock with a brass plug screwed into it. The plug was only hand tight, easy to remove but I noticed it was very rusty (see pic). The other issue is that the petcock on the bottom drain valve wouldn’t open all the way because it hits the floor (see pic). Kind of an annoyance but I’m going to add an automatic drain valve so all of this area will probably be re-plumbed anyway. This is all that’s required before firing it up for the first time.

No problems running through the initial purge process the instructions recommend and letting the compressor cycle to maximum capacity (145 lbs.) for the first time. I let it sit for 10-15 minutes looking for any leaks. None were found so I reinstalled the cover (definitely hefty). I bled down the compressor and cycled it several times before calling it a day.

Initial observations… I was surprised how easy it is to move around. The wheels are large enough to roll around on my shop floor without much effort at all even though it weighs more than 300lbs. You would have no problem rolling it around your shop if necessary. Now on to the question everyone has, just how quiet? This thing is the real deal. It’s not “Kaiser compressor quiet” with their insulated cabinets but it is exponentially quieter and a huge improvement over my 15 year-old, 30 gallon Craftsman. The “radiator” end of the compressor is a bit louder than the output end so if you can orient the “radiator” end away from your work space it will be even quieter. I would describe the noise as more of a loudish hum instead of the loud, clattering racket from my old Craftsman. It sounds more like a pool pump than an air compressor if that makes sense. The only pressure regulator I have is for the smaller output on my old Craftsman so I need to purchase a proper-sized regulator and water separator/filter before actually using the compressor. If the compressor lives up to its documented specifications (I have no reason to believe that it won’t), it will certainly handle anything I plan to throw at it! I’m very pleased so far!

So, why did I buy this… I plan on retiring in a couple of years and I’ve been planning/purchasing things for my shop before that time. Part of this exercise is replacing some of the less-expensive, inferior equipment I'm currently using while I’m still working. I’ve already replaced/upgraded welders and plasma cutters among other things. I doubt I would spend $1400 dollars on an air compressor after I retire but it’s easier to justify while I’m still working and firmly believe that this will be the last compressor I’ll ever need. I still think about buying a CNC plasma table before I retire and this compressor would work nicely for that purpose. The shop I’m currently in has more space than I need so I’ll be relocating in a year or so. I was concerned about having to move a large, upright compressor but now I’ll have no issues rolling this new compressor into a trailer. It will also be so nice having a much quieter compressor in a smaller shop.

I give it a thumbs up!

When did you order yours and did you get a call a day or so before so you can be there when delivered?

Thanks for taking the time to give us your initial impressions Mark! Would be great if you could post up your thoughts as the months go by.

I'm pretty sure I ordered mine on 11/7/2017. I got an email on 12/28/2017 from Eastwood that the compressor had shipped.

I got a call from the shipping company (XPO Logistics) on 01/02 and scheduled the delivery for the afternoon of 01/04. They gave me a 4 hour delivery window and I asked that they have the delivery driver call me when he was about an hour from delivery. I work about 10 minutes away from my townhouse so I was only gone from the office about 30 minutes. Pretty smooth process.

Thanks for the review Mark,

When we initially were working on the logistics of shipping the compressor the oil was going to be added by the user and would come separate due to shipping carrier restrictions. We were able to correct that shortly before the final crating. This meant the oil was added by our factory and not by the end user. Our instructions were already printed and that wasn't updated. Our next batch will have some minor changes in wording made to clear any confusion up. Sorry for the mix up there!

We appreciate the feedback and can't wait to see it running your shop!

Our first batch of compressors have been individually QC'ed here in PA and sent out to all of the customers and everyone will be receiving them shortly that made it on that shipment. Our next shipment will be arriving in not too long and we will get those out as well. That should cover all of the pre-sale purchases and anyone that purchased before Mid-Late December. Anyone after that will see a spring time delivery due to manufacturing costs. Thank you for all the interest!

Very cool! Amazing what they can come up with.

Can someone do a DB meter 3 feet away (even on the free iPhone app) as I am curious how it is.
Also what size 220 breaker is everyone going with and how long is the power cord?
I've never owned this type of compressor but how much moisture do you usually get when compared to a traditional one? I have the HF compressed air dryer with my HF 29 gallon compressor. The compressor spits out a TON of moisture but with the m60, and dryer I literally get no moisture from what I can tell and it's awesome. If I get this do I need the compressed air dryer or is that a waste at that point?

It requires at least a 20 amp circuit and I would estimate the power cord length to be 6-7 feet long.

I would keep your HF compressed air dryer, that would make a great setup in my opinion. I'm actually considering buying one to hook to my new compressor.

I'm curious why a db reading at 3 feet is important. I generally work around 20 feet away from my compressor and it was virtually impossible to hear the radio when my old compressor was running. I have no issue at all hearing the radio when I am standing in my normal work area with the new compressor running. If my phone rang while standing next to the new compressor I would probably be inclined to take a couple of steps away from it before I answered. With my old compressor I would have to step outside or turn it off before answering. There's also something about the sound itself that is easier to tolerate. It's just not that vibrating, harsh sound that my old compressor had.

Thanks for the initial impressions, can't wait for some reviews with use!

Thanks for the info, hopefully I should be getting mine pretty soon. BTW, nice X3, I love mine!

I'm not sure why you are responding. I don't want your guess at the length I want to know what it actually is so I can see if it will work or if I have to prep anything before I order one.
Sound is important to me and it give me a better idea of how loud I can expect it compared to what I already have..
