How a scroll works.
A scroll compressor has only one moving part -the rotating scroll.
The rotating scroll is moved in an elliptical pattern by the electric motor output shaft inside of a corresponding stationary scroll. The elliptical movement pulls air in from the outer edges and efficiently compressor the air charge toward the center of the scroll. This constant displacement pump design reaches 100% volumetric efficiency and ultra-quiet operation with minimal components.
A piston compressor utilizes many components to drive a position in reciprocating motion up and down in the cylinder. As the piston moves down in the cylinder a valve is displaced and allows air to enter, the piston then changes direction and compresses the air charge and expels the majority but not all the charge out the exhaust valve. In theory, the piston compressor can never reach 100 % volumetric efficiency as there will always be a small amount of air left in the cylinder as the piston can never touch the top of the cylinder to due mechanical interference.
The constant change in piston direction, rotating crankshaft, metal on metal of the piston rings and cylinder wall and intake valve fluctuations all contribute to the annoying load compressor noise we are too familiar with.
Why is a scroll better than a piston?
A scroll compressor is truly 100% volumetrically efficient meaning all the air that is pulled into the intake side is compressed and moved through the exhaust side into the tank. The scroll has only one moving part eliminating the constant wear and blow by associated with piston compressors. The scroll rotates in one direction and is designed to run at 100% duty cycle very efficiently and the reason it only requires a 3.3HP motor to drive the scroll to 12 cfm and the best part…. The lack of noise!
Make a 110v version!!!!!
it's almost like a rotary screw compressor
I like that they removed the cover and explained the internals, very cool.
Poorly designed- friend has one that blows oil all over. Stop selling crap Eastwood
This type of compresores has been used in the air conditioning industry for about 40 years! Better efficiency and less noise.
Good Quality tools from Eastwood Company. You just cant go wrong!
90% of the water does NOT go into the airtank! 90% of the water goes into the OIL tank! be ware people. I fell for this sales pitch myself, but be aware! before you buy check all the youtube videos and the CONS before you buy this unit.
U should put the names of the guys on screen. In Europe, people get to know those persons by name, and as time goes by, the contact between customer and company feels more personal for the customer... Just an opinion. Not knowing the names of the guys feels somewhat generic, at least for europeans. Otherwise, great work !!!
Well I've got the loud one so I'd say I'd rather have the scroll.
Interesting...and I'm going to be needing a new compressor in the near future
I need this in my shop! So tired of my husky breaking my ear drums! Will shipping be fast so i can get this in my basement before it snows
PISTON is stil N°1, (oil free) scrol compressor are / is ~good, simple to assemble but with a very short lifespan compared to a piston compressor.(N°1) screw (N°2) direct drive "NO FREQUENCE TYPE", The idial circumferential speed of a screw compressor determines the efficiency of the compressor element !!!
Where do you get the idea that piston and other types of compressors don't use oil? No oil and they'll seize in about 5 seconds.
@@GGigabiteM You have many type of oil free compressors, and YES also 'piston type' mostly sell scroll type (AC) and at high power compressors the Z series from (AC) Atlas Copco., are usually powers of ~200Amp and +++.
Because these are expensive machines, in EU (Europe) oil injected compressors are often used with spectial "food grade oil"
This is amazing! I just built my 30x40 garage/shop this summer and I have been eyeing everything for "shop" equipment and man I really like this small package as long as it could run a 3/4" impact if I absolutely had to but from your video I shouldn't have issues at all! I would love to win one but am definitely looking at making the purchase when they come out!!
I don't like that it wont plum in to a air systems and its only 1/2 coming out my shop has 3/4 with high flow fitting with 1/2 hose for max air volume ! They said it will last for 100 K but with the motor hold up and every thing else ?
@@johnversluis3084 I've been picking up on that slightly deceptive marketing scheme about these qst. While I'll likely be buying the qst 80/120 I know the motor will be considered as a consumable in a sense compared to the compressor itself.
@@zedsdead7670 For the target market of this device, motors are always a consumable. Comparable single and dual stage recip units will also kill motors just as quickly.
Do want.
The scroll one because it's quieter
So air conditioner compressors to compress air.
How does this compare to the emax 7.5 HP?
Didn't VW make something similar to this?!?
Looks very nice. Will it run on 208vac 1ph? Will the filters be available through sources other than Easwood? Thank You.
Jay - Yes it will run on 208VAC, 1ph but 240VAC is the most efficient. To answer your 2nd question, currently the replacement filters are only available through Eastwood because we want to make sure the quality filters installed on the unit meet our specifications. Hope this helps. Thanks for the interest.
I'd argue that using 'innovative' as a descriptor of technology over the course of a century, tapers in accuracy. In which case 'innovative' has completely expired at this point. Perhaps innovation should be focused on relative cost for performance.
Applying old technology to a new area is innovation.
If you cut open a window air conditioner or a home refrigerator, they run scroll compressors. Some cars are now doing it.
So it is quiet. But $1500? 240V?
Incredibly quiet. We used it to blast a Camaro and had no issues. It was very impressive.

The tank on the Eastwood Scroll Compressor was designed with ½” fittings consistent with home shop use. As for the 100,000 hour scroll life, that is for the scroll compressor pump itself. The motor is warrantied for 2 years when wired to a circuit output of 220-240VAC. Hope this helps.
what I didn't hear covered is the "oil, oil filter, air filter and moisture separator change interval" I see there was a fancy sticker explaining it, but not covered in the video,and is there an hour meter..
We recommend changing the oil and filter every year. The oil can be purchased from Eastwood (which we recommend), but if you don't get your oil from Eastwood, you MUST be sure to use synthetic scroll / screw compressor oil.
It drives all of your tools because it is designed for 100 duty cycle. How does its electric consumption compare to a 60 gallon traditional running for less time?
Brian, let's assume the electric rate is $0.16/KW Hour. The Eastwood Scroll Compressor at 240v with the 3.3 HP motor equates to 2461 watts. Convert this to KW and multiply by $0.16 and you will have $0.39 to operate per hour. A typical 60 Gallon Piston Compressor at 240v with a 5hp motor equates to 3730 watts. Convert to KW and multiply and you have $0.59 cost to operate per hour. This means the Eastwood QST 30/60 Scroll Compressor not only saves you money when you buy it, it saves you money every time you use it! Plus it isn't much louder than a Central Air Unit. It barely makes any noise.
Its a good time to need a new compressor! My CAT is fantastic for being quiet but just doesnt have the volume I need for the CNC. Cant wait for this to launch, will have mine on order soon for sure.
Available for order November 1 and you will get a $200 gift card with the purchase. it will ship in December 2017.
How much run time have you guys put on these? Are you confident they will last 20+ years like other high quality compressors?
Here's more info, plus a link to e-mail our engineers with questions: www.eastwood.com/scroll-compressors
genius
now I feel kinda stupid for buying a 5hp compressor. Does this compressor have the ability to upgrade motors to something like 5hp? Can it scale up to handle something closer to 18-20cfm at 90psi?
Joshua - The Eastwood QST 30/60 Scroll Cmopressor is a direct drive motor/pump assembly and the HP and motor rpm are tailored to produce the 12 cfm and 145 max psi in the most efficient and energy saving package. We do not recommend moving to a larger motor as no benefit in cfm or max pressure will be realized, just a higher energy cost. Larger units could possibly be available in the future.
The moment you release a larger one you have me as a customer.
Take my money! How much and when available?
Coming very soon! Follow the link to Eastwood to sign up to win and be notified when it's available.
Thank you! Signed up and following.
@ 2:28 "these pieces never touch" so they hope :))
Rheem,Ruud A/C?
How much? 1500? 2000?
Check it out here: www.eastwood.com/scroll-compressors
The price jumps all over the place. Seems like they are testing the market to see how much they can get for it.
Check out how much their shipping and compressor oil costs.
How would this work in a body shop setting does it get more oil in the air lines than a conventional or less and how good is it at running a spray gun for entire vehicle paint jobs any issues with that
Kyle Good question . Also how much water gets into the line and how hot does the air coming out?
Ahmad Boone well hopefully I win it and can find out lol
Kyle, that is a tough question because there are a few factors to consider like age of the compressor and ring wear. But let's assume you have a fairly new piston compressor. The Eastwood QST 30/60 Scroll Compressor has a very efficient oil/air separation circuit and filter to remove the majority of oil and moisture, however we still recommend an external oil/moisture filtration system, just as you would have on a standard compressor system. To answer the 2nd question, the 30/60 Scroll Compressor will feed up to a 12 cfm HVLP Paint Gun enough air to paint a vehicle at 45 psi to the gun. Hope this helps. Thanks for the interest .
Convinced. I ordered one to run my Haas vertical machining center. I’ve been having a hard time keeping up with it’s air requirements.
Lacks the maximum running pressure information. My bet it 100psi or less.
Keep the scroll from letting tank pressure leaking by.
3HP unit given it pulls 15 amps at 220V. Of course the output is less than the 5hp piston compressor which are typically rated at 17 cfm.
Comparing compressor holding tank size? Give me a break. Its hp to cfm. Tank size has nothing to do with it.
Only real information is the DB rating and the fact the motor is 220V.
Also listed the compressor RPM as 3000? No induction motor runs that speed, what give there?
Quite, Ill give you that. Give me the price and where it's manufactured and Ill tell you if it will sell.
