I saw a video from India I think where they took two regular high pressure hand pumps and had a huge flywheel that was driven by a jackshaft and then an electric motor. So elegant and effective I must say I've been gathering parts to make my own. Thanks for the video
Minor adjustments to the counter balance so it doesn't go for a walk but otherwise it's a great build especially with the extra features like thermostat and safety glass.
This vid deserves a lot mor views. Fine job sir.
Just finished watching it. That was very kind of you to lay it all out. I appreciate it. I suppose you own or have access to a lathe and mill. Im saving for a metal lathe, then im going to build a vertical mill and eventually my own 300 bar pcp compressor. Thank you again!
Hi.
Look at my first pcp compressor video .
There are any information.
But why do not giveing description of the accessories or metrials pls give me that link of parts and how to make it
High quality work. This took lots of thought, to pull off.
Fantastic build. Design and video.
Wow! Impressive, thanks for sharing. Great video detail walking through the assembly and parts.
Thanks for watching
Excellent video and thank you for sharing 👍.
Both pistons seem to make compression on the same time , shouldn’t they be 180 offset ?…
So if 1 piston is compressing the other one is open or at suction ?….
Or can it be in this sett up because the difference in piston diameter ?.
Is there more information to be found somewhere on the how and why ?….
Thanks again for a great diy project 😀
OK interesting, thanks, as I understand it this is a dual stage compressor, fed with 8Bar from another compressor...
Nice work.
Yes
Are you willing to share cad drawings of your parts? And parts list like seal sizes and o ring sizes?
Hi Paul
You fantastic work.
I have a FX Impact. Using a cheap China compressor. After seeing your compressor design I would like to build my next one. I have the tooling covered, Okuma mill and lathe.
Would you have drawings are list of your design?
Don
Beautiful work my good sir! A+.. all im down is a lathe been wanting one.. maybe this motivate me..
Hi Paul. Very nice project. I am also making one. Can you please share me the size, material used in the block and piston. Also please tell motor hp and wheel size
How long did it takes to fill up the bottle and at what PSI did you stop it?
HELLO, EXCUSE MY DARE, BUT IT WOULD BE POSSIBLE THAT YOU CAN GIVE THE DRAWINGS OF THE CYLINDER ASSEMBLY, I WOULD LIKE TO MAKE ME ONE. I THANK YOU VERY MUCH, GREATEST GREETINGS FROM ARGENTINA
Does the counterbalance serve any purpose? The motion of the pistons is driven by an electric motor… why the counterbalance? You might find thermal grease (on the cooling rings) would improve heat dissipation… but really, the detail on the cylinders is brilliant!
What was the total value in cost for the build? That is a awesome build worthy of construction an most likely move durable than the pumps available to buy.
80eur
Material aus dem VEB mitgenommen, denke ich mal.
I prefer using thermalpaste in heat plate installation, it will improve the heat dissipation much better.
You can find it in computer or electrical parts store for sure.
I dont understand how the regulator/. Oil water separator works when its on the inlet side.. or why the high pressure line wasent used on its connection., wouldnt that too be at high pressure if its reading the pressure in the system? No comprende
Have you posted a parts list and diagrams for this build ?
Excellent job. I can see where it pushes the air out but where does it draw the air in from?
Thanks.
Classic compressor - help with 8bar
did you make the check valves? or you buy them?
I made the check valves.
Excelente, enfriamiento para los pistones, piensas en todo.
Could make some amazing explosions
This is beautiful
Do you have some video with sealings assembly? Would be interesting to see that part. Thank you!
I don't have it at the moment.
@@PaulXchannel Ok. Thank you in any way. And what is the diameter of pistons ? 1st and 2nd stage you are using?
First piston 10mm .
Second piston 6mm.
Stroke 120mm.
Very nice! I understand check valves on intake to prevent exiting during compression, but where are check valves on exit to prevent compressed ait back into cylinder? Are they inside that cap that you screwed on cylinder top? Is piston made on lathe have you some idea to improvise it without lathe etc. Overal great construction.
the piston is a carbide semi-finished product - it is not machined
@@PaulXchannel So where you found it? Yup, carbides are hard but that rod before must have been lathed

@@PaulXchannel thank you
Wow just Wow!
I hope there is a video regarding that sweet spanner wrench you have @ 3:29 in the video. Loving your channel, just stumbled on it this morning : )
Well thank you.
I made the key in my workshop.
Unfortunately I don't have a video with him.
Hello, if you were to use opposing cylinders, do you think it would work twice as quick?
in the same way
You're feeding it with pressurised air? At what pressure? 100psi?
8bar
Awesome Paul! You're a pal thank you for the video! Haha Excellent!
Thanks
Hi, Very nice job! Congrat! What is diameter of piston shaft first and second stage? And movement lenght (stroke)? The piston itself looks like aluminum with brass on top, am i correct?
Thanks.
First piston 10mm .
Second piston 6mm.
Stroke 120mm.
Material of pistons solid carbide rod.
@@PaulXchannel Ok thank you. And at second 0.54 of movie we can see two brass pieces with side hole ( i supose hole goes in 90º till top where spring sits). - Are this pieces one way valves sit on top of cilinder? How do they seal? Have o-ring or another kind of sellant inside cilinder?
@@paulosoarescarvalho6219 Yes. There are one-way valves with 90° hole.
@@PaulXchannel How do you did one-way valves seal? with o-ring? And where is that seal? Inside cilinder?
@@paulosoarescarvalho6219 A plastic ring.
In first part . ( cylinder head )
success for "Paul X"
Do you have the scheme of this machine?
Dear Paul. It was really a nice job!!!! Congrats!!!! have you used stainless steel to manufacture the cyliders?
Thanks .
The cylinders are from aluminium.
The pistons are solid carbide rod.
Well done that man
This is BRILLIANT! Subbed
What is the stroke and plunger diameter in both stages? Motor power?
6mm 10mm 100mm 1.5kw
linear guide? HGR25 or 30? shit, this thing must have cost about 5k USD. no way I will DIY such a machine, just saw PCP air compressor on aliexpress at 158 USD. , 4500 PSI pressure, free shipping
Tolles Video und Projekt!
War sicher viel Arbeit, was hat dich das ganze an Zeit und Geld ca gekostet?
Wie lange hat es gedauert, bis der Druck in der Flasche auf 3500psi war?
Viele danke.
Ich habe das Geld nicht gezählt es ist ein Hobby.
Füllzeit eine halbe Stunde.
Hi. Pistons are 10mm and 6mm. But what are the diameters of cylinders?
inner diameters I mean
10.1 ...... 6.1
Thanks! Do you filter oil from air after high pressure compression?
@PaulXChannel
I don't filter
Simple design would have went with some bigger pistons though and a multi stage design though
No you wouldn't of
If you look carefully you may notice that Paul is feeding the high pressure compressor from his low pressure compressor (~7 bar). Also, the rods/pistons of the high pressure compressor are different diameters, suggesting that the high pressure compressor itself has 2 stages - altogether that makes 3 stages.
If you wanted bigger pistons delivering 300 bar pressure, you'd need a *very* powerful motor! Remembering from physics class:
force = pressure * area
and suppose you want a 50 mm diameter piston on the final stage:
pressure = 300 bar
diameter = 50 millimeter
radius = diameter /2 = 0.025 m
area = PI * radius ^ 2 = 0.0019635 m^2
force = pressure * area = 58904.9 N (13,242 lbf or 6.6 tons)
and that only accounts for the final stage - Yikes!
As Nikola Tesla once said of Thomas Edison, "His [Thomas Edison] method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 per cent of the labor."
No sólo saber los componentes, sino donde comprarlos
Excellent design. Do you sell these? Did you make or purchase all the parts?
Thanks,
Paul
Made in my workshop
Damn!
Самое главное что молчит, и так всё понятно.
Молодец!
Just wondering, how hot could your cylinders get without the cooling rings?
I think if I turn off the two fans it's about 65-70 degrees celsius.
@@PaulXchannel Do you think that is because of the friction of the compressor moving back and forth, or the compression of the air?
Large rotating mass.
@@PaulXchannel thanks 👍
@@tylerdurdencotw I'm not sure Paul understood your question, so as a mechanical engineer I'll note that compressing air makes it hotter according to the ideal gas law:
en.wikipedia.org/wiki/Ideal_gas_law
Solving for temperature, you get
T= (PV)/(nR)
I suspect heat due to friction is negligible compared to heat from compressing the air.
Very impressive and interesting setup you got. How fast can you get 300 bar pressure in a 2 gallon tank? Can you make a higher grade faster compressor if ordered?
Thanks for watching.
I don't have a measured filling time.
Approx 2-3h.
I would ask if you build to order but the $$$$$$ would be that of a nice sports car, lol.
No, I'm not building.
Super!👍👏
How much I will take 1
Not for sale.
Thanks for watching.
What kind of “glue” in assembly?
Thanks
I don't use any glue - only oil on the O rings.
@@PaulXchannel what oil? Silicone oil?
@@bangagih It can also be machine oil. Mixed into the air in the device.
Can it be water cooled?
Now only with air
飞轮太小，重量太轻，所以运转时空压机老是抖动
плохо вышло ( , правда
I will buy it off you. Please let me know if it's for sell?
Sorry but isn't for sale.
@@PaulXchannel. Hi Paul, thats a nice system and I would like to know if you would sell the necessary parts so I can put on together?
And how much would this unit cost if it was ever build with that intention?
Thank you for watching.
Unfortunately I have little time to make new parts.
👏🏻👏🏻👏🏻
Di sade mboten kang?
Muy buen compresor, pero me gustaría saber los componentes para hacerme uno. Gracias
Hola! Cómo estás? Dónde vives? Para piensas usar algo como esto? El fabricó casi todos los componentes.
Cuanto cuesta el kit completo
@@antoniolaracalvache7676 Antonio en que país estás ? Tu puedes comprar un compresor desde los 300$ -3000$ dólares, para qué tipo de uso lo quieres y así te puedo recomendar algo y no tienes que pasar trabajo
España, y el compresor lo quiero para una carabina PCP.
Ya se que los venden hechos, pero me gustaría hacerme uno y así me sirve de entretenimiento
@@antoniolaracalvache7676 le voy a preguntar si él te puede fabricar los pistones y las válvulas, pero no te recomiendo eso te sale más caro solo el envío a España va a costar unos cien dólares, sabes que este sistema tiene un compresor regular conectado? Esto es como un multi picador, busca un aparato llamado shoebox.
How much did this build cost you? Thanks
I don't know. It is a hobby. I did not count the cost :)
@@PaulXchannel oh thanks, i converted paintball to bolt action rifle, and i made a compressor from an old fridge, but the power wasn't sufficient. I have a lathe and a mill, but I dont have the money cuz Im 18 years old. I mean if its around 200 euros its not expensive. Thanks for the information Im gonna try to build it if its not that expensive
I wish you a lot of success in the construction - thumbs up for people like you.
@@PaulXchannel thank you, it means a lot
Is this available for sale
Not for sale.
Thanks.
Our brand would like to invite you to test our products for free, how can we get in touch with you?
A car ac unit will do 350psi why wouldn't you use one of those
I'm sorry, it's just a hobby.
@@PaulXchannel ok cool I use to make stuff but if I can repurpose stuff I will now time vs money hard to have both
@@markhall912 O.K.
Cheers.
This unit will allow you to have 10times that pressure, I don't know why he built one but I can tell you how useful it can be to many, people with off-road vehicles have to deflate and inflate back and forth their tires a 3000-4500psi air tank allow them to do this during the whole trip. Another use for hobbies like, Air rifles PCP to 2000-4650psi, Paintball hpa makers, some airsoft guns and for the lowest end using between 200-800psi water rockets.
You could use it for scuba diving, but you will need to have a very nice system of filters to ensure the air is clean and safe to your health.
I personally would like to have one for my PCP rifles.
350 Psi = 24, ..Bar
🖖 👍
No filters i wauld love to see how much water come out in the tank .!! Coz i use pump to fill my guns and iv seen shit loads ov water in my guns coz filter gets wet over time .!! Fuck that tank going bang !!! Coz rust eating in side out 😂
👏🏻👏🏻👏🏻
