I have the same exact set up, So glad you have this out, I had the same trouble, but before I found this video, another forum had me take the pressure switch out of the head, incorrectly, so I'm high & dry until I get another pressure switch.
Wow, big thanks for this video :) I thought I was going to have to buy a new more expensive model, but this simple tip brought my original airbrush to life
Thanks to your informative video I was able to get my Paasche D500SR back working like new. Thank you so much! Saved me from having to buy a new one, and now I can get back to modeling.
You know guys, it's people like you that make everyone elses lives worth living. I have one of these compressors and now I know how to keep it in tip top condition. The internet would be absolute crap if it wasn't for you guys to show the rest of us how to do things. Many, many thanks for this video and I hope you and your families are safe and well. Great stuff!
Thanks for all the help full info, any chance anyone knows how to lock the motor as my piston arm has come of and can't thread it back on correctly due to motor rotating too.
You sirs, have just saved me a ton of headache. I cannot thank you enough. I just bought a similar type, after two days, the working pressure was just set at 1.5 bars. Disassembled it with your guidance, and turns out the reed valve was just hella bendy. Reversed and put it in place, everything works like a charm. Thank you!!!
Thank you for this wonderful video. It seems the same pump is sold upon many different labels. When my pump was brand new, with the outlet sealed closed with my finger, the pump would hold pressure for about a minute before cycling back on. (About a minute for enough leakage to trigger the switch). I used my new pump for about 10 hours and noticed the minute had shrunk to about 4 seconds. It was pretty much always on. Eliminating any external leaks, I discovered your video. I cleaned out every bit of those hardened, shredded grease-balls and applied a very thin layer of high temp synthetic grease to the cylinder walls. My piston reed valve was also "bent" upward so I made it flat. Upon re-assembly the pump motor would start just fine if the air outlet was kept open, but the motor failed to start with the air outlet blocked. It tried to run but could not turn over with the air pressure above the piston. If I blocked the air outlet with my thumb and then switched on the motor, I could actually control the motor RPM by allowing various amounts of air to escape past my thumb. It was obvious the reed valve needs to be open, it was originally found "bent" open to prevent pressure above the piston from stalling the motor. I made the reed valve barely closed against the piston with minimum closed spring pressure but the problem only marginally improved. So I "bent" the piston reed valve back to approx where it was before and it works perfectly. My theory is the reed valve needs to remain open while the piston moves upward to prevent the motor from stalling when first started, but when the RPM increases then there is enough pressure above it to force it closed. I'm not sure how other people's compressor motors started with a pre-closed piston reed valve. Mine is rated 1/5 horsepower, 1.0 CFM. It's obvious some have... Just a mystery I guess. If someone else has a problem with their motor starting then that reed valve may be stuck closed? Just a thought. I had some minor trouble getting my flexible head rubber valve-disk to seat properly after scrubbing it all clean, but now my pump holds pressure for at least 5 minutes (I got bored and my thumb got sore.. Ha ha) It rapidly pumps up to 60lbs and never lost pressure over that 5 minutes. Thanks again for the great video we need more generous people like yourself to share time, knowledge and experience. God bless. Edit: Tested to hold 60lbs pressure for at least 3 hours. What a huge difference cleaning out that gunk made.
Thanks to your video, I managed to repair my own compressor (like yours, but with a 3 liter tank) myself. Was taking almost 10 minutes to reach 4 bar and start working with it, plus using it at 1 bar.. you'll end up without more reserve air in 5 minutes. A good clean like yours and flipped that copper part too.. and now it's filling less than a minute. Thanks a lot 👍👍
had the same issue with my mini compressor, damn it took this long to find your vid, your vid saved my mini compressor, planning to sell it as scrap now it's running very well again thank you
Thanks for the heads up on this fix guys, my airbrush started doing this today and I was freaking out as my 12month guarantee just ran out so there’s me thinking I’ve to cough up another £70 new but your vid got it back up and running and it even holds the pressure better!
Thank you! Exact video I was looking for, I am used to maintenance on a full sized compressor but didn't know what I could do to help a friends small tankless compressor. Before I took it apart way looking to see if there were any guides on it. She head the same/worse buildup that I cleaned up and re- assembled. Thx! :D
Sorry i domt... But you could make a replacement. find a place that sells engineering supplies. what you need is shim stock, thats what we call it in the UK. Or maybe some thin spring steel....
When You guys ever gonna be in Legnica (Poland) You've got a beer on Me :D. Your vid helped me understand the general rule of compressor work. Mine had 2 silicone valves. The casing had two blank plugs (screw) The one on the back was blocking the intake!!! That was factory made!!! After removing the screw (and cleaning) the time needed for compressor to fill got shorten from ages to about 2 min. BTW Love the Boink sound at 7:00 :D Great timing.
Just took apart compressor a day after following this video to find it had already started to get the bits of rubber clogged up in it again. Order some silicone grease and coated all the seals and the piston head with it. Cycling pressure increased from 30 to 40 psi. Will check to see if it has helped stop the piston seal from perishing after a few uses.
THANK YOU!!! My compressor started acting up 6 months ago. I was ready to buy a new one until I ran into your video. My issue was that my airbrush would spray paint everywhere instead in a clean streak. I opened my compressor and the reed valve was bent up. I flipped it over and now it sprays clean again :) my issue now is that the compressor doesn't keep constantly filling with air when i spray. The compressor will fill with air but once i spray, it won't fill with air again after I stop spraying for a few seconds :/
If you have checked that everything is still clean and not blocked inside the head. Then maybe it is the starter capacitor connected to the motor. On mine it was a black rectangular component with 2 connections. It was mounted inside the rear cover of the motor. I think ebay had some listed.
Great video thanks guys. I have an old one of these compressors that I thought was stuffed, so I'll be digging it out of the garage tomorrow and giving it an overhaul. Cheers!
You want a tank to sit that on Rob, I made one from a big chunk of steel box section, capped off at both ends with a drain plug at the bottom - much smoother spraying when the pressure isn't shooting up and down all the time.
Thanks for this video! I’ve just bought one of these and I love it but it’s left me scratching my head. On the side of the tank it says Nor. Pressure 0-80PSI / Max Pressure 100PSI. I can’t seem to get mine to go above 4 bar on the gauge no matter how much I rotate the top handle, I can get it to go less but not more. I’ve been wondering if I have a blockage or if this is the max these do and it’s working properly? Thank you!
Sounds about right to me. These compressors have a pressure cut off switch. So the pressure will never get above what the pressure switch triggers at. No matter how much you twiddle the regulator, as the regulator doesnt control the pressure switch in any way.
@@Rcmodelgeeks thanks for this, that’s very helpful! I wonder if there’s a way to modify the pressure cut off switch to get an extra half a bar/1 bar without going crazy and breaking something. 🤔 food for thought
Help. Just bought a similar one... it kept pumping approx every 30 seconds. (Checked my hose connections for leaks etc) it still kept pumping every 30 seconds. Now it just won't turn on. Only used it for like 2 minutes. All wires are intact. Any suggestions?
Copious thanks for the info about these compressors. The problem with starting the first time followed by struggling and failure to start on subsequent start cycles were my symptoms as well. The solution was exactly what you taught. My reed valve was significantly bent (crescent moon-like profile - incredible) and the piston seal debris was present as well. It was not the pressure sensor or capacitor as was your experience also. I took extra care to seal all the connections and am ecstatic to get my less than five month old compressor back is service. This problem and its extraordinarily easy solution is unfortunately one of the best kept secrets about these otherwise pretty nice airbrush compressors. Thanks again.
Mine had that same crappy regulator. I added a second regulator that works in tandem with the original,but I can maintain the pressure at any pressure I choose.
My compressor doesn't turn off its always running and max pressure before using airbrush is 50 psi and then drops to 20 psi when using brush...any advise chaps?
DO NOT FLIP THE "BENT" VENTILATION PAD. the bend is there on purpose. aside of letting air into the cylinder it is intended to work like an unloader valve to release pressure right above the piston once the pressure switch cuts the motor. by turning it over the pressure gets "stuck" on the piston, which can cause problems with restarting the motor because it takes more energy to get it going again. symptoms are a stuttering motor or lack motor restart until 0psi is reached. it often makes your compressor sound like it's struggling for air as well. without a tank, like on this model, pressure is actually stored right above the metal plate beyond the check-valve. otherwise the separation wouldn't be necessary.
Very interesting read! I was wondering if you could maybe give an opinion on mine then before I take it apart don't want to do this if your not supposed to! Mine it's like it's got a slow leak but not able to find it its kicking in every minute and recharging itself like its its loosing pressure but the regulator needles not moving down like it's losing any? Its spraying fine no probably there but pretty sure it never used to do this! It's only 4 month old if that so can't see it being clogged with shit! I just don't know it like you say the aur is stored up on the piston in single tanks and it's just losing slight psi or what but the needle certainly isn't moving to show it dropping psi!? Just not sure if this is normal
My piston "ring" is bad, I wonder if there's a replacement out there? I've searched and nothing. A MAJOR component and no replacement parts available?!
I've got a AS-189 compressor, it's the same single-piston powered compressor with a 3L tank connected to it for providing continuous airflow, however it takes hell of a lot time to fill the tank (3-4 minutes) and even with the usage around 15-20 psi, it quickly starts to refill the tank again and in a short time (10-15 minutes) due to repetitive stop & runs, compressor works so much and gets hot. Is it possible for me to disconnect the tank and use it just like this ? What kind of connections shall i made to achieve it ?
Just bought a good compressor but not sure if it's fault is fixable , i get about 2 minutes of air spray and then if auto shuts off due to being super hot, help much appreciated
RC Model Geeks. I could tell you what to do when one of these airbrush presses overheats, which could be the case that I have to look at, because I think it is an electrical problem, of course, the compressor works normally but is very hot. I don't want to use it like that. It might be normal for it to heat up. It has an engine with four pistons. Tnx.
I've got a similar one. I was hoping to be able to add some fittings to use it as a vacuum pump too, but it looks like that won't be possible, given that the air intake is through the piston. But thanks for the vid.
Dunno if you guys gives a shit but if you are bored like me during the covid times you can watch all of the latest movies on instaflixxer. I've been streaming with my girlfriend during the lockdown :)
Hi, nice video, I have one with two pistons but one of my silicone umbrella valve has broken, where can I buy one if you know? pretty much on alibaba but i don't know which one. thanks
BETTER LATE THAN NEVER AND AS USUAL NO SUPPORT FROM THESE DUMB COMPANIES. 2 MONTHS OLD MAYBE AT THE MOST ALL TOGETHER 3 HOURS WORK ON IT. JUST DIED. THANKS TO YOU I HAD THE LUCK FINDING YOUR VIDEO BEFORE I SENT IT IN. SAVED ALOT OF HASSLES MUCH OBLIGED OLD CHAP. NOW I KNOW MY COMPRESSOR AS A ADDED BONUS. THANK YOU TAKE CARE AND HAPPY DAYS. SOUTH AFRICA
Thanks for posting this!! I use an Iwata Ninja Jet for work on a daily basic, and i find that after 9 months or so it starts to take AGES to get up to pressure. I've just bought replacements in the past, but thankfully i've kept the old ones. I'm hoping to have a look at them at the weekend following the advice on your video. Has anyone successfully done the same on one of these? I'm hoping it will be as straight forward as it is on this type of compressor .
@@Rcmodelgeeks I used to use one similar to the one you repair in the video, but found the Iwata fit's in my toolbox better...lol. It does have a hard life though, the poor thing! I'll let you know how i go! Thanks again..
@@Rcmodelgeeks Well, i had a look this evening and although the inside of the compressor was really dusty, the seals and everything in between were actually really clean :( I put it back together and it's still the same. Is there anything else to check? Also, would you mind if i joined your Facebook group to ask if anyone else might have a solution? I hate chucking stuff away and reckon there's got to be an answer!
That's assuming the person has at least average mechanical skills, they can take something apart and put it back together again. Some people are klutz's on anything mechanical, I had a relative that had a masters degree in engineering, he couldn't assemble a bicycle he got at Wal Mart, I had to take it apart and reassemble it for him to save his son's Christmas. He was almost a genius on designing something on paper, but couldn't do anything with tools.
No point knowing the theory if you cant put it into practice! Its very common, seen it many times with university grads. Know it all but cant use the tools to put it into practice ;o)
If your in a place with high humidity this is normal, Its the same with all airtools. The solution is to use a inline dryer, either a moisture trap or desiccant tube. (either you can pick up on amazon for less than 10 bucks) Your local hardware store might also carry much larger versions of these. But you know the sad part is you can buy a 3 gallon compressor (while loud as hell) for 70% less, and the thing would probably store enough air to run 10+ mins at constant pressure without having to kick the compressor.
Thought it was gonna help me but nope still can’t use mine. Brand new too never been used. I’m going to just scrap it and throw it away. IF ANY KNOW WEBSITES WHERE I CAN GET A WORKING ONE DROP BELOW THANKS.
I got mine from harbor freight. It's a cheap Chinese air pump,but works great. Until you watch it jump off onto the floor and the main oulet pipe breaks. Well, mine did. It vibrated right off the stand and landed on the gauges. Lucky they didn't break. I had to heat the stump with a mini butane torch and had to buy a very big easy out to remove the broken pipe. The whole kit,airbrush and pump was $80 or more. The brush works fine, I added a dryer and had to add an additional regulator because the original wouldn't go low enough. I was able to find the correct size fitting that broke. It's interesting that was full of powdered stuff. Glad it works good now. Want to sell it?
I recently bought a compressor, it came with a cheap airbrush, been working fine till the other day, now, every time I turn on my compressor, it starts, but then cuts out virtually straight away. I only bought it about two months ago, brand new. Any ideas guys?
the part that is missing is the "bleed valve" which is needed to bleed off excess air because these compressors have no storage tank and therefore NO PRESSURE RELEASE VALVE this requires the bleed valve to allow any excess air to bleed off ONCE you set the operating pressure required to airbrush hope this helps anybody who has the bleed valve fitted the result will be a continuous operation of the compressor with the bleed valve letting excess air escape through the valve
I have the same exact set up, So glad you have this out, I had the same trouble, but before I found this video, another forum had me take the pressure switch out of the head, incorrectly, so I'm high & dry until I get another pressure switch.

BETTER LATE THAN NEVER AND AS USUAL NO SUPPORT FROM THESE DUMB COMPANIES. 2 MONTHS OLD MAYBE AT THE MOST ALL TOGETHER 3 HOURS WORK ON IT. JUST DIED. THANKS TO YOU I HAD THE LUCK FINDING YOUR VIDEO BEFORE I SENT IT IN. SAVED ALOT OF HASSLES MUCH OBLIGED OLD CHAP. NOW I KNOW MY COMPRESSOR AS A ADDED BONUS. THANK YOU TAKE CARE AND HAPPY DAYS. SOUTH AFRICA
Great news! Glad you have it fixed ;o)
Love watching you guys, learn allot but go on change that jumper
this vid helped me fix mine, and yes, it was the reed plate.
Awesome
Thanks for posting this!! I use an Iwata Ninja Jet for work on a daily basic, and i find that after 9 months or so it starts to take AGES to get up to pressure. I've just bought replacements in the past, but thankfully i've kept the old ones. I'm hoping to have a look at them at the weekend following the advice on your video. Has anyone successfully done the same on one of these? I'm hoping it will be as straight forward as it is on this type of compressor .
Good luck with fixing your Iwata. I expect the issue will be simple. Make sure to check the one way valves for correct sealing.
@@Rcmodelgeeks I used to use one similar to the one you repair in the video, but found the Iwata fit's in my toolbox better...lol. It does have a hard life though, the poor thing! I'll let you know how i go! Thanks again..
@@Rcmodelgeeks Well, i had a look this evening and although the inside of the compressor was really dusty, the seals and everything in between were actually really clean :( I put it back together and it's still the same. Is there anything else to check? Also, would you mind if i joined your Facebook group to ask if anyone else might have a solution? I hate chucking stuff away and reckon there's got to be an answer!
@@DJNee sure no problem
Please help me my compressor wont turn off by it self and it passes the 150 psi.
That's assuming the person has at least average mechanical skills, they can take something apart and put it back together again. Some people are klutz's on anything mechanical, I had a relative that had a masters degree in engineering, he couldn't assemble a bicycle he got at Wal Mart, I had to take it apart and reassemble it for him to save his son's Christmas. He was almost a genius on designing something on paper, but couldn't do anything with tools.
No point knowing the theory if you cant put it into practice! Its very common, seen it many times with university grads. Know it all but cant use the tools to put it into practice ;o)
I think i have the exact same compressor.
Water is spurting out of the hose, can ruining the finish on my models.
Can you offer any tips ?
If your in a place with high humidity this is normal, Its the same with all airtools. The solution is to use a inline dryer, either a moisture trap or desiccant tube. (either you can pick up on amazon for less than 10 bucks) Your local hardware store might also carry much larger versions of these. But you know the sad part is you can buy a 3 gallon compressor (while loud as hell) for 70% less, and the thing would probably store enough air to run 10+ mins at constant pressure without having to kick the compressor.
Thought it was gonna help me but nope still can’t use mine. Brand new too never been used. I’m going to just scrap it and throw it away. IF ANY KNOW WEBSITES WHERE I CAN GET A WORKING ONE DROP BELOW THANKS.
I got mine from harbor freight. It's a cheap Chinese air pump,but works great. Until you watch it jump off onto the floor and the main oulet pipe breaks. Well, mine did. It vibrated right off the stand and landed on the gauges. Lucky they didn't break. I had to heat the stump with a mini butane torch and had to buy a very big easy out to remove the broken pipe. The whole kit,airbrush and pump was $80 or more. The brush works fine, I added a dryer and had to add an additional regulator because the original wouldn't go low enough. I was able to find the correct size fitting that broke. It's interesting that was full of powdered stuff. Glad it works good now. Want to sell it?
Thanks!! I did exactly what you did and fixed my issue.
Awesome.
I recently bought a compressor, it came with a cheap airbrush, been working fine till the other day, now, every time I turn on my compressor, it starts, but then cuts out virtually straight away. I only bought it about two months ago, brand new. Any ideas guys?
This guy sounds like Richard Ayoade... 😂😂
thanks sir very much it saved me trip to repair shopš, and enterteining as well
glad to hear it
the part that is missing is the "bleed valve" which is needed to bleed off excess air because these compressors have no storage tank and therefore NO PRESSURE RELEASE VALVE this requires the bleed valve to allow any excess air to bleed off ONCE you set the operating pressure required to airbrush hope this helps anybody who has the bleed valve fitted the result will be a continuous operation of the compressor with the bleed valve letting excess air escape through the valve
