• Central Pneumatic 21 G...
The main upgrade I did was install a new and bigger regulator. Along with the regulator, a matching inline air filter was installed before it in the attempt to reduce the moisture and debris from getting into the hose and tools. Simple upgrades like this will hopefully improve performance. Still working out the air filter. I should have a solution soon and will share.
Hope you enjoy and thank you for watching!

Hi 007 my name is Bob Ray. My wife just got me this compressor as an early Valentine's Day gift. I have been an automotive technician for 34 years and a wood worker for about 2.I will be using this in my wood shop and to finally be able to use air tools when I do maint. and repairs on the family cars at home. But anyway I just wanted to thank you for taking your time to make and post these videos. You have really helped me stop a possible disaster with the shavings in the oil. Also to be able to see what is to be expected when you pull the drain plug for the first time is something a manual could never get across as clearly. I can tell you are the type of person who likes to do thing right and be thorough in their work and I have a huge amount of respect for you. So again I thank you and I hope you and your family had a great holiday. Peace.
I appreciate the kind words. Thank you.
I got the same compressor, I replaced the reed valves, cold start valve, the capacitor, check valve.
To surpress the sound what I did is. Attach a hose with a fitting, take the filter off get a fitting attach a hose to it that leads to outside. Done ...simple cheap and works. I also will draw air from outside the workspace which is colder cooling the head a bit better.
Hi Michel. I have this compressor also. What does replacing reed valves, cold start valve, the capacitor, check valve do for your comp.? I'm looking looking to do some upgrades on mine.
Did replacing all that stuff help the compressor keep up with your tools?
Interesting
I think I'll be getting one of these compressors soon. Just a couple of ?s. Did you ever try the oil filter/air filter mod? Have you done any spray painting with this? If yes, what gun did you use? I've heard some folks complain about the noise. Did changing the filter help? Have a rubber hose to a filter mounted elsewhere? Is the HF 29 gal worth double the price? Thanks... BTW...Good video.
Yes, I am trying out using an oil filter as an air filter, don't see much of a difference in noise or air intake. Have a plan to do a video on this and some other options, however not sure when I'll get to it sure to my fulltime job... I recently used the compressor for painting a few filing cabinets. Used the cheap harbor freight gun. Did well, but would not use this unit for large projects. Paint small portions and let it rest, if you don't, the compressor will run constantly, heat the air and allow too much moisture into the lines even with a moisture separator used. It is noisy so either sit the compressor a decent distance away from you or wear hearing protection.
Hey, that's an awesome idea for hanging the filter/ regulator there! Did you have to drill the holes in the mounting things, or did you find some that just worked? And what are those mounting things called? (Don't even know how to start looking for those, I'm new to DIYing stuff)
+ElectroPulse those are homemade brackets. I bent them out of some bar stock from the local hardware store. Drilled the holes to match the holes for the screws that hold the handle on the tank.
Hmm... interesting. I might need to finally get me a vise so I can do that as well. (I ended up ordering a used reg/filter setup, similar to yours, on eBay after seeing your mounting solution :) ) Thanks for the idea!
I saw video where a guy ran piping out thru the wall of his basement and made a huge drop in noise.
Links for your set up
Hi there, I am very curious as to what brackets you used to mount everything to the handle? Did you fabricate it yourself? If so, what material did you use? Last question, what type of connectors did you use? I appreciate both videos you did of the Harbor Freight compressor. I'm not that experienced with the larger compressors so this was a huge help!!
The brackets I fabricated out of some cheap bar stock from the local hardware store. the fittings were from the black iron pipe section from same hardware store. Since the regulator is a 1/2" setup I needed to step up from the leadout hose which was 3/8"npt coming from the tank, then step back down to the 3/8" hose I was using. the Filter regulator unit I am using is way overkill for this application. You can get by with a smaller 3/8" setup and everything will run just fine.
@@jungleking007Channel Thanks so much for all of your help! Great video!!
So, it's been three years since you posted this I was just wondering on your thoughts and opinions on the Lincoln Industrial filter and regulator?
There's no reviews or video's anywhere that I could find! I have the same exact compressor as you and just looking for a good quality filter and regulator for my setup. There seems to be only a few places that even sell it for high dollar compared to some others on Amazon that I'm not 100% sold on.
Awesome informative video by the way! 👍💯💥
Works great! I have had no issues with it at all. Used at least once a week to blow off dust, air up tires, or the occasional need for the pneumatic impact. This filter and regulator setup is more an industrial part. Might have to check with some industrial supply stores to see what they have. Some auto parts store may be able to get them too. It's most likely overkill for such a small compressor. There are also filter/regulator all-in-one combo units that function the same, but a little more compact. The one you see here came off a work bench I won at auction a while back. Thanks for watching!
@@jungleking007Channel Thank you for the reply! I just purchased the same filter regulator that you have today. I'm going to set mine up just like your but mount mine up on the wall. Now time to buy 1/2" shut off valve and a short hose and fittings which is kind of a pain going from 1/4 to 1/2 and then back in reverse to hook up airline while not trying to have restrictions. I was trying to look at your video to see what fittings you had and hose that I'm assuming was 3/8 with 3/8 thread or 1/4. I was going to use a reducer but it would restrict to im tossing are the setup to have the most are flow like your setup.
Great video, i am an amateur and would like to know if you have a suggested parts so i can purchase what i need at the parts store, for the upgrade; also looking forward to the air filter upgrade as soon as you get it posted. Thanks for all you do.
There are many brands of filters and regulators out on the market you can choose from. The moisture separator and regulator assembly I am using here is more of a heavy duty industrial unit, bit overkill but it does the job. I'll post a parts list in the description shortly.
I like your setup. Where did you get your 3ft hose from?
Harbor freight has them. Usually called a feedline, jumper hose, or lead in hose.
Ok thanks
Do you have parts list for the mods you did?
Does the order of the water trap and pressure regulator matter should one receive the air before the other
Filter first, then the regulator is the recommendation. Air from the compressor will hit the filter first to remove the moisture and debris, then pass through the regulator. If it were the other way around all the moisture and debris would clog up the regulator.
@@jungleking007Channel 9.
Hey, first thanks for the video. I just got this compressor 2 days ago, because this kid in my neighborhood needed money for prom and offered to sell it to me for $35.00. I don't usually buy power tools from Harbor Freight, but I couldn't pass up that kind of deal. So my question is when I first changed the oil it was a thick milk looking color. (He did say it had been sitting in the garage for a while). So what would be the best way to flush, and clean to make sure I get the best performance out of it with the longest amount of life?
+justfoundnemo sounds like moisture may have gotten into the oil. If it were me cleaning it out with that issue, I would most likely take the side crankcase plate off and rising out with mineral spirits. Then I would fill with oil and run the compressor for a couple minutes. After, drain the oil and fill again, and perform the same procedure until the oil is clear. This should hopefully relubricate all components and break up any debris that shouldn't be there. Good luck! How this helps.
How is the update coming on the tank, can it handle a 1/2 air impact with out it kicking on all the time, Would love to see a video on that.
It's on the list as I'm curious myself. Unfortunately, life has gotten in the way at the moment, and the purchase of some tools has to wait. Soon though... I will get it done.
u can do 2 tires before it comes on
I use a 1/2 impact all the time this compressor is suitable to run it . I never had an issue. They run of 90psi which is no problem for this compressor
I have that compressor and a 3/8 impact from Central Pneumatic it peter's out real fast and the compressor always needs to fill again have you found a solution? This is basically an oversized tire pump unless I can get it to run my tools.
Bian - Like they used to say in car racing, there is no replacement for displacement. A 60 or 80 gallon tank is best but you CAN run most air tools with a 20 or 30 gallon tank. It will just kick on more often. Or as we older guys say - more breaks for us.
A couple things will help your flow - and flow is the key word. Transition as much as you can to 3/8" diameter hose and piping and go to high flow quick connect fittings. Only used those coiled hoses for air nailers and blow guns. ONLY use at least 3/8" hose... and ONLY use 3/8" valves. The high flow fittings are a dramatic difference. As for PSI, yes your 1/2" impact is designed to run on a working flow of 90psi. But if you set your regulator to 90psi and then pull the trigger on your impact, a pressure gauge at the impact (while its running) will show your "running" or working air flow at the tool is probably around 50psi. You can see for yourself on RUclips videos and make your own inexpensive pressure gauge testing fixture to measure what works and what does not.
You need that flowing pressure at 90psi at the tool - NOT 90 psi STANDING STILL AT THE REGULATOR - to make the impact work at its best.
So to do that, open up all your "plumbing" to let the air flow better and set the regulator at 110-120, and you will find you now have 90psi at the tool while the trigger is pulled, so it can work as designed.
I bought the next size up (26 gallon) and have a LOT of moisture coming out of my line despite trying several things. I did some research and found out that the hot air coming out of the compressor needs to cool sufficiently and the water needs to be filtered before hitting your line. That's why people run piping with water traps coming out of their compressors before their air hoses. Actually, it would be ideal to catch the air coming straight out of the compressor and cool/filter it before going into the tank (kind of like this ruclips.net/video/SA7yj1EXDZU/видео.html but with the radiator and filter lower than the compressor). I'm in the process of trying to decide how to modify my compressor to remove the moisture so I can HVLP spray paint my car. I might just try to get by with a simple PVC post tank pipe line with 2 water traps, hook my filter to the air output of the endpoint and use filters before my tools for now. I don't know if I need a permanent solution. I'm just trying to avoid spending 4-5k on painting my car.
That inlet system may trap a Little moisture but it still won't address the condensate formed in the tank after the air cools a bit. You are still going to need a filter system on the outlet. If this is primarily going to be for painting, try looking for a large In line desiccant filter. Don't use PVC pipe anywhere in an air system. Too dangerous. Use black iron pipe, or what I have considered was the Maxline RapidAir system.
you should use an oil filter the threads going in are three 3/4 inch ntp what you need to do is get a bushing they make great air filters for air compressors
+austin eguires never heard of this before, but sounds like a brilliant concept! Might include this as an option when I do some testing. Thanks for the idea!
JungleKing007 If you try that oil filter on the intake idea, you should take some precautions because not all oil filters perform the same. Install a T fitting between the filter and the compressor head. Put a vacuum gauge on 1 of the legs. Check vacuum draw with the original filter first, then with the oil filter. Use whichever one draws the least amount of vacuum and remove the T.
the bolts that are screw onto the tanks or bullets waiting to shoot out..
i wouldn't do that bud...
+Fghj GHJjj Those are the bolts that hold the handle on the tank. No drilling was done to mount the filter and regulator. Utilized what was already there.
Dumbass
You clearly did not watch the video where he clearly says "I used the holes where the handle was"
Sweet comment dumb ass.
