If you have a Central Pneumatic air compressor, and you didn’t buy it used, from a garage sale, or from on on-line end-of-line wholesaler, odds are pretty good that you bought it at Harbor Freight.
In 2017, Harbor Freight offers about 35 different Central Pneumatic air compressors, from a 1/6 HP air brush style to a 5 HP, almost commercial type, on a 60 gallon air tank. They even have one model of a gas-powered, wheelbarrow style, that is quite well priced.
Central Pneumatic air compressors can be purchased through Harbor Freight on-line, or at the many Harbor Freight stores found throughout the United States.
Buyers of Central Pneumatic air compressors are, pretty much I think, aware that you get what you pay for. This line of compressors is entry level. I don’t believe they are made for serious compressed air use, where whether or not a compressor works means that trades persons do or don’t do work that day.
Which is not to say, if you are a periodic user of compressed air – the typical small workshop or home garage for example – you won’t be happy with this brand of compressors reliability. I just wouldn’t put the supply of my plants air system at the mercy of this particular brand.
While Harbor Freight boasts of having manufacturing around the world, I would be surprised if they actually owned a factory that makes air compressors. Their entire line is similar or identical to compressors of other brands with different colors and different labels. I could be wrong and will be happy to indicate so if someone can provide proof that HF actually makes their own compressors.
Regardless of whether they make them or not, try to find parts for a Central Pneumatic air compressor. Aside from pressure switches, gauges, regulators, PRV’s and check valves (all the same as those found on many other brands) there are very few repair parts for the compressor pump or the motor. Parts from other Central Pneumatic air compressors can often be used on other models of this brand. If you can scrounge or buy a non-working compressor, some parts from the old can be reused to fix others that have failed. Depends on your skill level as to whether or not this works for you.
If you are having a problem with your Central Pneumatic air compressor why not add a question or comment here? Include the model number of your compressor. As a result, perhaps the Central Pneumatic air compressor owner/user family, which is a huge one, can offer advice as some of them will, undoubtedly, already dealt with the same problem you are experiencing with your HF Central Pneumatic air compressor.
I have a 9gal wheelbarrow type and it suddenly started shutting down once it reached top pressure instead of throttling back to idle and cycling on and off. Found the pilot valve shaft was slightly bent and replaced that, but it is still shutting down. I’m now wondering if it’s something to do with the throttle control.
Bought a 1/3 HP hot dog compressor Central neumatic from HF store used 6 times to fill pool toys and my car tire; Now it does not build pressure, never again will I get Peumatic Comp again ; I guess you really get what you pay for.
trying to find a replacement tube, the one from motor to tank that has compression ring on either end. mine sheared off after I attempted to tighten the nut. what kind of store sells aluminum or better yet copper flexible tube and compression rings? 3gal 100psi pancake
The air outlet that attaches to the hose broke off
Thanks

My grandfather recently bought a 2.5 HP 21 Gallon compressor and forgot to put the oil in for initial use seizing the compressor. I since then have gotten the compressor running although it will only occasionally build pressure, and even then it only gets to about 20 PSI. I took the top of the cylinder off and the small metal plates now refuse to stay in place. Is there something else I need to do to get it back working or should I just replace the compressor with another that I have?
I have the 21 gallon CP 2.5 HP model 61454. I recently replaced/repaired the reed valve and was working fairly well. Then a couple days later I noticed it kept running and would not go past 90 psi. Someone told me it might be the pressure sensor, but want another opinion form someone that may know from experience. Also if it is the pressure sensor or something else, where can I buy the right part?
I have a friend who has a Central Pneumatic Model# 95386 air compressor.
It is having and intermittant problem of the reset switch operating and having to be reset to get it started. When it starts again, it runs very slowly until it eventually trips again.
Sometimes it will run normally and stay running at the normal higher rate of speed and then eventually return to the slow speed until it is stopped by whatever it is that is tripping the reset. Any ideas as to which direction to look to solve this problem?
Where can I get a regulator assy for a Central Pneumatic 95275 compressor?
I have a problem with a central pneumatic (Harbor Freight) 29 gal oil lubed unit that will build pressure fine until it reaches ~100 psi then it starts to “strain”/”lugs” and motor ( single phase induction 120v) begins making some “ticking/clicking” noises and unless I turn it off manually it will trip the breaker in the panel ( never the motor reset).
I’ve replaced the run cap-(did not fix). Tank check valve seems ok ( no visible signs to indicate faulty and no air leaks from anywhere when tank pressurized).
Unit is supposed to cut out at 150 and back in at 120.
I purchased the unit in this condition (used- barely-it looks brand new so obviously hasn’t seen much use and seller didn’t have much history about it). What else could it be? Thanks in advance.
Had my 125psi 2.5 hp 21 gallon central pneumatic lil over a year NEVER BEEN HAPPY DOESNT NEAR ENOUGH AIR. Also the cold start valve went out as they ALL DO !
Went to replace it and never got valve screwed all the way in until the housing on the compressor snapped into. BEFORE YOU SAY I OVER TIGHTENED, I’M A CERTIFIED PRECISION STEAM TURBINE MECHANIC I KNOW ALL ABOUT TORQUE SPECS AND EXCETRA.
TERRIBLE PRODUCT WILL ( NEVER BUY ANOTHER ONE ! JUST SCRAP NOW!!

I purchased a Central Pneumatic 67696 Air Compressor several years ago. A few weeks ago it would not shut off at the high pressure level approximately 150PSI. The PVR goes off and the motor does not shut down. I ordered a new switch thru Amazon. It arrived yesterday after a week delay and got it installed. Nothing has changed. Any suggestions.
I bought a central phumatic twin cylinder 145 psi pump 1 year ago with a new 5 HP electric motor 3450 rpm. I did the math from the HF manual and installed 4.5″ pulley on electric motor. I just started to build the air compressor a week ago June 10,2020 the parts have been in my garage shrink wraped until I needed them . After several configurations of the 3/4″ tubing that i replaced from flared copper to compression stainless steel and installing new tank check valve 3/4″ with a a 90-145 psi pressure switch all I can get out of my compressor is 25 psi. I have a HD 60 gallon tank. The pump gets close to 25 psi and slows to trip the electric motor if I dont throw the on off switch. I have changed the start capacitor and run assist capacitor with no change. Checked the reed valves were all good and put new gaskets on the valve plate and head.i changed out 2 different pressure switches and 2 capacitors. I am out out ideas and watched videos asked people at HP and everone tells me to change the parts I have changed please can some one help me .
I have a 3 gal oiless pancake compressor. Central pneumatic. I am looking for the regulator for this compressor model 60637. Any help.
I have model E 99780. It runs and builds pressure but does not hold pressure. New hose and fittings. Still does not hold for very long. And it is taking along time to build pressure.
I have the 21 gal model 61454. Less than 2 months old. The reset keeps popping when its time to fill ? Start of day. Motor not hot. Tries to start then pops? Any ideas?
Where is the shaft cap and centrifugal switch on this if there is either? Also where would I get the same motor or one that works better yet is compatible to this compressor

Hey there. I got the 69091 model 21 gal 125 psi air compressor. I let it sit outside forgetting it was there and didn’t change the oil. I ran it for about a year here and there doing small stuff but this week I turned it on and heard a snap and the motor went to running super smoothe. The connecting rod broke.
I need to know if there is a replacement part for it and if so a part number. I can’t find one. I’ve emailed hf and no answer yet. I’d like to fix it if it’s available. Its been a great small compressor. Thanks for your input
I bought a compressor used and doesn’t have a manual. How do i find a model number. Can you help

Hi I have a HF 62551 (many model number are the same) compressor 6 gal, 1.5hp . I need regulator parts or a regulator. Is it available or can you recommend a generic I can get a few parts out of. Parts and orings just under the knob. Thanks
I have a 3 gallon pancake compressor and pulled a Griswold. I stepped on the manifold coking to the tool side of the regulator and the manifold is broken in two places. Any suggestions for where I can purchase a new manifold that would fit? Compressor, gauges and regulator all work great. Thanks
Just bought a 21 gallon compressor and was wondering if there was supposed to be metal stuff in oil breather
I have a CP 21 gal 125psi vertical A/C! It will not build pressure above 25psi & the Start valve is continuously leaking! Is there a way I can repair it or must I purchase a new start valve! I live in South Louisiana!

I have the 8 gallon Central Pneumatic model 40400, I have an issue where the shut off switch won’t stay up by itself in order to shut it off while running. I have to keep it held up while I pull the plug. It will stay up when the compressor is not running. I’m guessing I need to just replace the switch, Anything else I should check before doing that?
CP 2.5hp 21gal, After good service for 3 years, the 1/4″ cold start valve failed to close after running the normal time. I ordered another cold start valve and installed it and it also bypasses continuously without closing. Am I missing something obvious?
I have a used Central Pneumatic “67708” air compressor and last summer the Oil Breather Plug just shot out. I contacted Harbor Freight and they don’t sell them. So my questions is will these fit my air compressor?
I have a 21 gal Central Pneumatic compressor… Works great — fills up to 105psi and as soon as it hits that number, it shuts off and starts bleeding air from the pressure valve. When down to 50psi or so it starts up again. Back up to 105psi, shuts off and bleeds very rapidly down to 50psi and starts running again. I just replaced the pressure valve with a like one — seems to be doing the same thing. Ideas?
Item #67696 Won’t hold air pressure at all wont stop running
I have the Central Pneumatic #62511 6 gallon oilless air compressor that pumps up to nearly 150 psi but does not stop. I attempted to remove the top, but none of the sockets I have will remove the m6x25 screws (I have tried all metric and sae sizes that will fit down the hole. It looks to me like the screws have a round head rather than a hex head which makes no sense, except if this is a way to keep owners from servicing their unit. The compressor is about a year old, and has about 5 hours of use on it. Any information on this will be welcome.
My Harbor Freight air compressor has only about five hours on it, and it will not pump more than 50 PSI. Used to work fine.
Model 62803, 21 gallon, 2.5 HP motor. Can you advise?
My 6 gal 1.5 GO will not start its approx 8 months old barely used shot approx 400 3 in nails that’s it.

My central pneumatic compressor 2.5hp. 21 gallon squires oil through the fill cap?? What can it be??
I have a 30 gal 150 psi vertical compressor that won’t pump up more than 50 lbs. No leaks. Where can i buy parts to rebuild the motor? Compression rings and oil rings and gaskets.
Can the Central Pneumatic 3 gallon 1/3 HP 100 PSI Oil-Free Pancake compressor be modified to have an intake feed rather than pulling from the ambient air around the motor, without having to drill and tap the cylinder head for a check valve and somehow disabling the intake through the piston?
I have a central pneumatic 3 gal 100 psi. It wont cut off after reaching pressure.
Hi, I have a central Pneumatic 1/3 hp 3 gallon pancake compressor, it won’t work at all. My husband used it for some trim and now it’s completely dead. Tried the reset switch and got nothing. Is all hope lost? Thank you
I have a Central Pneumatic model # 61454
The problem I am having is it shuts off at about 40 lbs and it won’t come bass look on unless I hit the reset button. Anyone else had this problem?
Brand new 1/3hp 3gal burns up fuse as soon as it is turned on. What amp fuse do I need?
father has a CentralPneumatic 2.5 HP, 21 gallon, 125 PSI cast iron vertical air compressor model 67847 that will not start. Can I get some ideas on what to troubleshoot that could be the problem for this compressor. My dad does have the original manual and I called the customer service number but they were not very helpful. Tried taking to a repair shop and were informed they do not work on Harbor Freight compressors
Hi,
I have a 3gal oiless 100psi pancake compressor Model # 61615. it was filling today and then suddenly I heard a big change in the noise it was making to fill. I then noticed it would not fill at all. I took apart and discovered the aluminum line that goes from motor/pressure head is broken. Any chance in finding a new one?
I have the average 10gal 2.5 hp air compressor on wheels pushes like 4cfm. I would like info on how or if possible to install proper compressor to get like 7.5+cfm I see motors and compressor for under 200 total but no info on if it will fit my style
I purchased the 1.5 HP, 6 GAL. 150 Max. PSI. compressor. I used this about 4 times. The 5th time, I noticed that the compressor ran for a longer time than normal.
I went to inspect, found that the pressure gauges both showed less than 10 psi. I could feel the air being by-passed out the relief valve.
So I took off the top and checked the fasteners for the head. WOW, found two of them stripped. CHEAP FASTENERS FOR A $100.00 plus compressor.
Will never buy another central pneumatic item!!! I will go to Home Depot and get some higher grade fasteners. Thanks Central Pneumatic.
My start valve on my 125 psi harbor freight compressor wasn’t popping out. I replaced it. Still didn’t work. After checking things I found on the internet about it, plus taking the head off and checking reed valves, it still wouldn’t work.. I removed the air filter and the start valve popped out and started filling with air.
I replaced the whole filter unit.. Works great!
I have model #69667 I need replacement part 49 drain valve broken ?
Anybody know where I can get the three-eared Inlet valve reed for a Central Pneumatic 26 gal air compressor?? (item #69669, part #6 in the PDF owner’s manual) Thank you in advance
I have a older central neumatic air compressor model 61693 21 gal 2.5 hp I need a connecting rod where can I get one
I have a central pneumatic model 61454. It is a couple of years old. About 2 weeks ago, I noticed that it would not pressurize past 75 psi.. It then dropped to max of 50 psi a week later, and now it won’t go past 25 psi. Any suggestions?
I have a central pneumatic compressor model 69667. Do these compressors have a serial number on them or is it just the model number?
I have 21 gallon compressor. Does not build up pressure into tank. Pressure directly out of crankcase. What do you think problem can be???
My father purchased brand new from Harbor Freight item 69269 a 3 gallon 1/3 HP Central Pneumatic oiless air compressor in August 2017. He has used it maybe a half dozen times in 2 years. 2 weeks ago it was used to put air in golf cart tires and it worked fine. 3 days ago turned it on and it will not build air pressure. Neither air gauge (tank or outlet) is registering any pressure. If I pull the relief valve there is air pressure. Also air is released when the drain valve is opened. There is no pressure using the air hose and attachment.
Is this fixable?
My 2.5 gallon, unused but 2 years old, builds pressure to 100 psi but will only give a short weak burst of air through my air gun. Tried other tools with same weak response.
I have a central Pneumatic oil less airbrush compressor model 60329.
I am in need of a pressure switch and I called for a replacement and was told they do not make replacement parts for this compressor. Does anyone know of a compatible pressure switch for this model?
Thank you
Thank you since I already have the gauges and I just would put together a manifold would I just need the regulator without the gauge.
Thank you for your information, I have 60730 and the cast manifold cracked, of course not wanting to add to landfill what parts could you direct me to to make my own manifold. I am sure I can get the brass fittings and I have the gauges, just the regulator piece to control pressure would have to be added can you assist me on finding the right one?
3gallon model 60637 plugged in one time blew fuse and plug a gfi socket , and now cant find fuse, why is this happening , bad batch or what
Hi I have central pneumatic 2.5hp 21gal model 62803 and need help finding the uploader tube number 55 in the manual. I’ve been to several places that sell compressor parts and was told that harbor freight does not share information about their products. I also checked with a couple of harbor freight to see if can get a part number or someone point me in the right direction and no one could.
Hi.
I have a 2 hp 4 gallon (60567) compressor from Central Pneumatic.
Motor was stopping at lower and lower pressure and would restart itself again sometimes after 2 minutes on 0 bar. No breaker would jump or anything else.
Sometimes it would pump to 6 bar, sometimes to 2,5.
Expected Pressure switch failure, replaced with new one.
No difference yet. Seems the pressure switch works and gives power to the motor.
Breaker switch does not jump, no reset needed but the motor just has a mind of his own.
What to do?
Cannot find oil plug replacement nor the size. Need assistance in replacing the plug.
I have a 21 Gal 2.5 HP 125 PSI compressor (model 61454) I bought about 5 years ago. I need to get a replacement Cylinder Gasket (part 16 from the manual). Any idea where I can get one?
I just purchased the 61454 CentralPneumtic compressor today from Harbor Freight. I followed al of the instructions making sure that oil level was proper. Initially the compressor would not start at all. After a few more attempts it would run for about 15 to 20 seconds then trip a breaker. I guess there is no factory acceptance testing done on these all. I will be taking this back tomorrow for refund and Not a replacement. I am very, very disappointed by the lack of acceptance testing is a thing of the past of I guess for this product as well as about everything else.
I just bought a 21 gal 125psi upright central Pneumatic compressor at a Harbor Freight parking lot sale. It runs fine but wouldn’t build pressure over 40 psi. I checked the reed valves and one was broken. I order a new set and in the process of fixing it I broke the exhaust tube. Any idea where one could be bought from? Would it be worth it to try to fix it or just carry it back, I still have a couple of days to bring it back. I got it real cheap and I’m kinda thinking to just try to fix it. I will use it for air tools but not very often, just to work on my own cars some.
Hello i have a 2.5 hp 10 gal 125 psi central Pneumatic compressor , when i run it it runs for a minute then kicks off , even with valve open , i bypassed the reset and it ran fine and filked up to 125 psi , i then shut it off worried it woukd blow up lol Could i just need a new reset button ? Thanks Geneo
I have 2.5 hp 21gal stand up pressure switch needs replacement, where to get one?
thank you for offering a place to post. I am finding that the valve that controls releasing pressure from the tank to the tool is not opening. Nothing changes, tho, unpredicably it worked for about 10 mins today…Any suggested fixes for that?
So I usually have to empty all the air out of the compressor before it will start and if it’s cold it is even worse I have the 2.5 21 gallon upright I was wondering if this ‘t’ fix would help if so pictures would be nice 😉
I have a central pneumatic air compressor model# 67847 2.5hp 21GAL 125maximum psi and it keeps shutting off right at start off I plug it in hit the on button runs for like 3sec and shuts off
I have the same one as Noel and every time we turn it on it’ll be on for a few seconds then the reset button pops out and it turns off.
I have a 21gal stand up or the central pneumatic and all of a sudden it stopped building pressure. I used it Thursday just fine started today and it wont build pressure. Help
I’ve seen a lot of comments on the 21 gal Central Pneumatics air compressor with starting issues. I tried all the suggestions to get mine to start consistently – new cold start valve, new capacitor, checked the bypass valve. I cured mine by putting a tee in place of my cold start valve and then put 2 cold start valves into the tee. They still close at 2.5lbs of pressure but it takes a second longer to close allowing the motor to get up to speed. Working like a charm now . . .
I have a 10gal 2.5hp central pneumatic air compressor the oil fill cap blew off where can I get another one
I have a Central Pneumatic air compressor #69669. Where can I get the three eared inlet valve reed?
Just wanted to give everyone an update on what ive recently done to my troublesome 21gal 2.5hp compressor. So after the 3rd reed broke on me I decided to trace the good reed i had left onto a piece of .012 feeler gauge. I shaped it to match almost exactly and put it back together. Only this time i drained the HF compressor oil and filled with Mobile 1 full synthetic 5w 20. Also loosened up that start valve right next to cylinder head so it was still snug but not tight. Drilled 3 more holes in air filter housing. Since doing this it no longer trips either house breaker or motor breaker on cold start or any start thereafter. Is actually a useful compressor now. Tripping breakers and breaking reeds was a constant issue before. Havent had either happen since. Thought Id throw that out there to help others because HF most likely will not. Good Luck.
I have a 69669 air compressor. I nedd a compositor for it where can I get one?
My central pneumatic compressor will run and build air but compressor won’t kick off. What is the problem?
My compressor will build air but not kick off it keeps running.
I have a model #47065 21 gal and the compressor wouldn’t build pressure. I took off pressure switch and took it apart and noticed that the rubber diaphragm has holes in it. Where do I find a replacement diaphragm.
can’t get the Red Knob on the pressure regulator to screw down to adjust out going air
pressure. anyone with suggestions?
That black “reset” button just sits flush in the housing it’s in. Doesn’t really push in at all. Zero pressure on guage, compressor never shuts off, just keeps goin. How can I address this?
I think Harbor Freight should exchange Model 62803 21gallon compressor for customers who got stuck with LEMON COMPRESSORS. Im sure they are engineered to last just outside the return policy window but if it gets even light use it will become apparent that it only looks like a functional compressor. I will not buy another big item from Harbor Freight until they show some interest in customer satisfaction.
I have a Central Pneumatic 21 Gallon 2.5 hp 125 PSI Compressor. Air pressure would not build over 20 PSI. Replaced reed valves and it came up to 120 PSI and cut off as normal. As I released air with blow gun as pressure dropped , the compressor wouldn’t kick back on. Completely drained tank and again tried on off switch and it would not come back on.
I have the 2.5 horse with a 21 gallon tank, 125 psi. When go to turn on it runs for about 5 seconds then kicks the reset button on motor out. Started out intermittently now does it everytime no matter how much air pressure is built up. It was bought brand new 2 years ago. Any help is appreciated thanks
the thread where the unloader tube connects to the check valve ( on the check valve) is stripped- any way to fix? or where can I get a replacement check valve?. This is the 2hp 8 gal model. Thanks
I am looking for a Central Pneumatic 62803 21 gal. 2.5HP 125 PSI Air Compressor uploader tube. Harbor Freight customer service states they do not carry the part.
What should my tank pressure gauge read on my 17 gal, 150 psi CP air compressor model 68066 when fully charged? Don’t need a 10 paragraph response!
my 2.5 21 gal. 125psi will not start up if air is in tank..it drags then pops breaker. Help!

I need an output regulator for my Central Pneumatic oil-less air compressor MN: 99780;: Max pressure; 155psi; air pressure out; 125 psi;air flow; 6scfm at 40psi; 4scfm at 90 psi; tank capacity;17 gal. motor; 4hp at 13,rpm.
Thanks
I have a Central Pneumatic Air Compressor MN:99780. It compresses the air to about 145psi the drops to 125psi as it should. The problem is that no air discharges from the tank which is full. I found no clogged lines and believe I need a new Out-put regulator. Harbor freight does not have spare parts for this compressor. What can I do?
Have a Central Pneumatic 2 HP 8 gal 125 psi model 67501 air compressor. motor just hums and trips reset button when there is pressure in the tank. Release pressure down to 20# , hit reset and it will pump up to normal pressure. Any ideas on the problem. It doesn’t have a start capacitor so that is out. Does the run capacitor have a dual purpose? Thanks for your help.
Compressor oil not showing on gauge. Runs fine.
my 2hp 8 gallon compressor only pumps to 40lb psi with reguator wide open
WE HAVE A CENTRAL PNEUMATIC 9 GALLON 212CC 135 psi Wheelbarrow Air Compressor 69783 and the pull cord pulley has messed up. Can I get a replacement part for it? Thanks in advance for your help.
Compressor will start up but stops whe n it reaches about 20 #
I have a CP 21 gal compressor – model 61454 with a pressure issue. It will build up ok but when it falls back to 95 psi to restart the motor attempts to start but trips the internal circuit breaker. It appears to be pressure build up on the piston head as I can release down to 20-30 psi and it will work. Thanks in advance for any help.
