Central pneumatic 3 HP - 8 gallon Model 90385 air compressor

Forgot to turn off - hose broke during the night, and ran for who knows how long till shut off in the morning! Worked O K for awhile - but now it won't hold air because of air leaking out of the oil fill tube? Any help would be appreciated also, where to buy parts! Thank you!

I just bought a craftsman pneumatic 1/2-in drive impact wrench. And used it with my craftsman 4-gallon 1hp air compressor tried to loosen the bolts on my car wheel wouldn't loosen them help

Pneumatic tools are rated in cfm (cubic feet per minute). Your 1 HP air compressor is rated at probably not more than 3 cfm while the 1/2 " impact driver needs at least 8 cfm, maybe 12 chm of air.
The compressor must provide more chm than tool rating needs.
It is a problem, by the time you look at five horse power air compressors and larger, a lot of electric power is needed. A circuit of 220 volts, 20, 30, or more amps would be required to run those large expensive compressors.
If you can, return the air tool and get a good electric tool instead.
Leave those high air volume air tools to shops that are so equipped to use, or invest if you must.

Blows fuses, will not run. not used much, 2 years old

Wild guess rust Does it have a tank? does it have a condensate drain? Are you sure the starting condenser is ok? It sounds almost as if the piston is frozen. Sometimes this kind of thing happens to Airconditioning compressors. You might try a "slow blow fuse" and increase fuse capacity. There is a "hard start" kit which is an extra starting electrical condenser so if none of the above helps and no warranty and mine I'd spray a tiny bit of wd-40 into the intake let it sit overnight. try again.

Why use 1/4" coupler/fitting with 3/8" ID hose.

Hi Jason! Something to remember. When you refer to a 1/4" fitting, they have 1/4" NPTF (pipe thread) connections which isnt 1/4" in diameter. It is actually .540 diameter and your 3/8 hose is actually .375. On most air hoses you find, 1/4" fittings with 3/8" hose is REALLY common and considered the standard for most common air tools.
One thing that I have always taught people when it comes to pneumatics is to know the air requirements of your tools. If an impact you have has a 1/4" inlet, well the manufacturer calculates that size fitting allows a sufficient amount of air to operate it at the best performance. So, your 1/4" fitting with 3/8 hose should be fine for equipment with 1/4 connections. If you have a tool that has a larger 1/2" or 3/4" inlet, well you need to step up you hose to at least 1/2 fittings and 1/2" hose.
All pneumatic devices have a certain amount of air that they will need to run correctly. This is the CFM (cubic feet per minute). The compressor can only put out so much. Most of your smaller compressors dont put out alot of air (cfm). A good rule of thumb is on electric compressors, 4 cfm per horsepower of the motor (2 cfm per hp on gas operated). So, if you have a 5 hp compressor, figure you will only have a maximum of 20 cfm available. Check your tools, see what their consumption will be. You may find that you may not have enough compressor so putting on larger fittings and a larger hose because your tools demand more air may not be the fix if your compressor cant create enough air. Hope this helps! rex

I have central pneumatic 21 gal. air compressor. The unloader valve is broke. The power switch is a fenwai model: fw-10. Where can I buy a new unloader valve?

If you should mean the switch that is pressure controlled that turn the compressor on and off- that is a fairly universal replacement piece, As is the power switch itself

If you needed that specific part, your best bet is Harbor Freight tools who owns the Central Pneumatic domain.

I have a 2 HP-8 Gallon Model 40400 Central Pneumatic compressor and for the first time when filling I hear a high pitched air leak but cannot determine where it is. What suggestions do you have to...

I would go through everything that you have where you have connections or drain valves. Spray some soapy water around and you will be able to see the air bubbles. Another thing to do, I had to do this to mine when I took one to cold weather, was go through and remove all the fittings then put more plumbers tape and reinstall everything

I have a Central Pneumatic, 21 Gallon, 3HP air compressor. The compressor is exiting air through exthaust port.

If air leaks when motor is off, fault most likely in-tank check valve. Follow discharge air line from pump to tank. Brass/steel valve at tank is the check valve. Remove hose to valve and check for leak. Replace as needed. If air is leaking while motor is running fault could be reed valves in head. Faulty reed valves in head, or torn head gaskets will cause very hot discharge air and tank will most likely never fill to shut off (or take a very long time to fill)
