AS 196 Twin Cylinder air compressor

Hi my compressor is a as196 twin cylinder with a tank.


The issue is that after a minute or so it begins making a knocking sound which gets worse the higher the pressure gets....

The compressor seems to be working as well as ever but I wonder if it's on its way out and would rather try to fix it now....

Any ideas would be appreciated thanks

A bit hard to diagnose, David, since I cannot hear the noise.

I'm happy to post this in the event that another AS 196 air compressor user has had the same experience and can comment.

 Knocking sound
by: Anonymous

I had this problem on a TC 848 four head unit and found that the shaft on the eccentric weight had sheared. The knocking was caused by what was left of the shaft hitting the connecting rod and banging it around inside the case.

 Knocking noise
by: Dennis

I've got the same problem. The compressor runs just as usual building up some pressure. At around 20 to 30 PSI, the sound is becoming louder until finally it has this knocking sound of metal against metal.

Maybe a worn compression ring?

Airbrush compressor AS-196 problem

AS-196 mini-air compressor

Question: I just bought a compressor but for some reason it seems to not be working right! at the beginning, everything was fine but about 10 minutes of be using my airbrush it started to sound like if the compressor was releasing lots of air from where I believe is the solenoid valve. the pressure can't hardly gets up;however, when I close the hole (the Solenoid valve)with my finger and the air can't go out, the pressure star raising again! I hope you can help me with my problem!!! thanks

Response: Ali, I think, from what you have written, is that you have air bleeding out of the unloader valve, and that is a symptom of a bad check valve. See Check Valve from the site map page to read about what they are and what they do, and see if that helps.

Your compressor is a Chinese import, supplied by Fenghua Bida Machinery Manufacture Co., Ltd. Website: www.allproducts.com/manufacture100/bida/Product-2007101113223.html. The actual manufacture appears to be Ningbo Haosheng Pneumatic Machinery Co., Ltd. You can, perhaps, contact them directly for technical assistance.

 Relif or check valve issue
by: hekza

Same problem is appeared today. There is an air leakage from solenoid valve end (from hole point)

Note: Solenoid valve is existing of 2 pieces: 1-magnetic part, 2- relief valve

So problem can cause due to relief valve's diaphragm damage
or Check valve is not working properly.

relief valve, and check valve sold seperately so it is important to identify the problem exactly...

In this case you need some technical hands to identtfy which parts are not working good.

This will save your money, otherwise you need to buy new parts and try.

 AS 196 loose part
by: Bill

Robert, made in China, quality is suspect, no way can I tell from here what part is rattling around inside your AS 196 tank, or even if what't in there is a part of the compressor.

I cannot advise you to use the compressor as I don't know what's clinking.

However, you might test the compressor to see if it works properly. If not, ask to return it for another.

 Loose objekt in tank
by: Robert

Hi!

I’ve just bought an AS-196 Compressor but when i unpacked it I could hear a loose object moving around inside the tank. What part can that be and can I use the compressor although that part is no longer attached?

Regards,

Robert

Thank you Bill, I'll strip it down tomorrow and see if there is anything I can do, if not I'll have to dig deep into my pockets.

 Mini Airbrush Compressor (AS196) slow to fill
by: Bill

Well Steve, they do wear out, and it sounds as though some part of your AS196 Airbrush Compressor may have.

For some ideas on what changes on a compressor so that it runs but doesn't build pressure, or doesn't build air pressure as fast as it used to, see the troubleshooting page on that topic.

If you are handy you can tear down the pump, but I suspect that given the compressor is made in China, parts may be in short supply.

Keep us posted, will you?

Bill
