Yong Heng stop auto-stop

[Eaglebeak]

Has anybody disabled the auto stop function on this compressor?I would like to fill to 300 bar and bleed the pressure before switching it off without it auto stopping early. I have a suspicion that it may be as easy as disconnecting the wires that lead to the manometer. Mine seems to trip at about 285 bar.

Bleeding the pressure while the compressor is running will not shut it down or activate the auto stop function. If yours is shutting off at 285 even though it reads 300 why not just move up the auto stop pressure shut off to 315 to compensate for the gauge's calibration error? Yes, disconnecting the wires to the gauge should disable the auto stop feature. My
compressor has a plug connected to the gauge and if it is disconnected the gauge only reads the air pressure but won't shut down the compressor.

Thanks, Humdinger. My model is the non-adjustable auto-cutoff version. I just want to be able to bleed it down as per instructions before it cuts out early automatically. I have only tested the unit to check for leaks and see at what pressure it would stop. When I let it reach its cutout pressure I heard a pop and hiss from the low-pressure blow off valve. That I assume means that high-pressure air is leaking back past the check valve to the low side. I want to avoid this happening by purging the pressure before switching off. I won't be losing air from my tank, as I have a non-return valve in my fill line. As you know the instructions are very vague, I don't know why they would add an auto or adjustable stop if it was going to cause damage to the unit if it is deployed. I would rather be able to override this nonsense. There is always the burst disk as a safety fuse if need be.

Have you tried running it again since you let it hit the auto stop and heard the pop? That isn’t normal. The same compressor with the adjustable auto stop is designed to stop at the set pressure. It just stops, no noise. Then one shuts the fill valve to the tank, and opens the compressor bleed valve. Once pressure had bled off, run the compressor for a minute with the bleed valve open to remove any moisture from the system. Don’t forget to start the compressor with the bleed valve open, and run it for a minute before shutting the bleed valve and filling your tank. Also, don’t open the fill valve on the tank until compressor pressure is within a few hundred psi of tank pressure. And as has already been discussed a lot on AGN, use a good synthetic compressor oil and an additional filter-dryer.

Thanks, Centercut. I just topped my tank up from 260 bar. Everything went well and it took about 10-15 minutes to reach 290 on my manometer that was scavenged from the backpack that my bottle came with. I think it is pretty accurate. I have compared it to the gauges on my guns and a few others that I have on fill adaptors and my external reg. All my gauges read within + or- 150 psi of each other. Anyhow, this time it shut down normally and there was nothing leaking back to the low-pressure bleed- block. I'm using the Tuxing gold filter filled with the 13x type Zeolite. I'm a little concerned that the media contained some fine talc-like powder mixed amongst it. I have it sandwiched between about 11/2 inches of the tampon. Do you think that it is enough to catch this dust? I can imagine that it would shrink quite a bit under 300 bar of pressure.

 

[Centercut]

Yes. A 1 1/2 inch tampon on either side of the Zeolite is fine.

hello guys i have a got my bottle to 300 bar and the compressor is running at 4600 psi is this the max or can i get the bottle to 350 bar?

I had to put 2 explosive copper discs in to get it to work this smoothly

Thx

Steve

I fitted 2 copper discs to the blow off valve and it runs at 300 bar or over 

 

[Eaglebeak]

I think that you will find that your bottle is only rated for 4500 PSI or 300-310 Bar. I don't know about your compressor. It's OK to exceed the tank maximum by a few hundred PSI to allow for a drop when it cools down. Otherwise, stick to the specified limits.

It no need for zeolite in the filters.

Just make a roll from bounty paper towels and press it in the filter it works very fine.

In the small yong heng filter it works for 1 fill on at 0,5 liter bottel from 130-250 bar before getting wet.

This Bounty paper towel takes the moisture better from the hp air than zeolite or this cotton tampons

May I know how you came to this conclusion ? zeolite can take water out of the air when it is still in vapor form but paper can only soak up water in liquid form. How can paper be better than zeolite ?

Try it yourself and you will see how fine it works
