I have a compressor that has about 8 hours of time on it and now it has an issue. When I put air in line the compressor works fine. When I equalize the tank then try to fill the tank to the 300 bar the compressor freezes and will not fill the tank. This compressor has very little time on it. 



I have tried to contact air venturi air by phone 

fb page , email. They do not respond but only by saying we will have someone contact you. I have sent them video . They responded one saying Jordan called you but your message system is not set up. Find that funny because my call log shows nothing . I am not impressed by there product or there service


 
If you are trying to start the compressor with high pressure in the line the compressor cannot over come this pressure. You need to close the line, start the compressor and let it build up at least the same pressure that is in the tank BEFORE you open the line. I don't know of any compressors that will start with high pressure pushing against them.

You start by knowing how much pressure is in the tank you want to fill.Then hook it up to the compressor with the tank valve closed, when the pressure in the compressors fill line equals the tanks pressure, which should read zero since the tanks gauge only measures the pressure in the line, you open up the tank valve to allow it to fill. 

Although I've never done it as the instructions say NOT to, if you hook up a partially filled tank to the compressor, open the tanks valve, then turn on the compressor it will "freeze" the compressor as it can not overcome that initial pressure. It kind of needs a running start.

I have called Air Venturi several times for customer service and have always received excellent warranty repairs. They were done right and very quickly. You may not get through the first time, but they have always returned my calls within a day.

That is exactly what is done here. You just did not see that step. My shark tank was down to 3600 psi. I set the gauge to fill 3600 psi. I ran the compressor until it filled 3600

I equalized the tank to the compressor . It is of equal value. It will not compress.

At the point in the video you are turning the compressor "ON", your line is already charged with 3600psi, correct? If so then that is NOT correct way to start. Bleed that line, close bleed and then turn the compressor on. If you have 3600psi in tank, what happens when compressor line gets to 3600psi and you then open the valve? Does compressor keep going or shut off?

It shuts off, then I open line , equalize the tank with compressor. Then turn on . It won’t compress

You should NOT be opening the tank valve while the compressor is off, it should be done while it is running.

Sounds like you have the output pressure set too low. While the compressor is running, and the pressure gets close to the tank pressure, open the tank valve. Everything should equalize, the compressor should stay running and it should fill the tank to the set pressure. If the pressure is set at 3600psi, that is where it will shut off.

Guys am I missing something here? Blaiz1 says his tank is at 3600psi. Then he sets the gauge on his compressor to output 3600psi. Why would the compressor run? His tank is already at that pressure. Perhaps I misread something and he is not setting the gauge on his compressor to 3600psi but something else.

That what I mentioned above. I think I am reading that he is setting it to 3600, letting the line get to 3600 (so it equals the tank) and shutting off. He is THEN raising the set pressure and expecting that the compressor should then start again when turned on. It won't. It needs to be set higher WHILE running, not after it has stopped.

Like others have stated. Seem like you pressure the compressor to 3500 psi. Then shut it off then open the tank to equalize. Then turn it back on. It will not then on. Its fighting against 3600 psi. Set your pressure to 4500 psi. Turn on the compressor, when the gauge on the compressor gets close to 3600 psi, open the tank slowly. Do not turn off the compressor. Keep it running. It will auto turn off when it reaches 4500 psi.

You guys are reading it wrong. 

1 my air tank is a 4500 psi, It is down to 3600 psi from use.

2 I set the compressor to 3600 psi.

3 when I fill the line , it shuts off at 3600 psi. where I set the gauge.

4 when I equalize the tank to the line / compressor then turn compressor back on, the compressor will not run 

this is the issue.

I have never had an issue with this until now. I am going to ask you you guys would like to see a complete video of how i do it. Because I can. I took steps out because of time. 

i do thank you for the help. Air Venturi has not helped me at all so I am thankful you guys are here to help

That guy is doing it wrong. One guy does it that way doesnt mean it's the right way. You clearly stated you set it to 3600 psi and it shut off then you open the valve and turn the compressor back on. It's trying to go against 3600 psi. Just cause it worked few times for you before doesnt mean it's the right way. Do you ride your bike up a hill. Stop midway and then try to peddle it again? You will fail. Once you start going up hill, you use that momentum to continue all the way. Everyone is giving you advice to keep to compressor running so do not shut it off, just open the tank and it will fill to 4500 psi. Yet you keep shutting it off at 3600psi to match your tank and you blame it on the compressor lol. Most compressor will not run if there is pressure in the line. Some may do it but you will damage the piston over time. It's not the correct way to do it. The correct way to fill your tank is, set the auto shut off to your desired pressure, then start the compressor with the bleed valve open so you know there is no pressure in the line. Give it a few seconds then closed the valve. Once the pressure on the compressor gets close to the pressure in your tank, you slowly open it. The compressor will keep running to whatever you set it to shut off at. Never shut the compressor off and then try to turn it back on with pressure in the line. If you do need to shut it off for whatever reason. Always bleed the lines first before you try to start it again. It's not the compressor fault. Its users error. Ask anyone on here if you dont believe me.

2 I set the compressor to 3600 psi. (Set compressor to 4500)

3 when I fill the line , it shuts off at 3600 psi. where I set the gauge. (it will keep filling past 3600 - not shutting off)

4 when I equalize the tank to the line / compressor then turn compressor back on, the compressor will not run this is the issue. (Now open the valve - the compressor will keep running till tank gets to 4500)

I am reading it EXACTLY as you typed it, which is INCORRECT procedure. You do 'NOT want compressor shutting off anytime before it reaches 4500

PigeonMan, BigTinBoat, and bandg are correct. If you want to make the process easier you can install a check valve between the compressor and the tank. This would allow you to open the tank regardless of the pressure/line differential, allow the compressor to run continously until the line pressure meets or exceeds the tank pressure, and then the check valve would open up and begin filling the tank. This may be a better method for you and is what some valves in tanks already have. The direction of the check valve would be to permit flow from the compressor to the tank. Tank pressure in excess of line pressure would close the check valve allowing for the line pressure to build.

I believe these forums to be a better source of information than YouTube videos -- sadly there have been a few significant (but not intentional) errors made in some of these videos for various compressors.

Same opinion on procedural error here. I don't know the Air Venturi but my Yong Heng will surely refuses to turn on if the same procedure is applied. I don't fill tanks but rifles + big gold filter directly. To the compressor, there is no difference because all it sees is pressure it works against at the outlet. The kind of equipment it is connected to doesn't matter. 

The fact that you were able to get the compressor running in the past can be due to either :

1. The start pressure was lower

2. The compressor has got a really strong motor but the high start current has produced sparks at electrical contacts which got erroded over time limiting the amount of current that can go through so it could not start under the same pressure now.

Anyway, I would strongly suggest you to try the suggestions in the other responses. It is very likely that you will get it working. You may also want to check the electrical contacts including those inside the relay to see if there are signs of overheating.
