Hey guys I’m playing with my compressor and air Venturi! Because my FX is still on back order!
1576272385_8824018675df40201c44a85.24396465_image.jpg
First time trying to fill the bottle but I noticed that the gauge on the compressor and bottle are only showing what’s going in the tank !so when I stopped the compressor at 200 bar and open the release valve to turn of the compressor both gauges go completely to 0 . I thought that the value on the bottle was bad because it wasn’t reading anything so I went to take the valve off the bottle and noticed that it had a lot of air in the bottle and it scared me so Is the any way that I can see what’s in the bottle and what would I need! ? I almost blew myself up !!! Lol not good so anything would help thanks guys!! This is what’s on the bottle now!! 
 
That gauge shows the pressure between the valve and the end of the hose. It does not show what is sitting in the tank BEFORE the gauge. I am sure you know that now.

When I run my compressor, I start with an empty hose, bleed valve open and bottle valve closed.

#1 Turn on the pump, close the bleed valve

#2. When the hose has around 1000 psi, I slowly crack the bottle valve open to allow the air to pass into the bottle. The bottle and the hose will equalize pressure and then the magic happens as the pump pits air into the tank. At shut down time I close the bottle, turn off the pump and slowly crack the bleed off valve.

That gauge is either faulty or that bottle is empty. The gauge on the bottle should always show what is in the bottle. You SHOULD be able to remove all hoses from the bottle and SLOWLY crack the valve to drain the bottle. If you think the bottle is over pressure you should immediately do exactly that. After the bottle is EMPTY, you can close the valve on the bottle and bring the compressor back on line with the bottle. Then follow the instructions JimNM has given you. Also note that it is very easy to have a problem with the fittings not sealing up properly. My setup is particularly sensitive to having the fittings sealed correctly. When they are not the pressure will rise to some level (random) and stop at that point. I have finally worked out a procedure which includes checking each fitting as I bring up pressure in the hose.

Yes I understand now ! So when the bottle and compressor are at the Sam bar close the valve on the bottle and open the bleed valve on the compressor to let the air out the line disconnect the line from the bottle and insert the plug attached to the bottle and crack the valve open and it should read about the same as or close to when I turned off the compressor???

This is correct . You don’t need multiple gauges. The gauge on the compressor shows the pressure in the tank when it’s connected to the tank and the tank valve is open and the compressor is running. The compressor gauge and the gauge on the tank will equalize The tank is not going to go higher then what you filled it too so the gauge on the tank is really only there to tell you when you need to refill the tank. The critical gauge is the one on the gun . Be careful not to over fill the gun.

I just bought an external regulator which is kinda handy if you shoot a lot at one sitting or if you have a gun which uses considerable air. Two gauges one shows what’s in the SCBA tank and one you can adjust to your guns regulator setting. Let’s say 220 bar once it’s set you can shoot indefinitely only reloading pellets Especially helpful with big bore guns . It’s called tethering

Wow that amazing! But I think I’ll adjust to filling my bottle and then gun and repeat! Just so I know what my shot count will be waiting also on the FX chronograph to determine that count!! If you’re going in ! Go deep! This hobby is not cheap! But I love it ! And that is just from two break barrels ! Waiting on my FX dreamline tactical .25 cal come on !!

Even if you forget everything that has been written here … remember ONE thing … before taking off a fitting or disconnecting anything that may have pressure behind it. STOP and THINK and DOUBLE CHECK everything. A good friend of mine who used to live just a few miles from me now works at Airguns of Arizona and he works around compressors all the time, he is Raptor Pneumatics representative in NA. He knows compressors inside and out, but he plugged up a fitting on a tank and thought the QD collar was locked in place … and it was in place, but not locked completely. He only had about 1500 psi in the tank when it blew the fitting off and almost destroyed his hand, it could have took his head off. It's been years now and he still doesn't have full use of his hand, in particular his thumb. Multiple surgeries, bone grafts, skin grafts, hundreds of hours in physical therapy. If it can happen to him, it can happen to YOU!

We all love PCP airguns, but they all work off of high pressure air. If you get in a rush, if you are a little forgetful, if you don't double check everything. It could cost you your life or maim you for life. You owe it to yourself to take the time necessary to become acquainted with your equipment and safety proceedures to not let accidents happen. High pressure air will show you no mercy.

I am saying this NOT because I think you are stupid … what we are talking about is not rocket science … but there is a small learning curve. You are new to pcp airguns and a word of caution here concerning hpa just might be in order. Not trying to step on any toes or disparage anyone, I simply don't want to see anyone else hurt.

Shalom

Thanks guys! Trust me I will stop and think before touching anything before I head out to shoot! And if I can’t figured it out I’ll just come on here and ask! You guys make this hobby more enjoyable every time I come on here and ask a question! Nobody has any thing negative or think there the pcp god !! ( I’m sure some of you are) but it’s been a great experience on here! I know when I can go and get help!! Thanks again guys AirGunBeginner45 out !!

Agree 1000%. Any mistake with HPA could be damaging. It is easy to think a foster fitting has snapped into place when it hasn't. I've stopped putting fill probes in and then putting on the foster because of just this. I put the probe in the fitting and make sure it is fully locked then put the probe into the gun. And I open valves on tanks as slowly as possible.

As far as the gauges, it is not necessary but I really like the dual gauges on my GW tank. I know how much air is remaining in the tank at all times with a glance at the gauge.

If anyone has a link to the industrial air line tie downs, I would like to order some of those as well for extra safety in case of a failure.

Regarding hose restraints or "whip checks", you can easily make them yourself with any suitable cord that can withstand the initial force of a disconnect. It will prevent the initial potential for injury from impact and thereafter keep the hose from whipping about and allow you to close supply valves safely.

You can test the whip check material by tying it off to a long hose or other representative item that you can whip to ensure it's strong enough; you'll be surprised to find it doesn't take braided steel :)

Just make sure you attach the ends by choking it as close as possible to the end of the hose to minimize the whip effect, else the hose will be restrained but still whip about. Also, don't attach it too close to the end or it may slip out.

I have worked with high pressure/volume air for most my career and used the industrial versions daily. I have witnessed them in action and know what works.

Yeah, I have the dual gages on my Omega 74 footer. Bought it from Joe B and absolutely love the way I can slow fill a gun from the tank now … before I got the fittings from Joe, I would have to hold my breath hoping that I could keep the fill as slow as possible but his fittings made that a thing of the past.

I used to drive one of those big ole 10,000 gallon gas tankers at work for about 30 years before retiring in 2015 and we had pumps on the for delivering gas or fuel oil to above ground tanks. I was taking 7500 gallons of diesel to a hazardous waste treatment plant one night and whenever we went there they would have someone accompany me to the storage tanks and stay with me while unloading. I pulled up to a aluminum sided building where the tank piping was located and had to run a 4" diameter 20 foot long hose through a hole in the wall to their fitting for the tank. I got all the lines hooked up and pumped off the load. Afterward, the helper wanted to assist me taking everything down and put back on the truck. I had the PTO still running and told him that I would have to blow the lines out and to be sure not to take any fitting loose until he heard me cut the engine off (because he would be inside the building and I would be in the truck) I went outside, got in the truck, revved the engine up and blew the lines out to get all the diesel out of the hoses as best I could. Then I let the engine idle and was fixing to cut the PTO off and the truck when I heard an incredibly loud BOOM! 

Apparently he had forgot that I said not to take anything loose until I cut the engine off and he had started loosening the ears off the fitting when he heard me idle the engine thinking the PTO was off already. I ran into the building as fast as I could praying that the hose hadn't cut him in half, but he was laying up against the wall knocked out with all his fingers missing from his right hand. I picked them picked them up and put them on ice, but I knew it was useless because all the fingers were just hamburger and bone splinters. 

Somehow, for some wierd reason ... I still carry around a strange sense of guilt over what happened, even though I told him everything he needed to know ... you know ... all the "what ifs" that run through your mind years later. He lived but he went through alot of pain and was disabled for the rest of his life. Like I said before, HPA takes no prisoners and has no mercy.

y’all stop ! y’all are scaring me !! Safety check! Safety check! So what dull valve system you have on your bottle do you have a link for what you have? I would like to know what I have left also in my bottle ! Putting the stop plug in is a nothing hazardous thing I have to do in the process! I would and like to hav a system that all I have to do is connect to bottle from the compressor with a one way valve so I can bleed the hose coming from the compressor without losing air from the bottle one less thing to think about and after that close the bottle valve and release the one way foster fitting and then hook up my fill line that is already to connect to my gun witch I already have I just need another gauge to show what’s in the tank ! I am not a plumber so figuring out what I need is a pain so that’s why I have so many fittings that I didn’t need lol ! what I have now works just need a diagram of the set up ! My hart can’t take much more of this! Make me quite drinking just to shoot my gun ! Lol !!

A little fear of something that can kill you seems to be justified-makes one careful. Few accidents seem to happen but there have been reports of a couple on this forum-foster fittings coming apart and hoses breaking as well as some "less than cautiously modified" guns coming apart. Caution is warranted but by all means enjoy the hobby.

Search airtanksforsale.com and read about the things Joe Brancato has available-not the only option out there but he seems to be well regarded by most. I have his DUAL GAUGE (not dual valve) setup on the largest 4500 PSI tank which shows pressure in the tank on one gauge as well as line pressure on the other. Not necessary by any means but I view it as a nice setup to have. He also has what is called a SLO-FLO VALVE that seems to make it a bit safer filling a smaller cylinder since the valve limits how much flow can occur how quickly. I feel safer using it but very cautious control of a regular valve seems to be good enough for most users. A large HPA tank without that feature COULD over-pressurize a small gun cylinder pretty quickly if it is cracked open too fast but again most people seem fine without it. Even with the slo-flo valve my HW44 cylinder fills very rapidly and has to be watched closely. Enjoy the PCP shooting but use caution.
