Got my Yong Heng compressor

euler357 · Nov 2, 2020

The Avenger has fill up to 4350psi with up to a 3000psi regulator which is high for less-expensive PCP. The issue is that you need a tank / compressor over 4350psi to fill it and it won't be able to fill as many times. Also, you can only accurately shoot when the tank pressure is over the regulator setting (3000psi?).

For a Benjamin Marauder Field Target, you need a 3000psi fill and it has a 1350psi regulator pressure. This means that you will get many more fills from a 4500psi tank and it will shoot accurately down to 1350psi.

Filling a rifle directly from a Yong Heng isn't a great option because of the set up time, non-portability, noise, etc. If you have a single rifle that you fill with a Yong Heng, it will not be a great experience. The Yong Heng is great for filling a medium/large tank but needs additional filtering around it.

A 97cu ft (large) tank will fully refill (3000 to 4350psi) an Avenger 5.5 times. The same tank will fully refill (1350 to 3000psi) a Benjamin Marauder Field and Target about 37 times.

In my opinion, someone starting out in PCP should get either a small compressor (Traveler, Nomad, or other oilless similar) [fill time = 5 or so minutes] or medium/large tank [fill time = 10 seconds] if they have access to an HPA air source [paintball shop that will fill it, probably ~$20-$30 to fill a large tank].

I've seen this one on Amazon that seems to have good reviews but I've not personally used it. I have a Traveler that works fine but it much slower than using a tank.

BTW - a small compressor can't easily fill a large tank. The small compressors can only run about 20-30 minutes before they turn off due to overheating. It would take many (20+) cycles of overheating/cooling to fill a large tank and it isn't good on the compressor.

Does fine filling my 80s to 3000 psi, but maybe the difference is I don't need to max out its rated PSI. I have a couple of Low Pressure 2400 psi steel 100s I plan to try as that will provide even more air for blowing the main ballast tanks and should stress the pump less.. My experience is using ice water keeps the pump from overheating.

Yes, it's for a sub.

The omega trail charger looks interesting. It has a self contained water cooling system and a grease pot. It will run on 12/110v and is priced at $840. https://www.airgunsofarizona.com/co...-charger-4500psi-portable-12v-air-compressor/

By small compressor in my previous post, I mean an air cooled small compressor like the traveler, nomad, and others don't do well on filling tanks. The Yong Heng does ok for me on the 97cu ft tank at 4500 psi but I do it in 2 sessions. The tubing and filters start to get really hot. The water jacket is only on the head on mine. I'm expecting some repairs at some point but the parts seem to be readily available.

I did use my traveler to fill my first Benjamin tank but it took 5-6 sessions over a couple of hours. Most of these small air-cooled compressors say that they aren't meant to fill things over .5L.

The "one to have" is the Alpha-Carette if you are willing to spend the $1400+

BTW. Joe Brancato at Air Tanks for Sale is easy to deal with. I recommend calling him if you want a tank or high-quality compressor.

This is not really correct. Yes, you can set and shoot the Avenger at that high 3000psi regulator pressure. If you do you will mostly be wasting air. The Avenger has an adjustable regulator. I got my Avenger from BigTinBoat. He had is tuned for target shooting. Shooting pressure was 1400 psi. It shot very consistently at that pressure.

I needed more punch for critter control and raised the pressure to 1800 and (according to the webs) should be over 30 FPE.

Factory regulator setting is 2600 psi. That is about its maximum punch. But IMHO, it is the not needed in most cases.

So to circle back to your topic, it would be fine to fill the Avenger to a lower pressure than 4300. You will just get less shots. You do not need to refill at 3000PSI. Just refill before you get below your tuned regulator pressure.

Being new to PCP. I am not "sure" what I need. I am shooting around my house right now. I have an Avenger, so I can easily get 40 shots and much more if I tune it for targets. That is a big enough shot count if any of my powder burning friends want to "test" it on the vermin around their house. Currently, I don't see traveling and/or competing with a PCP.

I am just about to push the button on an Avenger. I figured I would see if you learned anything else about your rifle before I do. I have read or watched just about everything I can about it.

Click to expand...

I only have about 300 pellets through mine so far, but it has been true to the literature. It is a lot of gun for the money. Very adjustable. Very consistent. The PO put a carbon fiber shroud on it and it it really quiet. Decent trigger. The high 4300 tank provides many shots if you tune the gun to shoot at 1400 psi.

While it is well made, it is not a show piece. No nice stock (plastic).

I am very happy with this being my 1st PCP. I will learn a lot playing with the setting. And at the price point, I wont feel like I am ruining an heirloom if I do something wrong.

Yes, you are correct - this is very dependent on specific setups. I used the published pressures on pyramydair.com since I don't have an Avenger. You can certainly fill to any pressure that you want and tune to any regulator range / hammer spring / port size etc. that the gun can do. I do have a Marauder Field Target that gets lots of shots per fill - I'm at about 750 fps with 18.13 pellets on it which is about 22fpe. Most of my shooting is with an FX crown which gets 100-ish shots at high-power with a 18.13gr .22 pellet at 815fps = 26.7fpe -- it also has a 480cc bottle so it can store more air. It's running at 1800psi regulator and 3600psi fill pressure. With a 97 cu ft tank, I should get about 900 or so shots per tank fill (>9 refills of the gun from the tank). Most of my shooting is at a target about 46 yards out so I need the velocity / energy to minimize wind effects.

I would definitely do the calculations before you buy PCP airguns / compressors / pumps. You see lots of people online who didn't think it through and complain about hand pumping an Airforce Texan or other air-hogs for hours to only get a few shots

Not a great experience.

BTW - if you are in the Odenton area, I don't mind demonstrating my setup to a limited number of people.

Sounds like you're a bit over sprung. You're only getting an efficiency of about .73fpe/cuin. That crown should be able to get at least 150-175 shots if tuned correctly. I think you should be able to back out the HS a bit and keep the same velocity. This will result in more shots and a quieter gun.

euler357 · Nov 2, 2020

I might be. I've done almost nothing to it since I got it. I have it set on power 5 (one click under "max") and the port is on .25c (it's actually a .22 but it likes this better.). I'm somewhat guessing on the 100'ish - I probably need to actually pay attention and count. I usually shoot 4x 18-shot magazines then refill it - I'll pay attention to the pressure tonight and post it. I do have a 3d printed suppressor on it that I designed that works fairly well (better than the DonnyFL that I also have but it's also slightly larger).

euler357 · Nov 2, 2020

Ok, I ran 72 shots through it and calculate that it should do about 129 shots before it gets down to the 125 bar regulator pressure.

I included a photo of my backyard range - yeah, I shoot from the spare bedroom

I've got about 46 or so yards of distance.

euler357 · Nov 2, 2020

You got me thinking about the efficiency now. I dragged out the FX Radar Chronograph and my Crown seems to have gotten faster with the same settings as when it was new 6 months ago. I was at 815 +/-3 fps in April on setting 5 + .25.30 port. I'm now at 840 +/- 2fps (across 5 shots). I'm guessing that the barrel / hammer / valve / ??? got broken in (probably 2500-3000 shots on it now). This puts it about 28.4 fpe and 1fpe / cu in which is a more reasonable number.

BTW - really thinking about getting an LCS SK19 when it becomes readily available.

I did 5 shots on each hammer setting and got this:

Min 664
1 682
2 695
3 726
4 793
5 840 (my normal setting)
Max 915

May give that 3D print a go this weekend. I have a Creality CR-10s. Thank you for the link. I have the Air Venturi Avenger.

euler357 · Nov 4, 2020

I don't know what threads the Avenger has but I have several designs on Thingiverse. If you tell me the threads, engagement depth, and shroud diameter to connect to an Avenger, I can update one for you. I'm using ABS in a somewhat modified Prusa MK3S.

The end cap should be threaded M24 x 1.0
Shroud diameter I'd guess is just a bit over 25mm OD (I no longer have the gun to measure)

Blacksmith101 · Nov 4, 2020

Has anyone with a regular air compressor thought about or looked into using a Air Driven Gas Pressure Booster to increase the pressure?

There are a lot of manufacturers of this equipment for industrial applications. Here is a link with some specs:
https://highpressuretech.com/products/air-driven-gas-boosters/

John from MD · Nov 4, 2020

You don't get something for nothing. Gas boosters got to run on something in order to pump it up to a higher pressure. Those I worked with, many years ago, were used to pump up the Oleo struts on large aircraft. We would run the booster with a 4000 PSI Nitrogen bottle and it would pump the 4000 up to 6000. I don't think they have one that will pump 160 psi shop air up to 3000 psi for air guns.

Actually they do John. Been round a few years. Most complaints with them appeared to be just like the complaints of the ShoeBox Compressor (which I have) is that it's slow.

Here it is

Here is one of the threads on it

BTW-if my SB ever gives up I will seriously consider one of these.

Well, I learn something new everyday.

The thread was a good read. I agree, they do have less moving parts than a compressor. I have rebuilt a couple in the past and it is extremely simple compared to fixing a HPA compressor. If I was 20 years younger, and were shooting more air guns, I would probably look into it.

Now that the election is pretty much lost, I am going to make our move to Florida earlier than planned. With less property to shoot on, I probably won't be spending any more money on gun stuff.
