HPA filling help
16 February, 2017, 13:09
Hi
I'm looking at going down the HPA route and have the only way I have seen people refill their tanks was by either taking it to a scuba shop every time or getting a scuba tank of say 10L filled up and then filling the smaller bottle at home.
I was talking to my friend about it and he saidto me why bother wasting more money when he could fill it up for free via his workshop compressor. IS THIS EVEN POSSIBLE OR CAN IT HARM THE GUN.
Any advice on this is much appreciated. Thanks

Re: HPA filling help
Okay,
So I use HPA a lot.
For a while I bought 2 3000psi 48ci tanks (the type you actually run your gun off) and took them to a scuba shop to fill them. It wasn't a pain as they lasted me about 4000 shots and I was running a DMR.
Then that dive shop got liquidated and all the other, few, dive shops in my area do not like the idea of that pressure in such a small tank and dislike my adapter (paintball - scuba fitting) (a quality one) even more.
So recently I bought a 5l scuba tank with a quick release adapter that allows it to fill my tanks.
Dive shops will fill it, it will fill a single tank 4-5 times and only cost me £100 second hand with 4 years left before it needs hydro testing. (MAKE SURE you know how long a tank has left before you buy it second hand).
Compressors are a pain in the a**, mostly since the shop needs to keep your bottle overnight.
If it is a good compressor with a good humidity filter it will NOT harm your gun or tanks at all.
A bad compressor or completely expired filter in one will create a sludge in your tanks which can damage them and subsequently your gun depending on the engine.
Damaging tanks just means they will not 'live' as long and are more dangerous.
Only fill with a compressor if you are confident it is a good one and the filter is in date or recently replaced.
I advise filling from a scuba shop (you may need an adapter but my original shop had one). If they don't have one, check that they will fill your tanks at all then buy a quality one.
If they still won't, buy a small scuba tank and fill it yourself
Hope this helped :D

Re: HPA filling help
Just worth noting that typical workshop compressors are only capable of 120-180psi, you need a hella expensive dive specific compressor to put out 4500psi!!
I personally run a 15L tank which stays at home, and costs £10 to have filled.
I also have a 3L pony tank which is small that i take to sites, i refill this from the from the 15L.

PS dont f8ck about, 3000-4500psi in a bottle is a serious amount of energy, essentially an inert bomb, always make sure everything is connect properly with specced connectors

Re: HPA filling help
Thanks for the input guys.
Looks like I will just buy 2 3000psi tanks and just get them refilled when I need to by my local diving shop at £3.50 a tank. Still woaks out way cheaper then gas.
