Wo1f Posted December 22, 2017 Share Posted December 22, 2017 I’ve gone over to the dark side (for testing at least) and bought a hpa kit. Bottle, Reg, line and valves. The issue I’ve got is I have no idea where to get it filled up. I’m in the Wigan area. There’s a dive place a few miles away called shipmates, but when I phoned them, they said they don’t fill ‘paintball stuff’. Any suggestions?

Root Admin proffrink Posted December 22, 2017 Root Admin Share Posted December 22, 2017 If you can't find somewhere willing to use the paintball adapters, just buy a dive tank off eBay and have that filled - it's an extra expense but worth it not only because of being able to get it filled anywhere, but also because it'll give you between 3-5 good refills of your shot tank too (so you can take it to games or be able to test your gun at home without fear of needing to do another trip to the shop). A 232bar tank can be had for sub £100 off eBay. Just check that it's within its life and also has a current test (they need testing every 5 years). You'll also want a Yoke type 'refill station' (an adapter so that it get connect to your actual tank). I'm going on the assumption that this is for a 3000psi tank by the way? If you're using a 4500 then you'll want to look for a 300bar dive tank. Link to comment Share on other sites More sharing options...
Supporters Shizbazki Posted December 23, 2017 Supporters Share Posted December 23, 2017 Most dive shops dont have the adapter that fits our HPA tanks. Like Proffrink says, get a scuba tank and fill station and go from there. Link to comment Share on other sites More sharing options...
Tommikka Posted December 23, 2017 Share Posted December 23, 2017 Air fill options not necessarily in order of preferance are: 1) at the site you play (may not be an option as HPA is not the standard for airsoft, but with sites diversifying it’s common for independant Paintball sites to run Paintball, airsoft and laser tag etc - look around to see if you have a suitable site nearby. Major chains such as Delta Force are likely to be geared up for punters only and run CO2, independent sites that take walkons will run HPA) 2) at an independent Paintball site Sites give free fills when you play, and tend to be less keen on someone turning up just for air, as there’s no business for them to fill paintballers cylinders for use elsewhere - and the ‘customer’ could be up to something chavvy/unsafe. Pop round for a chat and you may get to pay per fill 3) at a dive shop. Even though they said they don’t fill Paintball they may be willing if you ask them about you bringing a fill adaptor. Be wary that dive shops operate in bar and we operate in psi. No problem if they know what they are doing, but weekend staff have blown burst disks filling 3000psi to 300bar 232bar is approx 3000psi 300 bar is approx 4500psi You would pay per fill, so pay the same for a small cylinder as a diver would for a large cylinder You may be able to extend the hydro test timeframes on a scuba cylinder by having it marked ‘surface use only’ but check with the dive shop as they may not fill surface cylinders 4) via a dive cylinder. Buy a scuba cylinder and a fill rig. Get the scuba cylinder filled at the dive cylinder then use your fill rig to fill your airsoft cylinder. This is expensive up front, but you then pay per fill at the dive centre Only part fill you airsoft cylinder to less than the scuba cylinder. Every time you fill they try to balance out the pressure, if you have a 232bar / 3000psi scuba cylinder then by fitting your airsoft cylinder that 3000psi of air goes into a larger area capacity across both cylinders which means the pressure drops, if you empty it then fill again the overall pressure drops etc. Keep going for maximum fills and then using it all then you lt scuba cylinder loses pressure fast sending you back to the dive shop to refill Instead stay low, fill the airsoft cylinder to 2500-2800psi, which means the scuba cylinder keeps a higher pressure. Don’t wait until the airsoft cylinder gets low - if the site will let you then bring your scuba cylinder to the site when playing and top up between games which will preserve the maximum pressure in the scuba cylinder for longer For more expense and maximum fills buy two or three scuba cylinders and cascade from them - 1 for main fill from empty and the scuba will drop quickest, 2 for a top up, and possibly a 3rd to maintain almost 3000psi If you get a regulated fill rig or are very careful) you can use a 4500psi scuba cylinder to fill a 3000psi airsoft cylinder and get full 3000psi fills for a long time Ask your airside site and they may bring in a scuba rig themselves for HPA players 5) via a stirrup pump This will give you lots of ‘free’ fills but take time. You will grow muscles and learn how often to top up Make sure it is a valid high pressure stirrup pump (usually sold for PCP air Rifles) and avoid saving some money on dodgy imports Ensure it is suitably filtered, noting that any contamination will at best clog up the regulator and result in a burst disk failure one day, and at worst cause a flash fill explosion once filled at a later date when filled by compressor and heat gets involved 6) by compressor. Domestic and workshop compressors are no good as they can’t reach the pressure required - and cause contamination Your would need to spend thousands on a diving compressor 7) with a ‘shoe box’ booster compressor couple one of these to a workshop compresser and it boosts the pressure. It will still take ££s, is very slow (taking days to fill) and the source compressor will keep stopping from overheating Link to comment Share on other sites More sharing options...

I work with compressors day in day out, we have 232kw compressors that run 24/7, we have 4kw compressors that run 24/7, they only overheat if they are broken or not serviced properly. 1bar =14psi You may be able to find companies, like BOC, who use HPA compressors to fill tanks that are willing to fill tanks for you for a small fee. Just have to be friendly and ask. Link to comment Share on other sites More sharing options...

Fair point - a proper workshop compressor that’s meant to work constantly will do the job, but those that I’ve often seen proposed for use with a shoe box as a cheap solution (often ‘domestic’ workshop compressors) aren’t up to the job or aren’t looked after. Still not an ideal solution, and should be used by those who really do have few options and do so wisely. The shoebox compressor was hyped as the perfect solution to people’s home needs in Paintball and generated a few disappointments Link to comment Share on other sites More sharing options...
Wo1f Posted December 23, 2017 Author Share Posted December 23, 2017 Thanks for the replies guys. Lots of great information there! I’ve just realised why I hated hpa and hadn’t bothered with it now lol. I think the dive bottle is my best bet. A small 3L one.. I’m not going to be using it very often at all and there’s a dive shop down the road from me. Thanks again! Link to comment Share on other sites More sharing options...
wiggle5 Posted January 4, 2018 Share Posted January 4, 2018 I know this thread is a few weeks old, but my local gun/airgun shop fills bottles for PCP airguns which are probably fairly similar to an airsoft HPA tank? you might have somewhere like that nearby Link to comment Share on other sites More sharing options...
Root Admin proffrink Posted January 4, 2018 Root Admin Share Posted January 4, 2018 Same fill nipple thingy as it's fairly standard so yeh, you should be fine. Link to comment Share on other sites More sharing options...

Aengus Posted January 5, 2018 Share Posted January 5, 2018 Could also buy a personal air compressor. I'm planning on saving up for one of these: link Link to comment Share on other sites More sharing options...
