Love my alkin w31

[airgunmike56]

Noticed my tanks were only filling to 4300 to 4400 PSI, So bumped the W31 to 4800 PSI, Just a little more air in my tanks, And yes I know my tanks will blow up and I will explode from the little extra 300 PSI, And all my guns will stop working , Except the Hubens, LOL,

Mike, I wish we were neighbors!

Best airgun related investment I ever made was the Alkin W31

@airgunmike56 Mine seems to stop filling around 305 bar. How’d you make the adjustment to bump up the fill pressure?

Is yours auto or manual stop?

You can add a little more pre-load to the pressure relief valve.

Loosen the locknut on this part (red circle) and then turn the top hex clockwise. Start with 1/2 turn and see what psi increase results, then go from there. Lawyer statement: Don’t exceed manufacturers recommendation.

Be careful I loosened the lock nut and turned it maybe a 1/2 turn , My PSI jumped to 5,500 PSI , I turned down a tiny bit at a time took me 3 or 4 times to get it to 4800, and that was my goal,, My Hubens will just have to suffer ,

I know it’s an Alkin, but do you think it’s worth stressing out parts for a couple more hundred psi?

 

[airgunmike56]

If 300 psi more is going to stress out my parts , Well if I was bumping to 5300 PSI NO, As I was told the thing is made to perform 5000 psi for just about forever doing airgun duty,, There not another air gunner in 300 miles of me , Its not going to get a lot of work, LOL.

I think it depends on when you got your Alkin which pressure switch you have on it. Also maybe the auto and manual have different pressure switches.

Mine has a pressure switch which is the same one which my F10 Shoebox had on it. IMO this pressure switch is not super accurate and can/will change a bit over time. I noticed my fills were only going to 300 bar instead of 315 bar so I made small adjustments testing each time. As with the OP you just need to go in small adjustments and test the cutoff each time.
