Problem with Altaros Booster not working

Hello,
I am an airsoft player from Spain, and I get to this forum looking for information compressors and how to recharge bottles.
You have been very useful to me, thanks for all the information you share here.

I purchased al Altaros Compressor booster last february 2017.
No issues in the last months to fill paintball bottles i use with my HPA airsoft guns.I use a 200litres deposit, 10Bar, 2 cylinder compressor to feed the booster.
Recently the middle pressure gauge does not go up properly and i did not have output pressure to fill the bottles.In the middle of the cycle you can hear a very noisy "clack".

somebody has experienced the same?

I have changed sylica gel, but that is nt the issue. It seems to cycle between LS and RS.
I have sent an email on friday to ALtaros as the item is in warrranty. But maybe here you have experienced a similar issue and you have some advice

thanks!

Luis
