Belated Happy New Year, Everyone!
Ambush Paintball runs on CO2 as a norm but has always supplied air in some form on organised training events (H-Pac in October and bulk cylinders for the Nexus Seminar late November). There is no reason for that to change.
If you are booking one of our fields for a private training session, we will not normally provide air (at the moment!). However, if you want us to get a bulk cylinder in for you and you give us enough notice - it could be arranged, for a fee (I would need to double check the costs).
I hope that helps??
