The tank is a Pure Energy Basics 4,500 psi, 68 ci. The regulator is preset somewhere between either 800-850 or 800-900 psi, depending on which web site you believe...
Yep, that will work, plus the EXC even with the expansion chamber does not have that much internal volume, so compressed air output of 850+ will work good. Just a note though...Other VM-68s with huge expansion chambers have too much internal volume for compressed air. In the past, internal volume on the VMs was created to control the pressure spikes with CO2 which made the velocity super nasty.
