706 uses a pony scuba tank
Last about 30-40 shots.
The tank cost us something like $120 but with that we get free refills. We had to get a supplier to build a custom valve to handle the 1/8 hose. That feeds into a storage tank that holds
60psi. We usually shoot at something between 20 to 40 psi.
With this set up and how fast the scuba tank recharges the storage tank we can shoot all 10 of our stored t-shirts in something like 15-20 seconds.
