Try amazon. Cheaper.

Psi is the pressure per square inch so the point of the regulator is to reduce the psi from the paintball tank or CO2 tank(800-1000psi) to around a useable range (0-60psi).

Regular ceramic diffusers only need 10 psi but if you're using atomic diffusers from GLA or Up Aqua, you'll need above 30 psi which can be adjusted on the regulator.
