My only concern would be that your water pressure isn't high enough. In commercial systems, the air pressure is at 90-120psi, but the water pressure usually at a minimum 250psi (and sometimes as high as 900psi).
When the water pressure drops below the air pressure, you get what we called "the helicopter", where the snowgun pulses and makes a "whomp whomp whomp" sound (like a helicopter).
I have always assumed this is happening because the air and water are "fighting" each other and instead of getting a constant stream of mixed air/water you are getting a period of water only, then a period of air only. The snowgun will actually bounce up and down. We'd run into this a lot when trying to turn down the water really low on days where the temperatures were very marginal.
I have heard of people using pressure washers to up their water pressure.
