Remote control systems give an operator the ability to remotely activate and deactivate the flow of air and abrasive at the nozzle. Pressure-release remote control systems pressurize and depressurize the abrasive blasting pot each time the operator activates and deactivates the remote control switch, allowing for the abrasive blasting pot to be filled between activation cycles.  Pressure-hold remote control systems are ideal for high production applications where an operator is frequently activating and deactivating the remote control switch during operator re-positioning. The pressure-hold remote control system allows the vessel to remain pressurized when the remote control switch is deactivated. This eliminates the time waiting for the vessel to depressurize and pressurize, increasing production rates.
