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. This increases productivity and eliminates the need for a pot tender. The Blastmaster® 125P and 123P Remote Control Systems are a pressure-release remote control system that uses a pneumatic signal from the remote control switch to remotely activate and deactivate an abrasive blasting pot. Typical applications include blast rooms, blast yards, bridges, oil refineries, pipelines, railcar shops, shipyards, and storage tanks.
