OSHA regulations require remote controls on all abrasive blast machines. Pneumatic remote control systems operate efficiently with up to 100 feet of twinline control hose. Electric remote control systems operate efficiently at distances up to 500 feet. For distances greater than 300 feet, special remote control cable is required.
Pressing the remote control handle activates the system and starts blasting; releasing the handle stops blasting. When the handle is released, a spring-loaded lever mechanism keeps the handle from accidentally activating the system.
Electric remote controls use an electric cord and micro-switch in place of the twinline hose and orifice used in pneumatic handles. Electric handles operate on 12 volts.
