Understanding Modulator Wear and Repair Service

A spray-paint can: If the spray nozzle clogs or if the paint-can lacks a solid spraying mechanism, the targeted canvas surface may end up with blotches of paint. Comco’s modulated feed produces a steady mixture of air and abrasive that prohibits clogs, clumping, bursts of abrasive, sparse mixtures, etc. The steady stream of abrasive produces a uniform and repeatable surface finish. A salt shaker:  the technology of other blasters relies on a series of components that is similar to a salt shaker. They shake abrasive out into the air stream, and that means an unreliable amount of abrasive exits the nozzle. Comco’s blasters feature a modulator that pulses consistently, pulling the same amount of abrasive particles into the abrasive stream with every pulse.
