HVAF High Velocity Air Fuel Surface Grit Blasting Coating Application Applied Coating
ArcMaster 300™

The ArcMaster 300 is a dependable high-performance twin-wire arc spray system designed for reliable and cost effective deposition of a full range of metal coatings from solid or cored wides of 1.6-2.3 mm dia (1/16"-3/32").

The spray gun is durable, lightweight, and utilizes a powerful pull mechanism which helps maintain a consistent coating quality during spraying. The lightweight and robust one-piece polymer frame of the gun contains just a handful of additional metal parts, making it simple to operate and service.

ArcMaster 300 is also available in a high feed rate (HFR) configuration that is optimized for materials with low melting points, such as zinc and aluminum.
