Basic Abrasive Blast System Equipment Basis blast system equipment consists of the following components: A large capacity air compressor to furnish a clean, dry, high-volume compressed air supply. A large air pipe/hose to convey the high-volume compressed air to the equipment. A blast machine that stores an adequate supply of abrasive and mixes the high-volume compressed air and abrasive in the correct proportions. A large blast pipe/hose to convey the high-volume, abrasive air mixture from the blast machine to the work area. A blast nozzle equipped with ON/ OFF remote safety controls so that the operator(s) can control and direct the high-speed (up to 500 miles per hour), high-volume jet of abrasive air mixture emerging from the nozzle. The jet is aimed at the surface to be cleaned or etched and, under the force of impact, the abrasive cuts, loosens, and carries away substrate surface contaminants such as paint, dirt, oil, oxidation, etc. Depending on the hardness and impact force of the abrasive, a portion of the substrate surface may also be removed. Operator protective gear and either a breathing air compressor or breathing air pump with a breathing air filter and carbon monoxide detector or converter to provide an air supply for personal and respiratory protection and comfort during blasting operations. To the average person, abrasive blasting appears to be a simple operation with reasonably uncomplicated equipment. However, every component of abrasive blast system equipment must be specifically designed and selected to carry out its function. Each component is important to the overall operation and safety of the system. Neglecting to learn about the strengths and limitations of the equipment can result in hampered blasting operations and/ or hazards to the operator.
