Pressure blasters are tools used for cleaning and surface preparation by propelling abrasive materials at high speeds. They work by using compressed air or water to force the abrasive media, such as sand or glass beads, onto surfaces. This process effectively removes dirt, rust, and old paint, making it popular in industries like automotive and construction. These devices come in various types, including sandblasters and water blasters, each designed for specific applications. Pressure blasters can be portable or stationary, allowing for flexibility in use. Proper safety equipment, such as goggles and gloves, is essential when operating these machines to protect against flying debris.
