An Air Eraser / Tire Buffer is a pneumatically powered rotary tool designed for surface cleaning, texturing, and preparation on rubber, metal, or other materials.It uses compressed air to spin a small abrasive head or buffing wheel at high rotational speeds, allowing operators to remove paint, rust, oxidation, or rubber residue, or to roughen surfaces for better adhesion during repairs. This tool is commonly used in automotive workshops, tire retreading plants, metal finishing, and surface treatment operations, where precision and speed are required in small areas.
