Condition: new, Pro Sandblaster for Industry Pressure Unit SAPI Mammut Sandblasters with QUICK STOP™ System The SAPI Mammut sandblasters with the QUICK STOP™ system are powerful industrial sandblasting machines, designed for use in industries such as automotive, construction, and manufacturing. These machines ensure fast and efficient surface preparation, cleaning, and treatment of metal, concrete, and other materials. QUICK STOP™ – Safety & Protection The SAPI QUICK STOP™ system is a safety feature designed to prevent accidents and protect the machine from damage. It works by immediately stopping the blasting process as soon as the operator releases the control handle. This instantly cuts off the abrasive flow, preventing potential hazards and protecting the equipment from overuse-related damage. Efficiency & Durability The QUICK STOP™ system reduces air and fuel consumption, making the sandblasting process more efficient and cost-effective. The Mammut sandblasting machine is built for durability, featuring high-quality components that ensure consistent performance, even in harsh conditions. All our machines are fully CE- and TÜV-certified. Flexibility & Versatility The machine is available in different sizes to meet various sandblasting needs. It is compatible with a wide range of abrasive materials, from standard sand to specialized plastic or metallic media. The Mammut with QUICK STOP™ can be used for surface preparation, cleaning, and removing rust, paint, and coatings. Precision & User-Friendliness The Mammut with QUICK STOP™ allows for precise pressure control and adjustment during operation, ensuring consistent results and high accuracy. Additionally, inspection and maintenance access points are designed for easy upkeep. Maximum Safety The QUICK STOP™ system with a dead man’s switch ensures maximum safety during operation. It also prevents moisture buildup inside the machine, as pressure remains constant even when blasting stops—a major advantage over standard on/off blasting systems. Fully Equipped from the Start All Mammut sandblasters with QUICK STOP™ come fully equipped. Our standard package includes: ✔ Sandblasting hose ✔ Nozzle ✔ Pressure control valve ✔ Water separator Pedsupyw Eopfx Aggjpw ✔ Abrasive dosing valve ✔ Basic personal protective equipment
