What is the basic definition of a Sandblast Gun?

A Sandblast Gun, or "sandblasting gun," is the core component of sandblasting surface treatment equipment. It consists of a gun body, nozzle, air inlet, and media inlet. Connected to an air compressor, it generates a high-pressure airflow of 0.4-0.8 MPa, spraying media such as quartz sand and corundum at high speed onto the workpiece surface to remove rust, degrease, engrave, or roughen the surface.

What are the common types of Sandblast Guns?

Based on their function, they are divided into three categories: suction-type (negative pressure type), which features a simple structure and low cost, suitable for manual sandblasting of small workpieces (such as hardware rust removal); pressure-feed (positive pressure type), which uses a pressure tank to pressurize the media, offering high force and efficiency, suitable for large workpieces (such as steel structures and ship hulls); and specialized types, such as micro-sandblasting guns (for cleaning precision parts) and wet sandblasting guns (for reducing dust), which are suitable for specific applications.

What safety precautions should be taken when using a Sandblast Gun?

Personal protection must be taken: wear a dust mask or gas mask (to prevent inhalation of dust), impact goggles (to prevent media splashing into the eyes), wear-resistant gloves (to prevent scratches), and protective clothing; select the medium according to the material of the workpiece (such as glass beads for glass to prevent scratches), and adjust the pressure from low to high; work in a closed and ventilated sandblasting room to avoid dust diffusion. Clean the medium and check the nozzle wear after the work.
