Key benefits Reliable, high-volume airflow: the metal trigger with a high-quality PTFE valve assembly delivers strong air volume for faster, more efficient operation. Durable, corrosion-resistant construction: the aluminum-alloy body is polished multiple times and finished with electrophoresis and anti-oxidation treatment for long service life and a precise fit. Easy maintenance and fast repairs: the air-gun core is designed for quick disassembly and can be replaced using a long hex sleeve when the quick-installation fitting is damaged, minimizing downtime. What it does (functions and performance) Designed for sandblasting and surface treatment tasks including glass grinding, sandblasting, surface polishing, and cleaning of mechanical parts. Effective for glass rust-prevention treatments and surface preparation for coatings or painting. Suitable for decorative and fabrication work on items such as aluminum-alloy fixtures and marble lettering, and can also be used in craft applications like flower making. Materials and build Trigger: robust metal construction for reliable actuation. Valve assembly: high-quality PTFE components for smooth operation, chemical resistance, and strong airflow control. Body: precision-machined aluminum alloy, polished multiple times and treated with electrophoresis and anti-oxidation coating to resist wear and corrosion. Practical advantages Faster, easier operation thanks to the strong air output and smooth trigger action. Reduced maintenance time because the core can be quickly removed and replaced with standard tools (long hex sleeve) when the quick-installation component fails. Durable finish and materials help maintain performance in demanding workshop and production environments. Typical use scenarios 1) Glass finishing: use for glass grinding, smoothing, and rust-prevention treatments to prepare surfaces for polishing or coating. 2) Industrial cleaning and preparation: remove scale, contaminants, or old coatings from mechanical parts and prepare metal or stone surfaces (aluminum alloy, marble) for engraving, lettering, or assembly. 3) Craft and decoration work: sandblast or texture small decorative items, prepare pieces for painting, or support floral craft production where controlled air volume and precise finishing are required. Compatibility and handling notes Intended for use in sandblasting, surface polishing, paint preparation, and similar air-driven surface-treatment tasks. Built to integrate with standard compressed-air systems; use appropriate fittings and follow safety guidelines for pressure, media, and protective equipment. Maintenance-friendly design enables quick replacement of the internal core with a long hex sleeve if the quick-installation fitting becomes damaged. This product is engineered to combine strong airflow, durable materials, and easy maintenance for reliable performance in both workshop and decorative applications.
