The MP741B is a high-precision 1.3mm HVLP suction-feed automotive spray gun engineered for smooth clearcoats, high-gloss topcoats, and fine finishing. Operating at 2.0 Bar with an air consumption of 4.0–5.0 CFM, its HVLP air cap generates a soft spray envelope that breaks clearcoat into fine micro-droplets. Equipped with a 750ml aluminum suction cup and brass air cap, it offers extended paint supply for factory-grade auto refinishing.
