Air Hooper Gun SMT-FR300

The SMT-FR300 is a heavy-duty air hopper gun built for thick, textured, and coarse materials that standard spray guns cannot handle. With three interchangeable nozzles (4.0mm / 6.0mm / 8.0mm) and a powerful 21 CFM air demand, it delivers fast, consistent coverage for stucco, plaster, acoustic coatings, and architectural renders on large surfaces.

✅ 3 nozzles: 4.0 / 6.0 / 8.0mm
✅ 21 CFM high-volume air flow
✅ 600ml gravity-feed cup
✅ 3.5 Bar / 50 PSI pressure
✅ 1/4″ standard air inlet
✅ Heavy duty industrial build

Ideal for textured plaster, stucco, acoustic coatings & architectural renders. Requires a compressor rated at 25 CFM or higher for peak performance.
