Description
The Bühnen HB 450 Spray is a professional pneumatic-assisted handheld spray hot melt applicator designed for straightforward, reliable adhesive application in industrial environments. Operating at a fixed temperature of 190°C (376°F), the HB 450 Spray provides simple, consistent performance for applications that do not require adjustable temperature control.
The versatile melt tank accommodates hot melt adhesives in granule, pillow, or 42 mm cartridge formats, providing flexibility across a variety of production and assembly applications. Its ergonomic grip, balanced weight distribution, and pneumatic-assisted operation make the HB 450 comfortable to handle during repetitive use.
The standard 1.5 mm conical swirl spray nozzle provides controlled spray application, making this model well suited for applications requiring adhesive coverage over a wider surface area than a traditional bead.
