Buehnen HB 450 Bead Pneumatic Bulk Hot Melt Glue Gun

HB 450 Bead Pneumatic Glue Gun for Bulk Hot Melt Adhesives

The Buehnen HB 450 Bead is a pneumatic bulk hot melt applicator designed for reliable bead dispensing in industrial environments. Built for ease of use and consistent performance, it operates at a fixed temperature of 376°F (190°C) to ensure steady adhesive flow without the need for adjustment.

The HB 450 Bead supports a wide range of hot melt adhesives—including EVA, polyolefins, and pressure sensitive adhesives—and accommodates multiple adhesive forms such as pellets (granules), pillows and 43 mm slugs. Its pneumatic assist reduces trigger effort, improving operator comfort during extended use.

Note: Requires an external air regulator (not included).
