Buehnen HB 450 Bead Bulk Hot Melt Glue Gun – Pneumatic Industrial Applicator

Pneumatic Bulk Hot Melt Glue Gun for Bead Application

Built for industrial bead dispensing, the Buehnen HB 450 Bead combines pneumatic power with bulk adhesive flexibility for efficient manual application. Its fixed temperature design operates at 376°F (190°C), providing consistent performance without the need for adjustment or operator input.

The HB 450 Bead is compatible with a wide range of hot melt chemistries, including EVA, polyolefins, and pressure sensitive adhesives (PSA), and accepts pellets (granules), pillows, and 43 mm slugs. A pneumatic assist system helps reduce hand fatigue, allowing for smoother, more controlled dispensing during repetitive tasks.

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