Meler SF4 Hot Melt Adhesive Melter, 1.05 Gallon Unit

Compact, Plug-and-Play Hot Melt Adhesive System for Manual and Low-Volume Packaging Applications

The SF4 is a compact hot melt adhesive melter designed for manual and low-volume packaging applications where simplicity and reliability are essential. With a 1.05 gallon tank and a melting capacity of up to 13 lbs/hr, it supports intermittent use and lower adhesive demand, making it ideal for small packaging lines, point-of-use systems, and manual operations. Its gear pump design delivers consistent adhesive flow for bead and swirl applications while maintaining stable operating conditions.

Engineered as a plug-and-play adhesive dispensing system, the SF4 prioritizes ease of use, quick setup, and simplified maintenance. The system provides consistent temperature control to help maintain adhesive viscosity and reduce material degradation over time. With support for two hose outputs and accessible internal components, it offers dependable performance for packaging processes that require flexibility without unnecessary complexity.
