Graco 24P307 InvisiPac GS35 Single Hot Melt Applicator with No Solenoid and Ni 120 RTD

Graco GS35 Single Hot Melt Applicator for Packaging Equipment

The Graco 24P307 InvisiPac GS35 is a single hot melt applicator configured without an onboard solenoid, designed for constant bead dispensing in case and carton sealing applications. As a plug-free hot melt adhesive applicator, it helps eliminate nozzle plugging and reduce adhesive char, supporting consistent adhesive flow and improved uptime in continuous packaging operations. Its free-flow manifold design and integrated applicator filtering minimize dead zones where char can accumulate, helping maintain clean, low-maintenance performance.

The applicator incorporates a Ni 120 RTD for accurate temperature monitoring and reaches operating temperature in under 10 minutes, allowing production lines to start quickly. When used with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 delivers clean, stable adhesive flow throughout the dispensing system. With air-opened, spring-closed operation and cycle speeds up to 3,500 cycles per minute, this single-module GS35 is well suited for high-speed industrial packaging and continuous manufacturing adhesive applications.
