Graco 24P299 InvisiPac GS35 Single Hot Melt Applicator with 24 VDC Solenoid and Ni 120 RTD

Graco GS35 Single Plug-Free Hot Melt Applicator for Packaging Lines

Designed for consistent constant bead adhesive output, the Graco 24P299 InvisiPac GS35 single hot melt applicator delivers reliable adhesive flow for case and carton sealing operations that require stable, uninterrupted dispensing. Its plug-free design helps eliminate nozzle plugging and reduce adhesive char, supporting improved uptime and cleaner operation. A free-flow adhesive path with integrated filtering minimizes dead zones where char can accumulate, helping maintain dependable performance in continuous packaging environments.

The applicator features a 24 VDC solenoid valve for responsive actuation and a Ni 120 RTD for accurate temperature monitoring during production. When used with the Graco InvisiPac Tank-Free Hot Melt Delivery System, including HM10, HM25c, and HM50 models, the GS35 provides clean, stable adhesive delivery throughout the dispensing system. With a heat-up time of under 10 minutes, air-opened, spring-closed operation, and cycle speeds up to 3,500 cycles per minute, this single-module GS35 is well suited for constant bead applications in packaging automation and industrial packaging equipment.
