Auto-Feed Vacuum System automatically administers adhesive into a connected hot melt tank to avoid any loss of time or additional labor costs associated with typical manual refilling operations. The auto-feed system offers operator safety and time-efficiency to your production floor.Auto-Feed Vacuum System Constant refilling avoids charring of the adhesive in the tank for maximum productivity and quality gluing. Non-direct labor contact ensures a safer working environment. Complete elimination of adhesive waste, spillage and contamination. Reduces thermal impact in the hot melt tank. Filter guarantees a dust-free environment for the unit's tank. An illuminating light sensor offers visual confirmation of filling action. Venturi feed process can transport adhesive chips up to 5/8" in diameter See Flyer
