The Auto Duct Line 3 from HYRUN delivers a complete spiral duct production system in a remarkably space-saving 8-meter footprint, seamlessly integrating coil feeding, precise forming, and automated cutting.
Equipped with advanced servo-controlled spiral forming rollers, the Auto Duct Line 3 consistently achieves superior seam accuracy of ±0.4 mm, ensuring airtight and professional-grade duct quality.
This versatile Auto Duct Line 3 effortlessly processes galvanized steel and aluminum coils ranging from 0.5 to 1.0 mm thickness without requiring any tool changes or reconfiguration.
Operation is simplified through an intuitive 7-inch touchscreen featuring over 20 pre-programmed settings for the most common duct diameters, making the Auto Duct Line 3 ideal for both experienced operators and newcomers.
Energy-Efficient Operation
Compared to traditional manual production lines, the Auto Duct Line 3 consumes up to 30% less power thanks to its intelligent auto-sleep mode and optimized drive system.
Secure galvanized steel or aluminum coils (0.5–1.0 mm thickness) onto the decoiler of the Auto Duct Line 3, ensuring the strip enters the feeding system smoothly and without tension distortion.
Easily select the required duct diameter (80–800 mm) from over 20 built-in preset programs using the intuitive 7" touchscreen of the Auto Duct Line 3, saving setup time and reducing errors.
Once started, the Auto Duct Line 3 fully automates the entire spiral duct production cycle — from precise servo-driven forming to infrared-controlled cutting with ±0.4 mm tolerance — while real-time monitoring ensures consistent quality.
Before running continuous production on the Auto Duct Line 3, always confirm that the emergency stop button and safety light curtains are fully functional to protect operators at all times.
Daily Maintenance
After each shift, clean the spiral forming rollers and lubricate the guide rails according to HYRUN’s recommended 400-hour schedule to maintain peak performance and extend the service life of your Auto Duct Line 3.
