The SUNLU S4 Filament Dryer is designed to provide optimal drying conditions for various 3D printing filaments. Key features include:

• Gran capacidade: Accommodates up to four 1KG spools simultaneously, enabling multi-color or multi-machine printing without interruption.
• Quecemento rápido: Equipped with a 350W PTC heater, the S4 heats from 25℃ to 50℃ in approximately 30 minutes, ensuring efficient drying.
• Uniform Drying: Three built-in fans (two circulating on sides, one on bottom) maintain a temperature balance within ±3℃ for consistent drying throughout the box.
• Triple Security: Features PTC, temperature switch, and software protection for enhanced safety and real-time temperature monitoring.
• Smart Auto Humidity Control: Allows users to set a desired humidity range (30%~50%). The dryer automatically starts drying when humidity exceeds the set range and stops when it falls below 25% to prevent over-drying.
