About this item

• Four-Spool Filament Dryer Box - SUNLU S4 is the first filament dryer box capable of accommodating four 1kg spools simultaneously. It is equipped with eight filament holes and PTFE tubes, meeting the demands for drying multiple filaments and enabling concurrent printing with multiple printers.
• Auto Humidity Monitoring - The SUNLU FilaDryer S4 features a precise humidity sensor for monitoring interior humidity levels in real time. In standby mode, the dryer will kick in automatically if interior humidity hits 50% or higher, guarding against excess moisture. This functionality allows it to double as a filament storage container.

This reduces setup complexities and enhances your user experience.
