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.
Fast Heating & Drying Evenly – The SUNLU S4 filament dryer is equipped with a PTC heating element and a triple-fan configuration. The interior heat is efficiently circulated with three fans, making the heating process more even. Additionally, the S4 filament dry box achieves rapid heating up to 70 °C in record time. The robust 350W PTC heater is 6.9 times more powerful than the SUNLU S2, ensuring an accelerated and efficient filament drying experience.
Auto Humidity Control – The SUNLU FilaDryer S4 incorporates a high-precision humidity sensor, displaying real-time interior humidity. Even when the filament dryer is in standby, it will automatically activate when the interior humidity reaches or exceeds 50%, preventing secondary moisture exposure. Thus, it can also serve as your filament storage box.
Easy to Use – The adjustable temperature range is 35°C to 70°C, with a setting time from 0 to 99 hours. This 3D printer filament dryer features a large touch screen, providing a tablet-like operation experience. It also comes with pre-configured temperature and drying time settings for commonly used filaments such as PLA, ABS, PETG, as well as PA and PC. This reduces setup complexities and enhances your user experience.
Universal Compatibility – The SUNLU S4 filament dehydrator is compatible with PLA, PLA+, PETG, TPU, ABS, PA, PC, Nylon, and other high-end 3D filaments. It works perfectly with all standard filament diameters: 1.75mm, 2.85mm, 3.00mm.
