SUNLU FilaDryer S4 is the world's first large-capacity filament dryer box, featuring extra-large space, high efficiency, safety, and uniform temperature distribution.

1. Large Capacity
Internal dimensions: 450 × 210 × 211 mm, capable of drying up to 4 rolls of 1kg filament simultaneously, meeting multi-color printing and multi-printer usage requirements.
2. Rapid Heating & Efficient Drying
Equipped with a 350W PTC heater, heats up to 70°C for fast drying of specialty filaments such as PA and PC, improving workflow efficiency.
3. Triple Safety Protection
PTC thermistor, mechanical temperature switch, and software monitoring provide three levels of protection. Real-time temperature monitoring triggers alerts in case of anomalies, ensuring safe operation.
4. Temperature Uniformity
Dual side circulation fans combined with a bottom heating fan maintain chamber temperature within ±3°C, ensuring even drying for every filament roll.
5. Intelligent Humidity Control
Automatically adjusts chamber humidity. Starts when humidity reaches the set range (30%-50%) and stops when it drops to 25%, preventing filaments from reabsorbing moisture.
6. High Compatibility
Compatible with all printer models, supports simultaneous filament feeding for up to 4 printers, and works with filament diameters 1.75 mm, 2.85 mm, and 3.0 mm.
