High capacityWith internal dimensions of 450 x 210 x 211 mm, the SUNLU FilaDryer S4 can simultaneously dry four 1kg filament coils.Moreover, it is equipped with eight filament holes and PTFE hoses.The S4 thus meets the user's requirements for multi-color printing and printing on multiple computers.Rapid heatingThe built-in 300 W PTC heater heats up to 50 °C in 30 minutes faster and more efficiently. The PTC heating element has a heating power of 330 W, WAS corresponds to a 6.9-fold increase as compared to the SUNLU FilaDryer S2. The maximum heating temperature is 70°C.3 security levels- PTC (positive temperature coefficient thermistor),- Temperature switch and triple software protection,- Real-time temperature monitoring- Alarm messages at abnormal temperature for greater safetyTemperature compensationThree circulating fans (on the left and right side and the lower fan heater) in the housing ensure that the temperature in the housing of the FilaDryer S4 is balanced to ±3 °C and that each part of the consumables can achieve a perfect drying effect.Adjustable air humidityAdjust the humidity in the housing. When the humidity in the box reaches the set value (30% - 50%), it starts automatically until the humidity drops to 25% and then stops to better meet the moisture requirements of different types of consumables.High compatibilitySupports all printer models connected to use; supports simultaneous printing of four 3D printers.The SUNLU Filadyer S4 has pre-configured temperature settings for commonly used filaments such as PLA, ABS, PETG, TPU, PA and PC. These configurations are based on test data and provide optimum drying time and temperature. By expanding the options while reducing setup complexity, we want to improve your experience.The filament dryer is compatible with the following filament diameters of 1.75 mm, 2.85 mm and 3.0 mm.This text is machine translated.
