Sunlu FilaDryer S4 – a modern filament dryer with an intelligent heating system

The Sunlu FilaDryer S4 filament dryer is a modern device designed for 3D printer users who want to keep their filaments in perfect condition. Thanks to its large capacity, intelligent heating system, and advanced humidity control functions, the S4 guarantees optimal conditions for drying and storing consumables, always ensuring the highest quality 3D prints.

Large capacity and fast heating

Internal dimensions of 450 x 210 x 211 mm allow for the simultaneous drying of four rolls of filament, each weighing 1 kg, which is ideal for multi-color printing and printing on multiple devices. The built-in 330W PTC heating element reaches 50°C in just 30 minutes, with a maximum temperature of 70°C, ensuring fast and efficient drying of filaments, significantly reducing print preparation time.

Triple Safety Protection and Uniform Temperature

The Sunlu FilaDryer S4 offers triple safety protection. The real-time temperature monitoring system is based on three levels of protection (PTC, temperature switch, software protection), ensuring safe operation of the device. An integrated three-fan system (two circulating and one heating fan at the bottom) maintains a stable temperature throughout the device with a precision of up to ±3°C, ensuring even drying of filaments and preventing them from overheating or drying out.

Automatic humidity control and high compatibility

The automatic system adjusts the humidity level within a range of 30%-50%, stopping the drying process when the humidity drops to 25%, guaranteeing ideal conditions for various types of filaments. The device supports all 3D printer models and allows for simultaneous use of four devices. It is compatible with filaments with diameters of 1.75 mm, 2.85 mm, and 3.0 mm (PLA, PET, PET-G, HIPS, ABS, ASA, NYLON, BVOH, nGen, TPU, FLEX, PC, BendLay, PC/ABS, and others), which ensures its versatile use.

Built-in operating modes and a convenient display

The FilaDryer S4 dryer has built-in operating modes, such as a timer (timed drying) and stand-by mode. The 6.4-inch LCD screen provides a clear overview of all settings and operating parameters, making it easy to use. Power is supplied via a 24V DC power supply, which guarantees stable operation of the device.
