Comgrow Filament Dryer Box, SH02 Filament Dehydrator with PTC Fast Heater and Touch Screen, 3D Printer Filament Sealed Storage Box with 2 Spools Holder Compatible with PLA PETG TPU ABS 1.75/2.85mm

Comgrow SH02 Filament Dryer Box is an innovative 2-spool holder filament dehydrator designed to streamline 3D printing workflows with its high-efficiency drying capabilities and user-friendly features. Equipped with two strategically positioned filament holes compatible with PTFE tubes, this dryer accommodates various extruder configurations across different 3D printers, offering universal compatibility for seamless integration into any setup. Its large capacity allows simultaneous drying of two 1KG filament spools, making it ideal for users managing multiple printers or diverse filament types while optimizing workspace efficiency. Powered by a robust 150W PTC heating system, the SH02 rapidly achieves temperatures up to 70°C, reaching 50°C in just 7 minutes and full operational temperature within 25 minutes, ensuring quick preparation for printing tasks. The advanced 360° hot air circulation system, driven by a built-in fan, ensures uniform heat distribution for thorough moisture removal from materials like PLA, ABS, PETG, and specialty filaments, directly enhancing print quality by preventing bubbling, stringing, and layer adhesion issues caused by moisture. Beyond drying, its reinforced airtight construction with multiple sealing rings and thickened materials functions as an effective storage solution, maintaining filament dryness between uses. The intelligent one-touch control panel simplifies operation with pre-programmed settings for nine filament types—including PLA, TPU, PETG, ABS, ASA, PVA, PC, PA, and PP—each optimized with manufacturer-recommended temperature and drying durations up to 98 hours, eliminating guesswork for both novice and experienced users. Safety is prioritized through multiple protection mechanisms: the system automatically cuts power if PTC temperatures exceed 130°C and reactivates when cooling below 90°C, while an audible alarm alerts users to fan malfunctions, preventing overheating risks. Energy-efficient PTC technology minimizes power consumption without compromising performance, making it a cost-effective solution for continuous operation. With its compact yet durable design, the SH02 combines rapid drying cycles, dual-spool capacity, and smart automation to reduce downtime, enhance printing consistency, and protect filament investments, establishing itself as an essential tool for hobbyists and professional makers seeking reliable moisture control in demanding 3D printing environments.

• 2 Spools Holder Filament Dehydrator: Comgrow SH02 filament dryer box is equipped with 2 filament holes which allow PTFE pipes through. The newly designed filament hole position is convenient for 3D printers with different extruder positions on the market. Large capacity of drying 2 rolls of 1KG filament at the same time meets the needs of users to dry a wide range of filaments and two printers at the same time, saving space and time.
• Maximum Temperature Up To 70℃: SH02 adopts 150W PTC heater which can heat up faster and are more energy-efficient. Temperature range:40-70℃.The maximum temperature is 70℃.SH02 dryer box can reach 50°C within 7 mins and reach 70°C within 25 mins. The dryer quickly heats with a built-in fan, circulating hot air 360° for uniform heating, effectively drying moisture filaments and improving your 3D printing results.
• A Great Fialment Storage Box: We use thicker sealing materials with stronger sealing performance and add several sealing rings around the box to keep drying. Multiple protections to prevent filaments from getting wet.
• One Key Set for 9 Types of Filaments: SH02 has one-key temperature setting for 9 different types of 3D Printing filaments, including PLA, TPU, PETG, ABS, ASA, PVA, PC, PA, PP. We have set default drying temperature and time for each type of filaments in advance. Just press one key to choose the filament type and the drying box will start working as you expected immediately.The maximum drying time is 98H.
• Intelligent Safety Protection: When PTC temperature exceeds 130°C, it will automatically cut off the heating, and when the PTC temperature drops below 90°C, it will automatically resume heating. If the fan stops rotating during use, an alarm will sound to prompt you to replace the fan to prevent the PTC module from burning out.
