About Filadryer SP2[2-in-1 Filament Dryer and Storage Box Combination]Is there any way to handle drying and storage filament at the same time? SUNLU FilaDryer SP2, with efficientheating baseandstorage box, designed as two separated parts. Multiple storage boxes can be used as storage boxes can be freely stacked (maximum stacking of 3 is recommended) to enhance space utilization.
[Strong Sealing]The top cover and sealing bottom cover are designed with silicone, which has a good sealing effect. Whether used as a filament dryer or as a storage box, it has very good thermal insulation. When used as a storage box, it has been measured that under an average ambient humidity of about50%, an average of about25%humidity can be maintained inside.
[Large Internal Space and Spool Compatibility]Internal compatibility with 0.25~3kg spools, even paper spool can also be realized by fixing the spool roller. The storage box compartment can hold two rolls of1kg filaments, one roll of 2kg (2 rolls of 2kg filaments for SUNLU), and 3kg filaments, and supports a maximum spool diameter of 250mm and a maximum spool width of 153mm. it is compatible with both 1.75mm and 2.85mm diameter filament. Even damaged spools can be fixed with the spool roller.
[Humanized Design]The storage box part adopts the detail design of carrying handle + bottom depression, which is convenient for users to move. In addition, the storage box is equipped with anindependent hygrometerfor real-time observation of internal humidity changes, and 3 cable outlet holes on each side of the box to meet the printing needs of different sizes of filaments.
[Strong Safety, Stress-free Use]The triple safety design of 200W PTC + fan heating, secondary temperature protection switch and software intelligent temperature control ensures the heating process is foolproof. Modular Design
