eSUN eVacuum Kit Pro 2-US 10 bags 33 x 38cm 3d printers accessory

Filament vacuum kit for FDM printers

The eSUN eVacuum Kit Pro 2-US provides an electronic vacuum storage system designed for 3D printing filament. It includes ten upgraded vacuum bags, an electric pump, two sealing clips and fifteen discoloration desiccants. The kit supports simultaneous storage of ten spools and suits hobbyists or small workshops needing to keep hygroscopic materials dry.

Humidity resistance limits for hygroscopic filaments

Bags use a dual-colour bilateral seal and single-side embossed design to resist dust and moisture for materials such as PVA, PA, PA-CF, PA-GF, ABS, MAX and TPU-95A. The colour-change desiccants turn pink when humidity rises, signalling that the desiccant needs replacement. Protection lasts only while the seal remains intact and the desiccant stays active.

Simple setup with common sealing checks

Place the spool in a 33 x 38 cm bag, close the zipper fully with the supplied clip, set the valve on a flat surface and attach the electric pump. Most failures come from an incompletely closed zipper, a tilted valve or poor pump-to-valve contact; re-sealing the zipper or repositioning the valve usually restores vacuum. Bags are BPA-free food-grade PE+PA composite and also suit food storage.
