Description
The eSUN eVacuum Kit Pro (also known as eVacuum Kit Pro 2 or Pro 3) is used for storing 3D printer filament to protect it from moisture, dust, and degradation. Here's how and why it matters:
Why moisture protection matters
-
Many filaments (like PVA, Nylon, ePA, TPU, PETG, ABSMAX, etc.) are hygroscopic, meaning they absorb water from humid air.
-
Moist wet filament can cause issues like bubbling, poor layer adhesion, stringing, brittle prints, or nozzle clogs.
-
Keeping filament dry helps maintain print quality and material integrity
What the Kit Does
-
Vacuum-sealed storage:
An electric pump removes air from the sealed plastic bag around the filament spool, reducing moisture exposure. -
Desiccant packs + humidity indicator:
You place a silica gel pack and a humidity card inside the bag to absorb any residual moisture and monitor levels. Indicator cards can be reactivated in an oven to reuse. -
Food-grade, double-sealed bags:
The BPA-free, FDA-grade PE+PA bags offer a tight dual-zip seal for air and moisture protection. They're sized for 0.5–1 kg filament spools in 1.75 mm, 2.85 mm, or 3 mm variants. -
Compact, reusable, and portable:
The kit is small, easy to handle, and the bags can be reused many times
How to Use It
-
Dry your filament spool in a filament dryer or oven first for best results.
-
Put the spool, desiccant, and humidity card in the vacuum bag; seal using the clip.
-
Use the pump to evacuate the air, ensuring a strong seal.
-
Store in a cool, dry place until next use
