Esun Vacuum Kit Pro (10 bags, 1 Pump, allochroic desiccants)

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

1. Vacuum-sealed storage:
   An electric pump removes air from the sealed plastic bag around the filament spool, reducing moisture exposure.

2. 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.

3. 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.

4. Compact, reusable, and portable:
   The kit is small, easy to handle, and the bags can be reused many times
   

How to Use It

1. Dry your filament spool in a filament dryer or oven first for best results.

2. Put the spool, desiccant, and humidity card in the vacuum bag; seal using the clip.

3. Use the pump to evacuate the air, ensuring a strong seal.

4. Store in a cool, dry place until next use
