Product Description

The Filament Vacuum Bag Kit (with Auto Pump) is a practical set of vacuum bags specially designed for keeping 3D printing filaments dry and dust-free. The package includes an automatic (electric) vacuum pump, allowing you to vacuum the air out in seconds – without manual pumping.

The bags are made of multi-layer barrier film, featuring an integrated extraction valve and a reliable zip closure. Combined with the included silica gel bags and humidity indicator cards, you get an effective and affordable solution to protect your spools from moisture and ensure consistent print quality.

This type of kit is commonly used by brands like Yoopai or Amolen and is compatible with most standard spools (0.5–1 kg).

Main Advantages

• Moisture Protection – vacuum bags significantly limit the access of air moisture to the filament, ideal for hygroscopic materials (PETG, Nylon, TPU, PA-CF, etc.).
• Auto Vacuum Pump – the electric pump extracts air quickly and effortlessly, just place it against the bag valve.
• Increased Print Quality – dry filament means less stringing, bubbles, matte surfaces, and other defects caused by water in the material.
• Universal Use – compatible with PLA, PETG, ABS, ASA, Nylon, TPU spools, and others in common weights of 0.5–1 kg.
• Reusable Bags – durable material and a high-quality zip allow for repeated use without significant loss of airtightness.
• Organization and Storage – easy labeling and organized storage of filaments, less clutter around the printer.
• Multipurpose Use – the bags can also be used for vacuum storage of other sensitive materials if needed.

Package Contents (Typical Set)

Exact contents may vary slightly depending on the specific variant; a standard set usually includes:

• 10–20× vacuum bag for filament with valve (for 0.5–1 kg spools)
• 1× automatic (electric) vacuum pump
• 10–20× desiccant bag (silica gel)
• 5–10× humidity indicator card
• 2× sealing clip for easy zip securing
• Instruction manual

Features and Use

1. Inserting the Filament Place the filament spool into the vacuum bag, add the desiccant bag and optionally the humidity card.
2. Closing the Bag Carefully close the zip using the included clip – this prevents air leakage during extraction.
3. Vacuuming Place the automatic pump on the bag valve and turn it on. After a few seconds, the bag is under vacuum and the filament is safely protected.
4. Moisture Check The humidity card inside the bag indicates by color whether the environment is still dry – if the color changes, simply replace the desiccant and vacuum the air again.
5. Reuse After removing the filament, the bag can be reused as long as the material remains undamaged and the valve seals properly.

Key Benefits for 3D Printers

• Fewer failed prints and saved filament by eliminating moisture in the material.
• Better surface quality of prints and more stable mechanical properties.
• Simple and fast operation – ideal even for beginners.
• Compact solution without the need for large dryers or boxes.
• Long-term protection even during longer storage of rarely used materials.

Recommendations for Use

• For materials like Nylon, PETG, TPU, PC, PVA and other highly hygroscopic filaments, vacuum storage is highly recommended.
• After opening a new spool, always return it to the vacuum bag with a fresh desiccant after printing.
• Store bags away from direct sunlight and high temperatures to prevent degradation of the bag plastic.

The Filament Vacuum Bag Kit (with Auto Pump) is a great choice for anyone who wants to maximize filament lifespan and achieve stable printing results without unnecessary complications.
