SKU CH-PMV0-V5Z1Y

Keeps 20 spools dry and dust-free in 34×30 cm vacuum bags with a hand pump included

  • Protects filament from moisture and dust with vacuum sealing
  • Includes hand pump for easy air removal without power
  • Multi-layer composite bags are reusable and recyclable
  • Secure clip chain locks each bag with one pinch
  • Twenty 34×30 cm bags store multiple spools at once

Filament Storage Kit for Moisture Protection

This set includes twenty vacuum bags measuring 34x30cm and a hand pump sized 140x30mm. The bags are made from multi-layer composite plastic designed to shield PLA, TPU and ABS filaments from moisture, dust, insects, mould and odour. The kit keeps consumables in optimal condition for printing and can be reused many times.

Upgrade from Open Spools or Zip Bags

Standard resealable bags and loose spools allow humidity to degrade filament over time, causing brittleness and print defects. These vacuum bags remove air with the included hand pump, creating a low-moisture environment that prevents oxidation. The switch is worthwhile when you store multiple spools for weeks or months between prints.

Simple Hand-Pump Operation

Each bag uses a bite-in clip chain that locks with one pinch, and the hand pump extracts air without electricity or fittings. The pump measures approximately 5.51x1.18in and the bags 13.38x11.18in, so they fit on most shelves. Common issues are incomplete sealing if the clip is not fully pressed and gradual air ingress if the valve is not checked periodically.

Questions about this item

What size are the vacuum bags and will they hold a standard filament spool?

Each bag measures 34 by 30 centimetres, or 13.38 by 11.18 inches, which accommodates typical 1 kg spools of PLA, TPU or ABS filament.

How do I use the hand pump and clip chain to seal a bag, and what step do people often miss?

Place the spool inside, press the bite-in clip chain closed with one pinch, then attach the pump nozzle to the valve and pump until the bag compresses tightly around the spool; the step often missed is ensuring the clip chain is fully locked before pumping.

How long do the bags and pump last, and what part will need replacing first?

The multi-layer composite bags are recyclable and reusable many times; the hand pump, at 140 by 30 millimetres (5.51 by 1.18 inches), is the component most likely to wear out after repeated use.
