Vacuum Storage Set Vacuum Kit is specially designed for vacuum sealed storage, to keep filament dry and increase the service life of your 3D printer filament, because damp 3D printer filament leads to stringing, clogging, poor adhesion and layer shifting, which may directly affect your printing effect.
Improved Sealing EffectVacuum Kit is designed with double seal zipper and heavy-duty valve for easy pump and sealed protection. And the sealing ring is made of a softer silicone material, which can bond better to the valve area when vacuuming. Microporous vacuum storage bag allows maximum air removal, which enables better moisture-proof and dust-proof effects.
USB Electric PumpVacuum storage bags can be connected to the USB Electric Pump to make for an airtight fit. Compared with hand pump, it can provide you with faster speed and stronger power while saving your efforts to pull air out.
Eco-Friendly and ReusableVacuum Kit is made of food-grade PEPA composite material, which is durable and reusable. And it has passed BPA-FREE and FDA certification, making it environmentally friendly and safe to use. Vacuum storage bag has better moisture-proof effect to those moisture sensitive filaments.
