eSUN eVacuum Kit Pro 3 – Filament Vacuum Storage & Sealing System

Description

eSUN eVacuum Kit Pro 3 – Keep Every Filament Print-Ready

Moisture is the silent killer of 3D printing. Filaments like PLA, PETG, TPU and Nylon absorb humidity straight out of the air, and the damage shows up in your prints as stringing, popping and bubbling at the nozzle, weak layer bonding and rough surfaces. The eSUN eVacuum Kit Pro 3 solves this by sealing your spools in an airtight, vacuum-locked environment – so every roll prints as well as the day you opened it.

Key Features

• Upgraded electric air pump – pulls a strong vacuum in seconds for a tight, reliable seal.
• One-button start – effortless, mess-free operation with no manual pumping.
• BPA-free & FDA compliant – food-grade, safe materials you can trust.
• eBOX compatible – pairs with the eSUN eBOX for the best drying-and-storage results.
• Wide compatibility – fits standard 1 kg filament spools from most brands.
• Reusable bags – seal, unseal and re-seal the same bag every time you swap a spool.
• Compact & convenient – a lightweight kit that stores neatly on any workbench.

What’s in the Box

• 10 × reusable vacuum-seal filament storage bags
• 1 × upgraded electric air pump
• Sealing valves & accessories

Why Filament Storage Matters

Even a few hours on an open shelf lets hygroscopic filament soak up moisture from the room, and in Indian humidity that happens faster than most people expect. Vacuum-sealing with the eSUN eVacuum Kit Pro 3 removes the air that carries that humidity, extending shelf life and protecting your print quality. It is the cheapest insurance you can buy if you order filament in bulk, keep a lot of colours on hand, or print only occasionally and leave spools sitting between jobs.

Which Filaments Need It Most

Every filament benefits, but some are far more sensitive than others. Nylon (PA) and PVA are the worst offenders and can turn unprintable within a day of open-air exposure. TPU and PETG take on moisture quickly enough to cause visible stringing and surface defects. PLA and ABS are more forgiving, but still lose surface finish and layer strength over weeks in an open room. If you run engineering materials at all, sealed storage stops being optional, and the eSUN eVacuum Kit Pro 3 is the simplest way to get it.

How to Use the eSUN eVacuum Kit Pro 3

Drop the spool into one of the reusable bags, close the seal, place the pump over the valve and press the button. The pump draws the air out in seconds and the bag collapses tight around the spool. When you want to print, unseal the bag, take the spool out, then re-seal it for the next roll – the bags are built to be used again and again, not thrown away.

Dry First, Then Seal

Vacuum storage stops new moisture getting in; it cannot pull out moisture that is already in the plastic. If a spool has been sitting open for a while, run it through a filament dryer first, then vacuum-seal it with the eSUN eVacuum Kit Pro 3 to lock that dryness in. Dry, then seal – that order is what keeps filament genuinely print-ready.

Frequently Asked Questions

Does the eSUN eVacuum Kit Pro 3 work with any filament brand?

Yes – the storage bags fit standard 1 kg spools from most brands, not just eSUN.

Do I still need a filament dryer?

Vacuum storage prevents new moisture absorption. For filament that is already damp, dry it first with an eSUN eBOX or a filament dryer to remove the existing moisture, then vacuum-seal to keep it that way.

Is the air pump manual or electric?

It uses an upgraded one-button electric air pump – no manual pumping required.

Are the bags reusable?

Yes. The kit ships with 10 reusable vacuum-seal bags, so you can open and re-seal the same bag each time you swap spools.

Is it safe to store filament in these bags long term?

The bags use BPA-free, FDA-compliant food-grade material, so they are safe for long-term storage.
