PrintDry Vaccum Container (5 Pack)

To prevent the filament from absorbing moisture
The ultimate filament storage solution for 3D printing filaments
Include: 5-pack with a vacuum pump (Filament spool not included)

Features
1) Vacuum valve and pump:
A special valve and a pump are used to suck the air out to create a vacuum seal and this will prevent the moisture in the air from getting into the container.

2) Stronger structure:
Both the lid and the container have been specially designed to hold a strong vacuum seal.

3) Vacuum indicator:
when completely vacuum-sealed, the center of the vacuum valve will collapse inward from its original dome shape.

Testing
The vacuum filament container has been tested with a 750g filament spool inside for 30 days. The graph below shows the changes of the relative humidity (grey line) inside the container and the ambient humidity (red line) as the storage time increases. Five pouches of 15g desiccant are included in the container.
