Type-C charging: 5VDC and 1AFeatures

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) Precision vacuum control:

The electric pump can bring the internal pressure down to -30kPa within 40 seconds to create a very strong vacuum seal. You can see deformations occurred to the lid and container body caused by the air pressure.

3) Vacuum indicator:

when completely vacuum-sealed, the center of the vacuum valve will collapse inward from its original dome shape.

4) Long-lasting vacuum:

By using the electric pump, the vacuum level will be about -30kPa every time, which is better than using a manual pump. That means the vacuum seal of your filament container will be kept for a longer period of time and re-pumping will become less frequent.

The pump is powered by a rechargeable battery, and one charge will last 1-2 months for normal use.

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.
