PrintDry Vacuum Sealed Filament Container Set of 5 with Electric Pump

PrintDry vacuum sealed filament container is the ultimate filament storage solution for 3D printing filaments to prevent the filament from absorbing moisture. 5 vacuum containers are included. Container overall size 265 (OD) x 115 (H) mm (10.5″ OD x 4.5″ H) Filament spool size (max) 205 (OD) x 85 (H) mm (8″ OD x 3.3″ H) Electric Pump Lithium Battery: 1200mah Type-C charging: 5VDC and 1A 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) 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…
