The airlock Filament Vacuum Sealing System was designed by Judd from polyalchemy Filament and is an incredible product that Phaser FPV use in their print farm and 3D Printer setup.
Phaser FPV recommendations
Dry your filament with the Sunlu Filament Dryer & use it while printing with a Dryer Mount. You can monitor the humidity in the Sunlu Dryer with our Humidity Sensor & Humidity Mount When printing is finished, store it in the airlock bags and remove air with NanoVac Pump. You can then place a Humidity Sensor in our spool adapter and have a good gauge of humidity on the spool when you go to print again. It may require drying again for optimal results however it won't take as long because of the storage in the bags. You can even stack all your filament on top of each other once they are in the airlock bags. Be careful of any sharp filament ends and certain spools that have sharp areas as this can puncture the bags.
