When storing unused consumables in vacuum bags, manually pressing the bag with a small vacuum pump for several minutes can be quite labor‑intensive. To address this, we’ve designed this handy accessory to free up your hands and make the process more efficient. The accessory is compatible with vacuum pumps that have a diameter of approximately 50 mm—simply slide it into the slot at the top. To start pumping, turn the top knob clockwise until it securely seals the suction port, then flip the switch on the top to activate the pump. Once the bag is fully evacuated, simply turn the knob counterclockwise to release the seal and remove the bag.
