Q: What is the maximum vacuum pressure guaranteed by the pump (in kPa)?
A: The pump is guaranteed to achieve a maximum vacuum pressure of -40kPa.
Q: What is the power rating of the pump motor (in W)?
A: The pump motor has a power rating of 17W.
Q: What is the expected lifespan of the manual hand-held vacuum food sealer (in hours)?
A: The unit has an expected lifespan of approximately 232 hours.
Q: What is the maximum number of continuous vacuum and seal cycles the vacuum machine can perform before requiring a cool-down period or experiencing reduced suction performance?
A: The vacuum machine can complete 70–100 continuous vacuum and seal cycles (varies by vacuuming duration). The heated motor has little impact on the cycle count; vacuuming a 2.2L container takes 22–24 seconds, and there is minimal drop in suction performance.
Q: What is the diameter of the handheld unit's suction port?
A: The suction port of the handheld unit has a diameter of φ49 (49mm).
Q: Is the manual hand-held vacuum food sealer equipped with a recessed gasket to ensure a consistent, full seal over the bag's valve each time?
A: Yes. It is designed with a recessed gasket, and the recessed silicone rubber gasket also stops the vacuuming process automatically when the fluid tank is full or nearly full.
Q: What material is used for the gasket/sealing ring?
A: The gasket/sealing ring is made of silicone rubber.
Q: What is the battery capacity of the vacuum machine (in mAh)?
A: The unit has a battery capacity of 1500 mAh.
Q: How many full vacuum/seal cycles can the vacuum machine complete on a single charge?
A: On a single charge, the vacuum machine is rated for 70–100 full vacuum/seal cycles.
Q: How does the unit clearly indicate that the full vacuum level has been reached and the seal is complete?
A: The Handheld vacuum sealer will automatically stop operating once the vacuuming process is completed, indicating the full vacuum level is reached and the seal is done.
Q: What is the specific material of the reusable bags?
A: The reusable bags are made of PA + PE (Polyamide + Polyethylene).
Q: Are the reusable bags certified food-grade, BPA-free, and safe for sous-vide cooking (boil-safe) and freezing?
A: Yes. The reusable bags are certified food-grade, BPA-free, and safe for both sous-vide cooking (boil-safe) and freezing.
Q: What accessories are usually included with the hand-held vacuum food sealer?
A: The standard accessory package includes: 1 hand-held vacuum food sealer, 1 charging cable, 2 sealing clips, and 30 vacuum bags (2 sizes: 15 medium bags of 8.27" x 8.66" + 15 large bags of 10.24" x 11.02").
Q:Why does some water flow out after pumping?
A:This is because the first stop occurs when the water storage tank reaches its maximum water level, leaving residual water in the bag and at the air valve port unextracted. If you continue vacuuming after draining all water from the bag, the residual water at the air valve port will be pumped away.
Q:What is the external hose used for?
A:the external vacuum hose is equipped to drain liquid during multiple consecutive pumping operations. Without this hose, continuous pumping will cause water to overflow. A 26*28CM air valve vacuum bag typically requires 3-4 pumping cycles to completely extract all liquid and achieve a full vacuum.
