Basics
What is vacuum packaging?
Vacuum packaging — also called vacuum packing or cryovacing — removes the air from the bag and the food before it is sealed. Less oxygen means perishable food keeps much longer in the fridge, freezer or pantry. External sealers like every LAVA work with embossed bags and rolls; smooth bags are for chamber machines.
How do I find the right vacuum sealer for me?
Compare all models side by side on the Vacuum Sealers page, or call us on 1300 77 88 29 — we recommend the machine you need, even if it is the smaller one.
Can I use any foil?
Almost any foil up to 200 microns works in an external LAVA sealer, as long as it is embossed (structured) on one side: the channels let the air out. Smooth bags, like the G-Vac, are made for chamber machines only.
Can I vacuum seal liquids?
Small amounts are fine on models with a double or triple seal. For soups, sauces and large batches, chill or freeze first or use vacuum containers — the suction attachment is included with your sealer.
Can I use third-party bags and equipment?
Often yes, as long as bags and rolls are made for external sealers. Performance is not guaranteed, so we recommend original LAVA bags and rolls.
Troubleshooting
The vacuum bag does not vacuum
- Place the bag opening below the stop bar, flat and without folds.
- Smooth bags must be at least 120µm thick.
- On a new machine, press the lid firmly for the first cycles.
- Close the L+ pressure regulator.
- Clean the gaskets.
The machine does not seal automatically
- Clean the gaskets.
- Set the switch to Automatic (the V.100 is manual only).
- Close the L+ regulator and check the liquid separator cover.
- If the machine has drawn in a lot of liquid, contact our service team.
The machine does not reach full vacuum
- Clean the gaskets and the bag opening.
- Check the liquid separator and the L+ regulator.
- Avoid sharp edges that puncture the bag — use bone protection.
- Use bags that are thick enough.
- After a large liquid intake, contact service.
The machine cannot be switched on
Check the power outlet, cable and plug. If the machine or cable is damaged, do not use it — contact our service team.
A bag made from a roll draws air again
Cut the roll, seal one side first in automatic mode, then fill the bag and vacuum it.
The seal is not clean
- Clean the sealing bar.
- Replace worn seal (welding) tape — available as a spare part.
- When sealing, place the roll only on the seal tape.
A vacuum container draws air again
Clean the valve and seals thoroughly and remove the suction attachment without touching the valve cover. LAVA lids were tested for about 25 days, but we recommend storing for up to 10 days.
Service
Can I service my vacuum sealer myself?
Yes — many wear parts such as seal tape and gaskets are plug-in and user-replaceable. The parts finder on the Spare Parts page shows which ones fit your model, or call us for help.
How do I make a warranty claim?
Contact us first by phone or email with your order number. All warranty cases are return-to-base. See Warranty for details.
Self-service
Replace seal tape & gaskets yourself
Plug-in wear parts, no tools needed. Choose your model and see which seals and tape fit.
