Vacuum Chambers Explained

VacuumChambers

Vacuum Sealers remove oxygen from a package prior to sealing the bag.  By removing oxygen from the package, vacuum sealing can extend the life of a food package or prevent rust of industrial items.  Our vacuum chamber sealers require no external compressor and can vacuum seal liquids and powders.  Depending on the bag size, vacuum chamber sealers can also vacuum seal multiple bags at a time.

Learning how a vacuum chamber works may be less intuitive than a nozzle vacuum sealers so we created a quick little infographic to walk you through the mechanics of a vacuum chamber.

  1. Bag is placed in a vacuum chamber sealer.  The open end of the bag should go over the sealing bar.
  2. Vacuum pump removes oxygen from the vacuum chamber including the oxygen inside the bag.  The pressure in the chamber is now lower in the chamber than outside.  Because air rushes out of the chamber more quickly than in the bag, this can cause the bag to puff up inside the chamber (pressure in bag is higher than chamber for a short amount of time).  This is normal.
  3. Vacuum sealer seals the bag closed.
  4. Vacuum sealer then allows the chamber to equalize.  This allows the pressure of the chamber to be the same inside and outside of the chamber.  The bag (because it is sealed) cannot equalize the pressure along with the rest of the chamber.  As a result the atmospheric pressure in the chamber causes the bag to collapse and thus vacuumed.

As a result of this method, vacuum chambers are able to vacuum seal liquids in bags and provides an advantage over nozzle vacuum sealers.
