What Is A Chamber Vacuum Sealer?

A very common question for us to receive is: “What is a Chamber Vacuum Sealer?”

Today, we will answer that question simply!

A chamber vacuum sealer distinguishes itself from a regular vacuum sealer by removing all the air in the pouch & chamber vac itself, resulting in a completely airtight seal for your product.


Initially, the air pressure around us and the air pressure inside the chamber of the chamber sealer are exactly identical (14.7 psi at sea level). A vacuum is created inside the chamber vacuum sealer which in turn creates an airtight seal. Depending on the vacuum pump quality, up to 99.8% of the air is then removed from the chamber sealer and vacuum pouch. Once all the air is extracted from the chamber, the vacuum pump shuts off and the bag is sealed.

Up to this point, it will appear as though no air has been removed from the vacuum pouch. The pressure inside the pouch is equal to the pressure in the chamber vacuum sealer. After the bag is fully sealed off, a valve will open to reintroduce air back in. The process will continue until pressure is equal to the environment outside the chamber. During these few seconds is when the bag will tighten up around the product. Finally, the vacuum-sealed look will be observed in this final process.

How does the sealing process work?

The air inside is first evacuated out of the chamber vacuum sealer machine. Once the chamber vac machine removes the air from the chamber entirely, it then recycles the air into the seal section. The air is re-exerted or recycled under the seal bar lift pistons forcing the bar up while simultaneously heating the seal wire (heat strip) up. The more air you remove, the more powerful the seal.

Three very simple reasons why you should stay with a chamber vacuum sealer machine.

1) Initial cost of a regular vacuum sealer (external) may be lower, but chamber vacuum pouches/bags are 3-5 times cheaper than the textured bags and roll.

2) Secondly, the life span and longevity of a chamber vacuum sealer far exceeds the cheaper suction, edge, and external vacuum sealers.

3) Lastly, your packaged goods will stay fresh much longer due to a chamber vacuum sealer’s ability to remove more air. Most chamber vacuum sealers will remove at least 99% of air, compare to only 80% for even a good quality external vacuum sealer. Dispose of those oxygen absorbers as a high-quality chamber vacuum sealer eliminates the presence of oxygen, leaving nothing for them to absorb.
