Chamber Vacuum Sealers

Chamber vacuum sealers are among the most versatile machines for vacuum packaging, delivering results that other types of sealers cannot match. They are especially effective for sealing powders and liquids, achieving low oxygen levels that help preserve product quality.

These machines are also very easy to operate—simply close the lid to begin the cycle, with no foot pedal required. Because the seal is completed before the lid opens, they consistently produce smooth, uniform seals without wrinkles.

Chamber sealers are ideal for delicate or high-value products that require a strong vacuum without being crushed or damaged. Since both the product and pouch are placed inside the chamber, pressure changes occur evenly inside and outside the package. Combined with gas flushing, this process creates ultra-low oxygen environments while protecting items like cannabis, baked goods, and other sensitive products.

High Quality Chamber Sealers for All Applications

IMPAK offers two different lines of chamber vacuum sealers, the Castle Vak series and the Gramatech series.

Benefits of Using a Chamber Vacuum Sealer:

• Greater vacuum percentage (lower oxygen) as compared to a nozzle type sealer
• A longer seal bar (or more than one) allows operators to vacuum seal multiple pouches at the same time, resulting in greater productivity
• Little to no operator involvement after the lid has been closed and the cycle has started
• Options for percentage vacuum will allow for partial vacuum if making an object immobile is your goal
• The vacuum pump is built-in so you don't need any additional equipment

Need Something Custom?

Our Intelligent Sealing System is the solution for custom sealing equipment. iS² chamber sealers offer a higher degree of control, as well as a more convenient touch screen interface, plus the option to store multiple recipes. The iS² system does not come pre-installed on chamber vacuum sealers; this is an upgrade and begins with a call to our machinery specialists so they can assess your needs and offer a custom system. Generally, we suggest the iS² system for larger units and do not offer it on smaller units unless by unique requirement. The upgrade pricing to the iS² System will depend on your specific needs. Learn more about the iS² System.

Interesting Uses for Chamber Sealers:

Vacuum Packaging Military Supplies

Many branches of the military vacuum package a variety of products, from survival parkas and sleeping bags to mission ready kits for the Navy Seals as well as ammunition and aircraft electronics. In some cases, the vacuum packaging is done for space reduction purposes, where in other cases it is for dry-packing the product for long term storage. In some cases, like ammunition, it is done to greatly reduce the oxygen in the package, as exposure to oxygen has a detrimental effect on the performance of ammunition that has been in long term storage.

Vacuum Packaging Whole Goat Carcasses for Further Processing

This project was a good example of both the versatility and superior performance that can be achieved with vacuum chamber machines. This product needed to be vacuum sealed with equipment that would provide for extremely low residual oxygen content in the finished package. It also required a seal system that could handle an extremely large bag and needed to be simple enough to be operated by mostly untrained operators in rural environments. While large nozzle-type machines could handle the large bags, they could not produce end results that meet the low residual oxygen requirement, and were more difficult to achieve the best seal results with. Since the throughput required was low to medium, a custom-sized single chamber vacuum sealer was the best choice.
