Top Considerations for Designing Vacuum Chambers

You probably think of large vessels that are useful in the storage of vacuum when in high pressures. Well, that is true, but these vessels come in different configurations like the hydraulic separator.

A vacuum chamber is essential in product testing, as you can create atmospheric conditions in the chambers. You can also use other accessories to improve the functionality of these vessels. It is not a must that you get the ready-made chambers; you can always opt to have them custom-made to suit your application.

But, what are the critical features in the design of this equipment?

Surface Finish

The chamber should have a clean surface finish on the outside while the inner surface should have a lining of a non-porous material.

Structural Features

The strength of the chamber is a product of the total structural components in place. The incorporation of structural components, such as stands, lifting points, and hinges, are useful in the overall strength and reliability of the chamber.


There is no rule that limits the shape that the chamber must take. However, the most common shapes are cylindrical, circular, rectangular, and spherical. Your intended application and preference will dictate the shape that you will go for.

Material Choice

The material choice is probably the most important decision you will make for your vessel. Suitable materials in the building of these structures are carbon steel and stainless steel due to their high strength and robustness. Avoid using materials that are of poor quality or are too porous on the inside.

A vacuum chamber is a useful equipment in numerous industrial applications such as product testing, vacuum sealing, vacuum drying, and vacuum encapsulation. Aside from the hydraulic separator, ensure that you get the right accessories for the maximum benefit of your vacuum chambers.
