What method is used to seal a vault by utilizing air pressure?

The method used to seal a vault by utilizing air pressure is known as an Air Seal. This technique relies on creating a strong barrier that prevents outside elements from entering the vault, specifically by using air pressure to maintain a seal. In an air-sealed vault, the design ensures that air cannot penetrate, which protects the contents from moisture, pests, and other potential hazards.

This method is particularly important in funeral service merchandising as it ensures the preservation of caskets and other items held within the vault. The ability to use air pressure for sealing provides a reliable means of safeguarding items in a way that other sealing methods, such as a water seal or vacuum seal, may not achieve in the same capacity. Understanding the air seal method is crucial for those in the funeral service industry, as it directly impacts product quality and longevity.
