The depressor regulates the process of adding carbon dioxide (CO₂) to beverages, ensuring that the desired level of effervescence is achieved and maintained. This is essential for the taste and sensory experience of the consumer.

A well-designed depressor prevents the loss of carbonation during transport and service, ensuring that beverages retain their freshness and quality until consumption.

Integrating a depressor into dispensing systems allows for faster and more consistent beverage dispensing.
