Do dryers, filters, and regulators in medical air systems need to be at least duplexed?

In medical air systems, it is not a requirement for dryers, filters, and regulators to be duplexed. Duplexing refers to the use of two units operating in parallel to ensure redundancy and reliability. While duplexing is common in critical systems for enhanced safety and continuity, standards do not mandate that every component, such as dryers, filters, and regulators, must be duplexed.

Using a single unit for these components can be sufficient, as long as they meet the necessary performance specifications to ensure the air quality and pressure requirements for medical applications. In many cases, the design and configuration of these systems depend on the particular medical facility's needs, existing infrastructure, and operational protocols. Therefore, a system can function effectively with single units without the need for duplexing, as long as it is compliant with the relevant regulatory standards and guidelines for safety and quality in medical gas delivery.
