In a medical air supply system, what is required for dryers, filters, and regulators?

In a medical air supply system, having dryers, filters, and regulators arranged in a duplex configuration is essential for ensuring continuous and reliable operation. A duplex setup allows for one unit to remain in operation while the other can be serviced or maintained without interrupting the air supply. This redundancy is particularly important in medical settings, where a consistent supply of clean and dry air is crucial for patient safety and equipment functionality.

The necessity for these components to be duplexed arises from the critical nature of medical applications. If one filter or dryer were to fail or require maintenance, the duplex system ensures that the other unit can take over, thus preventing disruptions that could affect patient care or lead to contaminated air being supplied to sensitive medical devices.

While other options suggest different configurations or placements for these components, they do not provide the same level of reliability and continuity of service that a duplex system offers. Therefore, the requirement for dryers, filters, and regulators in a medical air supply system is best fulfilled by utilizing a duplex configuration.
