What is installed in each header of central supply systems to prevent debris from entering the manifold controls?

In central supply systems for medical gases, a filter is installed in each header to effectively prevent debris from entering the manifold controls. The purpose of the filter is to capture particulate matter, which can include dust, rust, and other contaminants that may be present in the gas supply before it reaches sensitive components of the system, such as the manifold controls.

By ensuring that only clean gas enters the manifold, the filter plays a critical role in maintaining the integrity and functionality of the medical gas supply system. This protective measure helps to enhance the safety, reliability, and performance of the system, ultimately benefiting the health care environment where these gases are utilized.

The other components mentioned, such as check valves, monitors, and relief valves, serve different functions within the system, such as ensuring unidirectional flow, monitoring pressure levels, and preventing overpressure, respectively. However, they do not specifically address the contamination issue associated with debris, making the filter the correct choice for this particular requirement.
