What is the purpose of the pressure relief valve in medical air compressor systems?

The purpose of the pressure relief valve in medical air compressor systems is to prevent excessive pressure buildup that could lead to system failure or hazardous conditions. By relieving pressure when it exceeds a specified limit, typically at 50% above the line pressure, the valve ensures that the system operates safely within its designed pressure range. This function is critical in maintaining the integrity of the entire gas delivery system—preventing leaks, ruptures, or other potential risks associated with over-pressurization.

The relief valve acts as a safety mechanism to protect both the compressor itself and the downstream components, allowing them to function without the threat of damage from high pressure. This safety feature is a key component in safeguarding both patients and medical personnel in settings where medical gases are used.
