Which type of compressor can introduce oil into the medical air system if not configured correctly?

Reciprocating compressors are commonly used in medical air systems, and their operation involves the use of oil for lubrication. If these compressors are not configured properly, there is a risk that oil could be carried over into the medical air supply. This is particularly concerning in medical applications where the purity of air is critical for patient safety. The oil contamination can occur during periods of increased pressure or improper maintenance, leading to impaired air quality that can affect both equipment performance and patient care.

Unlike diaphragm and scroll compressors, which typically operate in a manner that minimizes or eliminates the potential for oil contamination, reciprocating compressors rely on lubrication to function effectively. Proper maintenance and configuration are essential to ensure that the oil is contained and not released into the medical air system. Liquid ring compressors, while also featuring lubrication, utilize a different mechanism that inherently reduces the risk of oil carryover compared to reciprocating types.
