What is the cut-in pressure for air systems?

The cut-in pressure for air systems refers to the minimum pressure level at which a compressor begins to operate and supply air to the system. It is crucial for ensuring that the system functions reliably and effectively. In many pneumatic systems, the set cut-in pressure is typically around 85 psi, as this level is considered optimal for initiating compressor activity without causing premature cycling or operational difficulties. This specific setting helps maintain consistent pressure levels in the system, preventing issues such as inadequate air supply or overworking the compressor.

While other pressures may be used in different systems or contexts, 85 psi is widely recognized as the standard cut-in pressure in many industrial and commercial air systems, making it the correct choice in this scenario.
