What is the cut-out pressure for air systems?

The cut-out pressure for air systems is the pressure at which the compressor stops running to prevent over-pressurization of the system. In many applications, including those relevant to fire protection and VCFD practices, the cut-out pressure is typically set to 130 psi. This value is established to ensure a safe operating margin, allowing for adequate control of the air delivery system while preventing potential damage due to excess pressure.

In the context of air systems used for firefighting or emergency response, having a standard cut-out pressure like 130 psi helps maintain efficiency and safety. It also ensures that when pressure exceeds this threshold, the compressor will cease operation, allowing pressure to stabilize before any further air is delivered into the system. Thus, the correct cut-out pressure for air systems aligns with common industry practices that prioritize both operational reliability and safety.
