The CAC-A system operates at a regulated air pressure range. Which range below matches typical operation?

• A. 80-100 psi
• B. 40-60 psi
• C. 120-140 psi
• D. 20-40 psi

Answer: (A)

Understanding how a CAC-A system uses air helps explain why this range is standard. The system relies on a regulated air supply to power its pneumatic components, so the pressure must be high enough to move actuators and valves reliably, but not so high that it stresses seals or triggers safety limits. About 80 to 100 psi hits that balance well: it provides solid, responsive performance for the tooling without pushing parts beyond their intended limits. Pressure ranges that are too low, like 40–60 psi or 20–40 psi, tend to be sluggish or unreliable—actuators may lag or stall. A pressure range that’s too high, such as 120–140 psi, risks unnecessary wear, potential leaks, and may exceed what the system components are designed to handle. So 80–100 psi is the most appropriate and typical operating window for consistent CAC-A performance.
