What is a common symptom of a leaky pneumatic system?

• A. Rapid bursts from actuators.
• B. Immediate overpressure protection.
• C. Slow actuator response, lag, and fluctuating pressure.
• D. No effect on performance.

Answer: (C)

A leak in a pneumatic system mainly shows up as a compromised air supply that the actuator can’t rely on. When there’s a leak, air escapes from the lines, fittings, or seals, so the pressure available to drive the actuator drops and isn’t steady. That loss of pressure means the actuator doesn’t receive enough force promptly, so movement is slower and there’s a noticeable lag between when you command the action and when the actuator completes it. The regulator and compressor may cycle to try to maintain pressure, which can cause the line pressure to bounce up and down, producing fluctuating readings. In short, the system feels “soft” and slow, with pressure that isn’t stable. The other scenarios don’t reflect how a leak behaves: a leak doesn’t typically cause rapid bursts, it’s not about immediate overpressure protection, and obviously a leak degrades performance rather than leaving it unchanged.
