Walt — Simple Man Takeaway
Air is invisible, but a leak is still a load. Find the loss before you blame the cylinder.
Plain-English Summary
Use this flow when a pneumatic machine becomes weak, slow, inconsistent, noisy, or unstable because compressed air pressure or flow is not reaching the point of use correctly. Compressed air problems often disguise themselves as bad valves, weak cylinders, bad sensors, timing faults, or machine hesitation.

Field Checks
- Confirm the symptom
- Measure at the point of use
- Compare static vs. dynamic pressure
- Find obvious losses
- Check the FRL
- Check peak demand
- Check valves and restrictions
- Separate air from mechanics
Watch Out For
- Pressure checked only at compressor, not point of use
- Static pressure looks good but collapses during motion
- Leaking fittings treated as normal background noise
- Plugged mufflers or exhaust restrictions
- Water/oil contamination in the FRL
- Multiple air users starving the same branch
- Mechanical drag being blamed on air supply
Reverse-Trace / Ghost Busting™ Decision
if the valve is not being commanded and the failure is visible live in logic.
if the valve command, pressure switch, or cylinder feedback drops only briefly and recovers before maintenance arrives.

Walt says STOP! - Safety First
Make these checks prior to proceeding.
Stop and follow site procedures when stored air pressure can cause sudden motion, air lines can whip, loads can drop, guards are open, or lockout/tagout is required. Never assume an air circuit is safe because the machine is stopped.
