Pneumatic System Parts
Components that prepare compressed air and convert it into motion — quietly responsible for a large share of intermittent machine faults.
Component families
Typical Components
The exact configuration depends on your machine model. Your spare parts documentation — issued per machine — lists the qualified items for your serial number.
| Component | Role in the system | Condition to watch |
|---|---|---|
| Air preparation unit (FRL) | Filters and regulates the supply | Filter saturation, drain function |
| Cylinders | Provide linear motion | Seal leaks, slow motion |
| Solenoid valves | Direct air flow | Response, coil condition |
| Fittings & tubing | Route compressed air | Leaks, brittle tubing |
| Vacuum generators (where fitted) | Hold product during transfer | Filter condition, suction performance |
| Silencers / mufflers | Reduce exhaust noise | Clogging |
Condition & Replacement
Condition-based — per your machine manual.
- Air pressure and the preparation unit are checked daily — drain moisture and verify pressure within the documented range.
- Audible leaks at quiet moments are the fastest pneumatic diagnosis there is.
- Cylinder seals and valve response are inspected in the preventive round per the manual.
Technical Note
Replacement criteria and seal kits are defined per machine in your Path Pack documentation. Air supply problems also block machine start — see Machine Will Not Start; the daily routine lives in Daily Maintenance.
Identifying a Pneumatic Part
Valves and cylinders carry nameplates.
- Machine model and serial number
- Nameplate / part number on the valve or cylinder, photographed
- Position on the machine (which function the component drives)
See Before Requesting a Part for the full checklist.
