### Air Quality Assessment

Compressed air analysis revealed particle contamination levels 10 times higher than acceptable limits for pneumatic systems. The existing filtration system was inadequate for the fine wood dust particles that easily passed through standard filters.

### Cylinder Design Evaluation

Heritage’s existing cylinders lacked environmental protection features essential for dusty environments. Standard rod seals and inadequate rod wipers allowed contaminants to enter the cylinder bore, causing rapid seal degradation and scoring.

### Contamination Pathway Analysis

We identified five primary contamination routes: atmospheric infiltration through inadequate seals, compressed air supply contamination, maintenance-introduced particles, ambient dust settling on exposed components, and [electrostatic attraction](https://www.sciencedirect.com/topics/engineering/electrostatic-attraction)[2](#fn-2) of fine particles to cylinder surfaces.

### Environmental Monitoring Results
