Table
Model Total Height Compatible Power Key Differences
4930152131 200mm 22kW/30HP Short version; low flow rate (4.5 m³/min)
4930152101 230mm 37kW/50HP Standard version; universal fit for 6–8 m³/min
4930155571 230mm 37–55kW Extended filter layer; high flow rate for heavy-duty models
Replacement Indicators
Air compressor discharge contains oil; lubricating oil consumption increases significantly
Oil separator differential pressure alarm; insufficient discharge pressure
Service life exceeds 4,000 hours; immediate replacement recommended
