SPT 140 Oil Mist Separator Test System
Automated blow-by oil-mist separator test system for gravimetric and fractional separation efficiency, pressure-flow characteristics, pressure regulation and leakage under conditioned aerosol operation.
Model Overview
| Model | System purpose | Standards / method | Core fit |
|---|---|---|---|
| SPT 140 | Automated test bench for flow, pressure, leakage and gravimetric/fractional separation performance | Application-specific blow-by separator methods | Crankcase-ventilation separator development, benchmarking and validation |
Key Features
Gravimetric separation efficiency
Measures separated and downstream oil mass across defined volume-flow conditions.
Fractional efficiency option
Supports size-resolved oil-droplet removal-efficiency characterisation.
Pressure and flow regimes
Tests separators in overpressure and underpressure modes with controlled flow.
Pressure-regulation curves
Records crankcase-system pressure against intake pressure at multiple flow rates.
Leakage measurement
Evaluates separator and oil-drain leakage as part of the complete performance assessment.
Conditioned oil-mist generation
Uses a heated oil-mist generator up to 120 °C with mineral or synthetic engine oils.
