RM Series Variable-Speed (n / ne)
Variable-speed oil-flooded rotary screw compressors
RM n and ne variable-speed compressors match output to demand with oil-cooled IE5 permanent magnet motors, cutting energy cost where air demand changes through the day.
Overview
Key Features
- All-new airend with an optimised rotor profile, improving efficiency by as much as 16%
- Fixed-speed models use premium IE3 motors; variable-speed models use oil-cooled IE5 permanent magnet motors, with up to 12–30% energy saving
- Three-stage separation with a conical baffle leaves just 3 ppm of oil in the delivered air
- Luminance controller with high-resolution touch screen, built-in internet connection, automatic alarms and reports, and a sequencer for up to 4 compressors
- Unwelded oil cooler and after-cooler arranged horizontally in parallel on top of the unit, reducing leakage and maintenance
- Integral gearbox and sealed, maintenance-free drive system with strategically placed lubrication points
- Large-allowance air intake with low pressure-drop air filter
- Genuine Ingersoll Rand consumables for life
