ELGI Neuron II compressor: a worn unit became more efficient without teardown
Current draw under load decreased, air pressure increased, no repair was required. 8–10.3 % — motor current under load, 35.1–35.8 → 32.1–32.3 A; 6.1 % — air working pressure at idle, 4.9 → 5.2 bar (2019).

Key results
| EQUIPMENT | CONDITION AT THE START OF TESTING | WHAT WAS MEASURED |
|---|---|---|
| ELGI Neuron II / 30 HP screw air compressor, direct drive; electric motor 22 kW | In service since 2012; elevated oil temperature, noise and vibration, longer air pump-up time due to considerable wear of parts | Motor current on all three phases and air working pressure — before treatment and after 50 h of operation |
Motor current draw under load
| PHASE | BEFORE TREATMENT, A | AFTER 50 H, A | CHANGE |
|---|---|---|---|
| Phase I | 35.8 | 32.1 | −10.3 % |
| Phase II | 35.6 | 32.1 | −9.8 % |
| Phase III | 35.1 | 32.3 | −8.0 % |
| Total over three phases | 106.5 | 96.5 | −9.4 % |
The reduction was reproduced on all three phases. In the report summary, power consumption is stated as reduced by 10 % on average.
Air working pressure
| MODE | BEFORE TREATMENT, BAR | AFTER 50 H, BAR | CHANGE |
|---|---|---|---|
| Idle (Unload) | 4.9 | 5.2 | +0.3 bar (+6.1 %) |
| Under load (Load) | 6.3 | 6.4 | +0.1 bar |
The rated working pressure of the compressor is 0.7 MPa (7 bar).
