Product detailed description
The 75 kW at ten bar gives 13,700 l/min. Regulation goes all the way down to 2,900 l/min, 21 % of output — the lowest floor anywhere in the range, and on a machine this size that counts.
Why 10 bar
Ten bar means 13,700 l/min against 16,300 at seven, a drop of 16 %. In exchange the regulation range stays the widest in the range: the machine will come down to a fifth of its output without having to shut off.
| The same 75 kW machine at three pressure settings | |||
|---|---|---|---|
| Order code | Pressure | Free air delivery (l/min) | Loss against 7 bar |
| SCR-75/7EPM2 | 7 bar | 3,800 – 16,300 | 0 % |
| SCR-75/8EPM2 | 8 bar | 3,600 – 16,000 | 2 % |
| SCR-75/10EPM2 — this machine | 10 bar | 2,900 – 13,700 | 16 % |
The dimensions of 2,280 × 1,500 × 1,950 mm, weight of 2,010 kg, DN 65 outlet and noise level of 78 dB(A) are identical across all three settings — it is one and the same machine.
How it differs from its neighbours
The smaller SCR-63/10EPM2 gives 12,000 l/min, the larger SCR-90/10EPM2 16,500 l/min in the same frame. If less pressure would do, the same machine as the SCR-75/7EPM2 adds 2,600 l/min.
What is inside
Permanent magnet motor
Oil cooling in a closed circuit, IP65 protection, a design with no bearings. On 75 kW a saving of 5–6 % against IE2 is a figure you can see in the budget.
Direct drive through a taper coupling
No belts and no gearbox. On 75 kW a slipping belt would mean a loss of output that nobody notices until the electricity bill arrives.
Frequency inverter
Instead of blowing off the excess it reduces speed: 2,900 to 13,700 l/min steplessly, a floor at 21 % of output, pressure still within ±0.1 bar.
New-generation airend
A reground rotor profile and optimised ports. On a machine giving 13,700 l/min, every percent of efficiency means a different sum than it would on a small compressor.
SCR9000 controller
A graphical schematic of the machine, a service schedule and remote monitoring over RS485. A cascade of sixteen machines with no separate control cabinet.
What the machine needs in the compressor room
Thirteen thousand seven hundred litres a minute is 822 m³/h. That volume sizes the dryer and the filtration, and at ten bar a dryer is effectively mandatory. The compressor room ventilation has to handle 17,500 m³/h, otherwise the machine will run hotter and shut down sooner than you expect.

Equipment
- permanent magnet motor above IE4 level, oil-cooled in a closed circuit, IP65 protection, no bearings
- direct drive through a taper coupling — no belts, gearbox or coupling
- vector-controlled frequency inverter, regulation across 25 to 100 % of speed
- the cooling fan is inverter-driven as well
- new screw airend with a rotor profile developed in Japan, service life over 100,000 hours
- SCR9000 controller with touchscreen, weekly schedule and cascade of up to 16 machines
- intake nanofilter with 99.9 % retention, 0.1 µm oil filter
- oversized separator holding residual oil below 3 ppm
- all-steel internal pipework instead of rubber hoses
- soft start — the current never exceeds the rated value
The combination of high pressure and a wide regulation range suits plants where demand falls almost to nothing overnight. The material you need to decide is in the SCR-EPM2 range; condensate is dealt with by the dryers in the air dryers.
When your plant goes quiet overnight, this machine will not cycle. On the larger classes that floor sits a third higher.
