Oil‑Injected Rotary Screw Compressor SLV7.5‑22 – A Compact Powerhouse from SMEATON
When it comes to reliable, low‑maintenance air supply, the oil‑injected rotary‑screw compressor remains the work‑horse of modern industry. SMEATON’s SLV7.5‑22 series pushes the technology a step further with integrated permanent‑magnet drive and air‑cooling, delivering high efficiency in a compact footprint. Below we break down why this family of compressors is a smart choice for everything from small‑batch manufacturing to large‑scale automation.
SMEATON has built a reputation for robust, energy‑saving compressors that meet the toughest ISO and CE standards. The SLV line benefits from the company’s 30‑year legacy in oil‑injection technology, combined with the latest permanent‑magnet motor design for lower electricity consumption and quieter operation.
| Model | Motor Power | Volume Flow (FAD) | Discharge Pressure | Cooling Method | Permanent‑Magnet Frequency* |
|---|---|---|---|---|---|
| SLV7.5‑22‑7.5 | 7.5 kW | 0.65 m³/min | 7 bar | Air‑cooled | 50 Hz |
| SLV7.5‑22‑11 | 11 kW | 1.20 m³/min | 9 bar | Air‑cooled | 50 Hz |
| SLV7.5‑22‑15 | 15 kW | 2.30 m³/min | 11 bar | Air‑cooled | 50 Hz |
| SLV7.5‑22‑22 | 22 kW | 4.01 m³/min | 13 bar | Air‑cooled | 50 Hz |
*Frequency refers to the mains supply frequency driving the permanent‑magnet motor (standard 50 Hz; compatible with 60 Hz in selected markets).
Key take‑away: The SLV7.5‑22 family covers a broad power range while keeping the volume‑flow ratio consistent, making it easy to scale capacity without redesigning the whole pneumatic system.
| Advantage | What It Means for You |
|---|---|
| Improved Lubrication & Cooling | Oil injection protects the screw pair, reduces wear, and transfers heat away from the compression chamber. |
| Higher Efficiency | The permanent‑magnet motor eliminates the need for a separate starter, cutting idle power draw by up to 30 %. |
| Compact Air‑Cooling | No water‑chiller required; the built‑in air cooler keeps the unit small and maintenance‑free. |
| Low Noise | Oil injection dampens mechanical noise, while the motor’s smooth torque curve reduces vibration. |
| Extended Service Life | SMEATON’s sealed crankcase and high‑quality oil pump extend overhaul intervals to 20 000 hours. |
SMEATON’s SLV7.5‑22 series blends tried‑and‑true oil‑injection reliability with modern permanent‑magnet efficiency, all wrapped in a compact, air‑cooled package. Whether you need a modest 0.65 m³/min for a small workshop or a robust 4 m³/min for a high‑throughput plant, the SLV family offers a power‑matched solution that saves energy, reduces noise, and delivers a long service life.
