📌 Lubricated Rotary Screw Air Compressors (22 – 30 kW)
Lubricated rotary screw compressors in the 22 – 30 kW class are medium-power industrial units designed to deliver continuous, smooth compressed air for manufacturing, workshop, production lines, and other industrial uses. These compressors use oil in the compression chamber to lubricate, seal, and cool the screw elements, improving efficiency and life span.
📊 Typical Performance Range
📌 Power: ~22 kW (30 HP) up to ~30 kW (~40 HP)
📌 Airflow: ~0.92 m³/min to ~5.5 m³/min (depending on model and pressure)
📌 Pressure Range: Typically 5 – 13 bar (user selectable via controller)
📌 Drive Options: Fixed-speed and regulated/variable-speed versions available
⚙️ Key Benefits
✔ Continuous operation: No duty cycle — can run 24/7 for demanding industrial use.
✔ Smooth, pulsation-free airflow: Ideal for pneumatic tools, spray booths, automation, and plant air.
✔ Energy efficiency: Modern designs optimize airend performance and motor efficiency.
✔ Low oil carryover: High performance separators ensure clean air with minimal oil content (< 3 ppm).
✔ Flexible configurations: You can choose base units, tank-mounted or integrated systems with dryers and filters.
🛠️ Applications
These compressors fit a wide variety of industrial environments, such as:
Metal fabrication and machining
Automotive shops and assembly lines
Plastic and injection molding plants
Food production and packaging
Pneumatic tools and air-driven equipment
They are particularly suitable where you need steady airflow at moderate pressure without frequent stops.
🧠 Tips Before Buying
✅ Decide whether you need fixed-speed or variable-speed drive (VSD) — VSD can save significant energy if your compressed-air demand varies over time.
✅ Include air treatment (dryers & filters) if you are using air for sensitive tools, painting, or food-grade applications.
✅ Confirm output pressure and flow requirements for all tools and machinery you plan to run simultaneously.
