Rotary Screw Air Compressors
L Series 7 - 11 kW
Fixed & Regulated Speed
Well known in the industry for quality and reliability, CompAir continuously develops and expands the L-Series to achieve optimum performance and efficiency and maximum flexibility. The wide range of screw compressors from 7 to 11 kW includes fixed and regulated speed models, high efficiency models and is available as airstation including receiver and refrigerant dryer.
Engineering Excellence
Compressors are more than just a financial investment, they are a key component in ensuring that manufacturers, processors and operators receive consistent, high quality low cost air. The screw compression element is the heart of the compressor and therefore CompAir keeps the design and manufacture in-house, using the latest CNC rotor grinding machinery, coupled with online laser technology. The resulting reliability and performance ensure that operating costs will remain low throughout the compressor’s life.
Benefits
Compressor base mounted
Complete package including compressor, dryer and receiver
Small carbon foot print (by mounting the components on the receiver the footprint is reduced up to 55%)
In-house AirEnd
Highly efficient motors
Easy maintenance
Wide regulation range
📌 What “L Series 7–11 kW” Usually Means
According to industrial manufacturer specs (e.g., from CompAir L-Series documentation):
Power range: ~7.5 kW up to 11 kW (≈10–15 HP).
Types: Available in fixed-speed and regulated-speed (RS) versions (variable speed).
Design: Lubricated rotary screw airend with in-house engineered rotors for reliability.
Applications: Workshops, factories, pneumatic tools, painting, sandblasting, and general industrial air systems.
Optional configurations: Can include an air receiver tank and refrigerant dryer to form an air station package.
These compressors deliver continuous airflow at working pressures often around 7–10 bar (≈100–145 psi) depending on model and setup.
🛠️ What to Consider When Choosing
✅ Duty cycle: Rotary screw compressors are designed for continuous operation vs piston compressors.
✅ Energy savings: Variable-speed (regulated) units adjust delivery to demand, reducing power use.
✅ Noise & footprint: Many L-Series are designed to be compact and quieter than older designs.
✅ Air quality: If you need oil-free output (e.g., for food or pharma), you may need additional filtration or a different compressor type (oil-free rotary screws).
