📌 CompAir L23 – L29, RS | Lubricated Rotary Screw Air Compressors (22–30 kW)
📦 Product Description
The CompAir L23 – L29, RS series are industrial-grade lubricated rotary screw air compressors designed for 22 kW up to 30 kW motor power. These units are engineered for high reliability, energy efficiency and continuous operation in demanding compressed air applications.
🔧 Key Features & Benefits
Performance & Efficiency
Available in both fixed speed and regulated/variable speed (RS) versions, offering better energy efficiency and adaptability to varying air demands.
Energy-efficient, high-output compressor element designed for slow rotational speed—cuts energy costs.
Premium quality compressed air with low oil carryover (< 3 ppm) thanks to advanced separator systems (in many configurations).
Integrated oil filter and oil regulation valve with minimal external hoses for improved reliability.
Advanced Controls & Monitoring
Equipped with Delcos Pro controller (or equivalent) for easy monitoring, adjustable pressure and protection of the unit.
Some RS models include remote monitoring capability (e.g., iConn Industry 4.0).
Design & Serviceability
Small footprint and compact design.
Low maintenance needs and reduced servicing costs.
Options for integrated refrigerant dryers, heat recovery systems, condensate solutions, filters, and other compressed air accessories.
📊 Typical Technical Data (Indicative)
Model Motor Power Flow Range Pressure Range Noise Approx. Weight
L23 / L23RS 22 kW ~0.92–~4.1 m³/min ~5–13 bar ~67–68 dB(A) ~650–680 kg
L26 / L26RS 26 kW ~1.0–~4.8 m³/min ~5–13 bar ~68–69 dB(A) ~680–710 kg
L29 / L29RS 30 kW ~1.0–~5.5 m³/min ~5–13 bar ~69 dB(A) ~680–712 kg
Ranges depend on pressure setting and RS vs fixed-speed versions.
