The CompAir L23–L29 RS range are lubricated rotary screw compressors designed for industrial compressed air applications in the 22 – 30 kW power class. These are available in both fixed-speed and regulated-speed (RS / variable speed) models for optimized performance and energy use.
🛠️ Key Features & Benefits
✔️ Superior Energy Efficiency
Built with an in-house high-output airend operating at slower speeds to reduce energy consumption.
Regulated Speed (RS) models adapt output to actual air demand, cutting idle energy waste.
✔️ High Reliability & Low Maintenance
Integrated oil filter, oil regulation valve, and fail-safe shaft seal reduce external hoses and potential failure points.
Designed for trouble-free operation with premium quality components and ease of service.
✔️ Small Footprint & Flexible Installation
Compact footprint suitable for workshop and plant installations where space is limited.
Available with integrated peripherals such as refrigerant dryers and heat recovery options.
✔️ Advanced Monitoring & Industry 4.0
Supports modern controls and, in some markets, iConn Industry 4.0 connectivity for remote monitoring and analytics.
