Rotary Screw Air Compressors
L45+ to L132RS
CompAir lubricated rotary screw compressors incorporate the very latest technological advances and guarantee a continuous supply of high quality compressed air.
New CompAir FourCore range balances two-stage efficiency with single-stage footprint
CompAir has announced the launch of its new 110 to 250 kW FourCore compressor range, combining best-in-class compressed air efficiency with a small footprint and sustainable design for eco-conscious businesses.
The FourCore range offers all the capabilities of a two-stage compressor, but with only the footprint of a single-stage unit. It therefore provides businesses – who might not have previously had the on-site space available – the opportunity to take advantage of the capabilities of two-stage technology. And when compared with previous single-stage compressors in this size range from CompAir, the new models are up to 8 per cent more efficient, offering a best-in-class oil-lubricated solution for decision makers.
Our application engineering team, based at the Simmern Centre of Excellence production site in Germany has designed and engineered a brand new, patented technology that offers best-in-class energy efficiency. They have developed a premium efficiency 2-stage model for fixed and regulated speed compressors using the new technology of the compact double stage airend. What’s unique about this design is that the airend has 1 motor and 4 rotors located in a single, semi-integrated casting. This differs from traditional 2-stage compressors, providing a compact package with high energy savings. In fact, these machines are the same size as a 1 stage machine due to new airend technology.

The L45+ to L132RS series refers to industrial oil-lubricated rotary screw air compressors from CompAir’s L-Series, typically used for medium to heavy-duty applications.
🔧 Overview: L45+ to L132RS Range
Power range: ~45 kW to 132 kW
Type: Rotary screw (oil-injected)
Variants:
Fixed speed (L45+, L55+, etc.)
Regulated Speed / VSD (RS models like L75RS, L132RS)
Designed for continuous industrial operation (24/7)
⚙️ Key Features
From the L-Series design:
High efficiency airend (FourCore technology)
Wide regulation range (especially in RS/VSD models)
Integrated air treatment options (filters, dryers, separators)
Heat recovery options for energy saving
Robust cooling system (large aftercooler + fan)
🚀 Performance Advantages
Compared to traditional piston compressors:
✔ Continuous 100% duty cycle operation
✔ Higher air output with smooth flow (no pulsation)
✔ Lower energy consumption, especially with VSD models
✔ Lower maintenance & longer lifespan
🔄 RS (Regulated Speed / VSD) Benefits
The RS models (e.g., L132RS) automatically adjust motor speed based on air demand:
Saves significant energy (up to ~60%)
Reduces load/unload cycling
Ideal for variable demand applications
🏭 Typical Applications
These compressors are used in:
Manufacturing plants
Automotive & paint shops
Food & beverage processing
Pharmaceuticals (with proper filtration)
Heavy engineering & construction
