Rotary Screw Air Compressors
Single and Two-Stage Lubricated Screw Compressors 160 - 250 kW
Fixed & Regulated Speed L160 to L250
By listening to our customer’s needs and wishes, and incorporating the latest technology and design concepts, CompAir has delivered an impressive range of compressors featuring higher free air delivery, new compact footprint, lower noise levels, new split radial cooling fan design, new controller, and many more features besides.
New CompAir FourCore range balances two-stage efficiency with single-stage footprin
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 Classic 160 to 250kW Range
The new E models are offered in addition to the well established existing large screw compressor range which has been offered over many years, with 1000's of installations worldwide, continuing to power the larger volume air requirements of a diverse range of industries.
How Industry benefits from CompAir:
Premium airend providing high reliability
Automatic motor lubrication system for optimum protection
Low installation costs thanks to the compact design
High quality air
Safe and economical operation
Excellent accessibility contributing to the low maintenance costs
Rotary Screw Air Compressors – Single & Two-Stage Lubricated (160–250 kW) are large industrial compressors used for continuous compressed-air supply in factories, power plants, steel plants, cement plants, and large manufacturing facilities. Models in the L160–L250 range typically provide high airflow with efficient energy use.
1. Overview of L160–L250 Screw Compressors
Type: Oil-lubricated rotary screw compressor
Power range: 160 – 250 kW motor
Air delivery: approx. 6 – 47 m³/min
Pressure range: 5 – 13 bar
Cooling: Air-cooled or water-cooled options
Operation: Continuous industrial duty
These compressors use two intermeshing helical screws to compress air while oil is injected to lubricate, seal, and cool the airend.
2. Fixed Speed vs Regulated Speed
Fixed Speed
Motor runs at constant RPM.
Compressor either fully loaded or unloaded.
Best for stable air demand.
Regulated Speed (RS / Variable Speed)
Uses variable speed drive (VSD).
Motor speed changes according to air demand.
Energy savings up to ~20–35% in fluctuating demand systems.
3. Typical Models in the Range
Model Motor Power Air Flow (approx.) Typical Use
L160 160 kW ~21–28 m³/min Medium-large plants
L200 200 kW ~27–36 m³/min High-capacity production lines
L250 250 kW ~33–42 m³/min Heavy industrial operations
At 7.5 bar pressure, an L160 unit can deliver about 28 m³/min, while an L250 can exceed 42 m³/min depending on configuration.
4. Key Features
High-efficiency airend for maximum air output
Oil-injected screw design for durability
Low noise enclosure
Compact footprint
Electronic controller for monitoring
Split radial cooling fan for improved cooling
Automatic lubrication system
5. Typical Industrial Applications
Automotive manufacturing
Steel and metal processing
Cement plants
Power plants
Food & beverage factories
Chemical plants
Textile mills
💡 Simple explanation:
A 160–250 kW rotary screw compressor is a large industrial machine that continuously produces compressed air for heavy production systems, and the regulated speed version saves energy when air demand changes.
