🔩 Technology & Type
These are rotary screw air compressors — industrial machines that compress air continuously using two interlocking helical rotors (screws). They’re oil-lubricated, meaning oil cools and seals the compression chamber for efficiency and durability.
The series (often referenced as L160–L250 or L160RS–L250RS) covers compressor power from 160 kW up to 250 kW motor ratings (approx. 215 – 335 HP).
⚙️ Single-Stage vs Two-Stage
Single-stage compressors compress air in one step — simpler and robust.
Two-stage models (especially in the newer FourCore ranges) compress air in two steps for improved efficiency and lower energy use in high-pressure or heavy-duty applications.
🔄 Fixed & Regulated (Variable) Speed Options
Fixed speed models run constantly at full speed — reliable and simple.
Regulated speed (RS, VSD) models adjust motor speed to match air demand, saving energy and reducing running costs by avoiding unnecessary full-speed operation.
📈 Key Features & Benefits
⚙️ Design & Performance
High reliability: Designed for industrial continuous operation.
Efficient air delivery: Capable of delivering large volumes of compressed air (typically ~23 – 47 m³/min depending on pressure and model) while optimizing energy use.
Two-stage advantage: More efficient than traditional single-stage designs at higher discharge pressures, with a compact footprint on the shop floor.
💡 Energy & Cost Savings
Regulated speed units help save up to ~35 % in energy costs by adapting output to demand.
The design improves motor and compressor efficiency for lower operating costs over time.
🛠️ Maintainability & Usability
Automatic lubrication systems protect bearings and reduce maintenance.
Compact footprint and improved cooling designs reduce installation space and enable easier service access.
Many models come with intelligent controllers for monitoring, trouble-shooting and optimizing performance.
⚙️ Typical Applications
These large industrial compressors are used where constant high-volume compressed air is needed, such as:
Manufacturing and processing plants
Automotive paint booths and assembly lines
Heavy machinery operation
Pneumatic tool systems
Food & beverage, textiles, and chemical industries
🧠 Summary
In short, this L160–L250 fixed and regulated speed lubricated rotary screw compressor range stands out for:
Industrial-grade performance
High reliability and continuous duty
Energy savings with regulated speed models
Lower maintenance and operating costs
