GASFlow presents the LS Series fixed speed screw air compressor, a robust lineup engineered to meet industrial compressed air solutions. With power ratings spanning 4 to 355 kW and pressure options at 7.5, 8.5, 10.5, and 13 bar, the LS Series delivers reliable performance across applications through high-pressure fixed-speed compressors.

 

Features and Design

The LS Series fixed speed screw air compressor integrates proven rotary screw technology with precision engineering to create a compact, serviceable package. The machines use advanced screw element profiles that maximize volumetric efficiency and minimize internal leakage, which directly contributes to lower energy-efficient compressors operation.

 

Cooling and Filtration

Effective thermal management is essential for stable compressor operation. The LS Series features high-efficiency cooling circuits and optimized airflow paths to maintain consistent temperatures, enhancing lubricating oil life and component reliability. Integrated air filtration and separation systems protect the rotary screw elements and downstream equipment, ensuring that compressed air meets quality requirements as reliable ISO-certified rotary systems.

 

Applications 

The LS Series suits a wide variety of industrial environments. These ISO-certified rotary screw systems are appropriate for manufacturing plants, automotive assembly lines, food and beverage processing and heavy industry. High-pressure fixed-speed compressors in the LS Series provide necessary pressure for pneumatic tools, process control systems, and other high-demand applications requiring steady, reliable air supply as complete industrial compressed air solutions.

 

Safety and Compliance

Safety is integrated into every aspect of LS Series design. Protective enclosures, pressure relief systems, and fail-safe controls comply with international standards. Environmental compliance is also a priority; the energy-efficient screw compressors in the LS Series reduce greenhouse gas through lower power consumption while meeting regulatory requirements for noise and emissions.

 

Total Cost of Ownership

When evaluating compressors, total cost of ownership is a key decision factor. The LS Series fixed speed screw air compressor targets long-term savings through high energy efficiency and durable components. Energy-efficient screw compressors deliver measurable reductions in electrical consumption, while ISO-certified rotary screw systems reduce unplanned downtime and repair costs using advanced high-pressure fixed-speed compressors within robust industrial compressed air solutions.

Product Features

Premium Air-end

Newly designed Atlas Copco air-end delivers higher airflow and improved energy efficiency for stable, high-performance operation.

Intelligent Control System (45–355 kW)

Atlas Copco-developed controller with touchscreen interface and cloud connectivity, enabling real-time monitoring, easy operation, and optimized system management.

Reliable Electrical System

High-quality Siemens and Schneider components combined with an optimized wiring layout ensure long-term safety, stability, and reliable performance.

Advanced Filtration System

Pre-filter design reduces the load on the main air filter, extending service life. High-efficiency air, oil, and separator filters protect key components and ensure long-term system reliability.

Applications

With optional 2-in-1 and 4-in-1 integrated configurations, as well as two-stage compression models, the system can be flexibly adapted to different installation conditions and higher efficiency requirements, making it suitable for a wide range of industrial applications.

Designed for stable and continuous air demand, this compressor is ideal for medium to large-scale manufacturing environments. It performs best in applications with long operating hours and relatively stable load profiles, where reliability, consistent airflow, and low downtime are critical to maintaining production efficiency.
