Linghein LST Series Dual-drive Fixed Speed Screw Air Compressor
How do you get the running-cost benefit of matched air output on a fixed-speed machine? Dual drive with staged loading — two drive systems sharing the work, with no inverter to buy, maintain or lose efficiency to
Product Positioning
Linghein LST Series is a dual drive, fixed-speed (mains-frequency) industrial screw air compressor built for continuous duty
Two independent drive systems run in parallel; capacity is matched to plant air demand through staged loading, not through variable-speed control
Target users: manufacturing plants, automotive assembly lines, heavy industry and energy facilities that need stable air supply with controlled running cost
Dual Drive Architecture
Two independent drive systems (dual drive) share the load, and the unit loads / unloads in stages to follow site air demand
Intelligent load balancing keeps both drive trains inside their efficient working range and evens out running hours between them
Reliable pressure-band control holds discharge pressure stable and prevents over-pressurising the system
Because capacity is stepped inside the machine, the unit spends less time idling at low demand — the main source of energy waste on fixed-speed compressors
Energy Efficiency
Staged dual-drive loading cuts unload / idle time, which is the largest energy loss on a fixed-speed machine
Load balancing keeps each drive train close to its best-efficiency operating point during partial-load conditions
Lower power consumption than conventional single-drive fixed-speed compressors, with no frequency converter to maintain
Reliability & Low Maintenance
Two drive trains share the running hours, extending service intervals compared with a single-drive unit doing the same work
Even load distribution reduces wear concentrated on one drive train
Industrial-grade, continuous-duty design for round-the-clock operation with minimal maintenance
Straightforward mechanical structure — no inverter, no speed-control electronics to service
Applications
Compressed air supply for manufacturing plants and automotive assembly lines
Heavy industry and energy-sector facilities requiring stable, round-the-clock air
Delivers stable air supply + lower electricity cost per m³ of air, supporting corporate energy-saving and carbon-reduction targets without sacrificing productivity

Innovation and Technical Advantages
GASFlow’s double drive fixed speed screw air compressor incorporates several technical innovations aimed at improving efficiency, reliability, and total cost of ownership for industrial compressed air users
1. Double Drive Screw Element Architecture
The core innovation is the double drive screw design. By employing a twin-bearing, double drive arrangement, the compressor reduces axial load on bearings and distributes torque more evenly. This results in enhanced mechanical lifespan, lower vibration, and fewer unscheduled maintenance events
2. Energy-Efficient Performance
Energy efficiency is a critical advantage of the GASFlow unit. The energy-efficient compressors package is engineered to minimize parasitic losses and employ aerodynamic rotor profiles that optimize volumetric efficiency across the operating range
3. Pressure Versatility and Process Matching
With selectable pressure ratings of 7.5, 8.5, and 10.5 bar, the compressor can be tailored to process-specific needs. This adaptability means the same base platform serves diverse industrial compressed air applications, from moderate-pressure pneumatic systems to higher-pressure requirements in specialized processes
4. Robust Thermal Management and Filtration
Efficient heat rejection and contamination control are essential for long-term reliability. GASFlow energy-efficient compressors equips the double drive fixed speed screw air compressor with advanced cooling pathways and high-efficiency inlet filtration to prevent particulate and aerosol ingress
