Premium Energy Efficiency, Stable Performance
BLT L Low-Pressure Air Compressor Series
China is home to a large number of enterprises in industries such as textiles, ceramics, glass, and chemicals, where competition is fierce and production cost pressures are significant. In the early application of compressors in these industries, unreasonable selection and pressure matching led to enormous energy waste and increased production costs. To address low-pressure industry applications, BOLET tailored solutions for customers, implemented lean manufacturing, and developed a new generation of low-pressure screw compressors.
Atlas Copco Air End • Developed specifically for low-pressure applications, the Atlas Copco air end features an optimized SAP profile, delivering average energy savings of over 25% under low-pressure conditions. Equipped with SKF heavy-duty bearings and a high-stiffness rotor, it minimizes mechanical losses and extends bearing life by 30%. | |
Self-Developed Intelligent Control System • Designed by the Atlas Copco Group, the control system is fully imported. | |
Electrical System • Standardized design for safety and reliability. | |
Vacuum Intake Valve
| |
Premium Motor • High-efficiency design with SKF bearings throughout to ensure an extra-long service life. | |
Stable and Clean Air Supply
| |
Pre-Filter Protection • Specially designed pre-filter guard for industries like textiles, preventing lint and debris from entering the cabinet, keeping the interior clean, extending maintenance intervals, and enabling easy, reusable cleaning. | ![]() |
