Two-Stage Rotary Screw Compressor Manufacturer | Panrui

Panrui two-stage rotary screw air compressors use dual compression stages to reduce pressure loss and increase specific power. They are engineered for heavy-duty continuous industrial operation where stable pressure and low energy consumption are critical.

Why Two-Stage Compression Is More Efficient

Air is compressed in two sequential stages with intercooling, reducing the compression ratio in each stage and improving volumetric efficiency.

Performance Features

• Lower specific power than single-stage units.
• Reduced internal leakage and lower discharge temperature.
• Heavy-duty airend design for 24/7 operation.
• Available from 55kW to 315kW.

Recommended Applications

Mining, cement, chemical, large-scale manufacturing, and central compressed air stations benefit from two-stage high-efficiency screw compressors.

FAQ

What is the benefit of a two-stage screw air compressor?

It typically delivers more air per kW at the same pressure compared with a single-stage unit, reducing long-term energy cost.
