Explore Our Rotary Screw Air Compressor Types
Permanent Magnet VSD Screw Air Compressors
Variable speed drive screw air compressors automatically match air output to real-time demand, saving up to 35% energy in fluctuating production loads. VFD screw air compressor working principle and full series details.
Two-Stage High-Efficiency Screw Compressors
Two-stage compression reduces the compression ratio per stage, improving specific power and lowering operating temperature for heavy-duty continuous operation. Two-stage rotary screw compressor manufacturer options.
Oil-Free Rotary Screw Air Compressors
Class 0 oil-free screw compressors are designed for food, pharmaceutical, electronics, and other contamination-sensitive processes. Oil-free rotary screw air compressor models available.
Integrated Screw Compressor with Air Dryer & Tank
All-in-one screw compressor packages combine compressor, refrigerant dryer, air receiver, and filtration in a compact skid for fast installation.

Frequently Asked Questions (FAQ)
What is the lifespan of a rotary screw air compressor?
With proper maintenance, a quality rotary screw air compressor airend typically lasts 40,000–80,000 running hours depending on operating conditions and service intervals.
How to select the right kW capacity for my factory?
Calculate total air demand, duty cycle, and maximum working pressure. As a rule, choose capacity at least 20–30% above average demand to allow for leaks and future expansion. Panrui engineers can size your system based on a complete air audit.
