Comparison between water lubricated oil-free screw air compressor and dry twin-screw compressor

Comparison of Host Compression Efficiency: 

Water-lubricated oil-free screw compressors are approximately 15% more energy-efficient than dry-running oil-free screw compressors. 

Water-lubricated oil-free screw air compressors are easy to operate and can be started at any time. 

Dry oil-free screw compressors require "drying out" each time they are started to prevent wear or seizure of the main unit. 

Ultra-low speed, nearly isothermal compression: Saman water-lubricated oil-free screw compressor operates at 2970 rpm with a main unit temperature below 60°C, while dry oil-free screw compressors run between 12,000 and 20,000 rpm with a main unit temperature reaching up to 200°C. 

Host Mechanical Analysis Comparison: 

Water-lubricated oil-free screw compressors offer better mechanical balance and longer main unit lifespan compared to dry-running oil-free screw compressors, with the main unit lasting twice as long in practical applications.
