What Is a Screw Air Compressor?

A screw air compressor is a type of compressor that uses two rotating helical screws (rotors) to compress air. Unlike piston compressors, which work in cycles, screw compressors provide continuous and smooth airflow, making them ideal for industrial applications.

Main Features:

• Continuous operation (24/7 running capability)
• Low noise and vibration
• High energy efficiency
• Long service life
• Stable air pressure output

• Most common type
• Used in general industry
• Lower cost

2. Oil-Free Screw Compressor

• Used in food, medical, and electronics industries
• Provides clean, contamination-free air
• Higher price

3. Portable Screw Compressor

• Used for construction and outdoor work
• Easy to move

4. Fixed Industrial Screw Compressor

• Installed in factories
• High capacity and efficiency
