Compare scroll compressor with general oil-free screw air compressor and piston air compressor
Oil-free scroll compressor | General oil-free screw air compressor | Oil-free piston air compressor | |
Compression Principle | The dynamic and static vortex plates intermesh to complete a continuous working process of suction, compression and exhaust. | Through the ion high-speed spinning to complete the process of suction, compression and exhaust | Piston air compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure |
Shake & Noise | Low noise, vibration acceleration is less than 1g, noise is less than 62db at 1 meter. | Air-end intermesh, 15000 rpm, high noise | Frictional contact between piston and cylinder wall, pulsed air influences the vibration noise |
Maintenance | Less number of parts, reduce replace times, less maintenance and maintenance cost. | Due to air-end running high-speed, the filters need to replace usually | High probability of machine wear lead to increase maintenance times and cost |
Structure & Weight |
The air-end only 30kg | The air-end uses second-stage compression and cooling, complicated structure |
Complicated structure |
Reliability | Structure is simple, less parts, higher reliability | The air-end includes shaft seal, cooling, transmission systems, more parts. | Probability of machine wear is high |
Energy saving Environmental Protection | Highest EER air compressor, compressed oil without oil | The EER is less than scroll compressor | The EER is less than scroll compressor |
