1.Piston Air Compressor
Low cost,easy maintenance, suitable for small air demand and harsh outdoor environments.
High noise and heavy maintenance, so gradually replaced by srcew compressors.

2.Single-Screw vs. Twin-Screw Compressors
Both are stable for long-term operation.
·Twin-screw:Matyre technology, high efficiency,but expensive and hard to repair on-site.
·Single-screw:Lower machining requirements, easier local production,but efficiency drops with star-wheel wear.Suitable for airflow under 60m³/min.

3.Centrifugal Compressor
Best for large air volume above 60 m³/min with stable demand.
High efficiency,oil-free air, fewer wearing parts.
But high noise,limited adjustment range, and risk of surge.
Widely used in food and pharmaceutical industries requiring clean air.
