Core advantages

Extremely low failure rate
With only a single-stage compressor, there is no complex gearbox or secondary rotor. The oil circuit, air circuit, and control logic are all simpler, making maintenance easier. Fewer wear parts result in lower maintenance costs and greater ease of use.
High reliability
Low speed and gentle operation, suitable for 24-hour continuous work. Stable operating conditions, less prone to problems such as high temperature and overload. Low requirements for environment, power grid, and operator skill.


High cost performance
Lower price than two-stage compression and permanent magnet inverter models. Low initial investment, suitable for factories with limited budgets and stable gas supply.
