Built for Standard and Medium-Pressure Industrial Air Demand
The RUEGO JYS-HA Series is an oil-lubricated two-stage screw air compressor for industrial systems that require 8, 10 or 12.5 bar compressed air. The range combines two-stage compression with permanent magnet variable-speed control and covers 37–500 kW with air delivery from 5.2 to 100.0 m³/min, depending on model and pressure.
Typical duties include centralized factory air supply, machining and CNC workshops, automotive-component production, electronics manufacturing, general manufacturing and energy-saving replacement projects. Final selection should be based on operating pressure, required flow, load profile, voltage, cooling method, site conditions and downstream air-quality requirements.
Why Use Two-Stage Compression with VSD Control?
Pressure Options for Different Industrial Duties
The series covers 8, 10 and 12.5 bar duties so buyers can match the compressor to equipment and pipeline requirements. Air delivery changes with model and pressure, so the rated flow must be confirmed at the selected operating pressure.
Two-Stage Compression for Long Running Hours
Two-stage compression divides the compression duty between two stages to support stable, continuous industrial operation. Actual energy performance still depends on the load profile, operating pressure and complete system design.
Variable-Speed Output for Changing Demand
Permanent magnet VSD control adjusts compressor output to changing air demand, helping reduce unnecessary unloaded operation and pressure fluctuation in systems with variable consumption.
Cooling and Maintenance by Project Condition
Cooling can be air-cooled or water-cooled according to the model and project. Ventilation, cooling-water conditions, foundation capacity, electrical supply, maintenance clearance and ambient temperature should be confirmed before the final configuration is approved.
Where JYS-HA Fits, and What to Confirm
JYS-HA is intended for standard and medium-pressure industrial air systems. Confirm the pressure and air-quality requirement at the point of use before choosing the series.
Suitable Applications
- Centralized factory air stations serving multiple production lines.
- Machining, CNC, automotive-component and general-manufacturing systems with 8–12.5 bar demand.
- Long-running or variable-demand systems being evaluated for VSD replacement.
Conditions to Confirm Separately
- For confirmed 5 bar low-pressure large-flow duty, compare the JYS-HL low-pressure series.
- If the process requires oil-free air, choose an oil-free compressor; downstream treatment does not make an oil-lubricated compressor oil-free.
- Laser-cutting auxiliary air requires equipment-specific pressure and air-quality confirmation; JYS-HA is not a dedicated laser-cutting series.
A two-stage VSD compressor is not automatically the most efficient choice for every plant. The result depends on pressure, flow, operating hours, load variation, piping and downstream treatment.
Plan the Complete Industrial Compressed Air System
Compressor selection should be reviewed together with the distribution network and downstream treatment:
- Size piping for rated flow, distance, simultaneous demand and acceptable pressure drop.
- Use an air receiver when demand changes require additional buffering and pressure stability.
- Add a refrigerated air dryer for general moisture control, or confirm a desiccant dryer when a lower pressure dew point is required.
- Select precision filters and automatic drains for the required oil, particle and condensate control.
- For water-cooled models, confirm cooling-water flow, temperature, pressure, water quality and circulation conditions.
For a broader comparison of pressure ranges and two-stage configurations, review the two-stage screw air compressor series before confirming the final project specification.
