Integrated Rotary Screw Compressor, HNS/A Series

In many of today's industries, rotary screw air compressors are used to provide outstanding performance and ensure stable operation. Rotary screw compressors that are oil-lubricated to keep the production process running smoothly, offering reliable and energy-efficient air solution. Our oil-lubricated rotary screw compressors are available in a range from 7.5kW to 15kW.

Free air delivery: 0.8-2.5 m³/min Discharge pressure: 0.8 - 1.2 Mpa Power: 10-20HP (7.5-15KW) Rotational speed: 0-3000 rpm
 Minimized energy cost with direct drive

 Highest reliability and lowest noise level

 Smart microcomputer control system
Premium branded motors

Main motors are specially designed for air compressors and they are designed with class F insulation and class B temperature rise to prolong the motor’s lifespan. SKF branded bearings are configured to ensure energy efficiency.

Screw Air End

Our screw air compressors feature reliable screw rotors, triple shaft seals, fewer consumable parts, compact design, enhanced air discharge volume and more stable performance.

Cooling system

High-pressure cooling system brings high dissipation efficiency which allows the rotary screw compressors to perform continuously in high-temperature or high-humidity environments while maintaining optimal working efficiency.

Efficient filtration system

The oil filter can remove the contaminants form the lubrication oil and ensure the operational reliability.

Microcomputer system

It improves the safety of air compressors by providing functions like open-phase protection, phase sequence protection, tempeatrue protection and air volume adjustment.

Smart electric control system

Electric control system adopts LCD human-machine interface for users to easily get operation information including temperature, pressure, running time, auto fault diagnosis. Controlled by microcomputer, our electric control system provides protection functions and auto alarms, including open-phase, overload, motor unbalance, high voltage, low voltage, high discharge temperature (>110℃), high discharge pressure protection, etc. The air compressor also has an emergency-stop button to ensure the operational safety.

Smart IoT management system

Smart IoT management system realizes 24/7 automatic monitoring and automatic failure alarm in more efficient and user-friendly way.
