In order to stabilize the speed and air pressure while lowering energy costs, HANOS offers PMSM rotary screw air compressors that employ advanced synchronous vector control technology to adjust the motor's rotating speed in accordance with air consumption. We provide 7.5kW to 132kW rotary screw air compressors that are offered with PMSM.

• Free Air Delivery: 0.8-20.26m³/min
• Discharge Pressure: 0.8 - 1.2 Mpa
• Power: 10–175 hp (7.5–132 kW)
• Rotational speed: 0-3000 rpm

Rotary screw air compressor with PMSM HNS series adopt advanced synchronous vector control technology to adjust the motor's rotational speed according to the air consumption, so as to stabilize the speed and air pressure and minimize energy costs and overall compressor life cycle costs.

• Efficient Permanent Magnet Synchronous Motor

  Higher power factor and lower power loss to offer 5~8% higher power efficiency.
  Wide range of compatible frequency (0Hz-200Hz).
  Constant motor efficiency at different loadings.
  High torque design allowing for starting with load.
  Increase to the rated rotational speed immediately.
  3dB lower noise than asynchronous screw air compressors.

• Soft starting design

  Variable frequency soft starting greatly reduces impacts that the air compressor causes on electric system and mechanical parts and prevents damaging the electric equipment.

• 

  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 air compressors to perform continuously in high-temperature or high-humidity environments while maintaining optimal working efficiency.

• 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.
