Screw Blower Specifications

 Working Principle
A rotary screw compressor using twin meshing screws for positive displacement air compression.Provides smooth, pulsation-free airflow with lower vibration/noise compared to piston blowers.
 
  
 
 

Main characteristics
 
1,The male and female rotors of oil-free screw blower are precisely designed. Compared with roots blower,it can achieve internal compression in the cavity,with higher efficiency and 20% higher energy saving performance under the same energy consumption conditions.
 
2,Stable airflow,less airflow fluctuation when pressure changes.
 
3,Applicable to higher pressure ,low noise.
 
4,Available with PLC intelligent remote control and different communication methods, convenient for operation management.
 

Applications
 
Wastewater Treatment: Variable aeration demands in biological processes.
 
Industrial Processes: Pneumatic conveying, fermentation, or manufacturing requiring stable airflow.
 
HVAC Systems: Efficient air handling in large facilities.
 

Advantages
 
Energy Efficiency: PMSM + VFD reduces energy consumption by 10% compared to fixed-speed systems.
 
Precision Control: Real-time adjustments optimize performance for varying demands (e.g., aeration in wastewater treatment).
 
Lower Maintenance: Fewer moving parts and reduced wear from soft starts and stable operation.
 
Environmental Benefits: Lower carbon footprint and potential eligibility for energy-saving incentives.
