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.
Component characteristics
1,Screw Host
Efficient profile rotor design.
Adopting national standard level 5 precision synchronous gears and driving gears.
Innovative bearing arrangement, using fixed radial and axial bearings, increases service life.
Piston ring seal+magnetic seal to achieve oil and gas separation between compression chamber and lubrication chamber.
2,Permanent Magnet Motor
Magnetic field properties, can maintain its magnetic field without external energy.
High efficiency and energy-saving, with an average efficiency of 75% to 80% within the speed range of 1000-3600r/min.
High voltage stabilization accuracy can extend the service life of the battery.
No electric brushes, no collector rings, and no electric sparks generated during operation, so there is no wireless interference, greatly improving performance.
3,Operating control system
Integrated workstation monitoring instruments, signal control modules, frequency converters, touch screens, etc., no additional installation required.
Optimize the selection of driving components, parameter settings can accurately achieve high efficiency.
Fully equipped with automatic control and protection functions, while achieving online and remote control.
Specifications to Consider
1,Airflow capacity (m³/min or CFM)
2,Pressure range (bar or psi)
3,Motor power rating (kW) and efficiency class (e.g., IE5)
4,Noise levels (dB) and cooling method (air/water-cooled).
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.
