• Ultrahigh intrinsic coercive rare earth permanent magnetic material with strong anti demagnetizing capacity
• Possible constant torque output within scope of locked rotator and rated rotating speed
• Special asymmetrical magnetic circuit design, making low-rotating-speed torque ripple small
• High balancing precision, stable and high-speed operation, low noise and small vibration
• Full-sealed or high protection-grade appearance structural design

Infinite volume control air inlet system

The compressor adopts infinite volume control air inlet system. It could operate without magnetic valve. Built-in function of the check valve can reduce malfunctions. The compressor is free from unloading process and shows higher energy efficiency. This compressor can operate at frequencies from 0-300HZ and realize high energy efficiency in real sense.

Industrial manager function

Wan Beardsley air compressor system can pre-set weekly work schedule according to your working hours in the factory, air compressor will punctually and automatically power on ana off accordinq to preset working schedule

Variable-frequency control range is broader with more energy conservation

It has advantages of low rotating speed high output torque, variable-freciuency control mode is broader than ordinary inductive variable-frequency motor, especially its 30%-80% air consumption in low-loaa working area saves by 15%-38% when compared with that of power-frequency compressor, and by 10% when compared with ordinary variable-frequency compressor. The lower load ratio, the more obvious the enerqv-savinq effect.

Leading constant pressure control

AVF permanent magnet variable frequency screw compressors can sustain the air supply at the pressure of 0.1 bar in any loading conditions. In case of larger demands for air supply, the compressor can increase its rotation speed without changing the pressure to guarantee the air volume. In case of lower demands for air supply, the compressor can reduce its rotation speed without changing the pressure to meet such demands. In case of no demands for air supply, the compressor will switch to sleep mode to save energy. When actual pressure achieves the wakening standard, the compressor will immediately start up with rapid response of frequency converters even in sleep mode.

Reduce energy costs

• When the energy accounts for above 70% of the life cycle cost (LCC) of compressor, the energy consumption optimization becomes essential. In fact, the power consumption for the production of compressed air accounts for over 40% of the total power consumption of the plant, so the energy consumption optimization can even determine its success. Using the permanent-magnetism frequency-conversion technology of Dresdnerlan, we can provide partners for your cost saving. WZS series of products can truly reflect the demand for compressed air, making substantial energy saving become a reality
• Traditional compressors are operated between two set pressure points using the control methods of "full load and no load". The compressor turns into no load mode when the pressure reaches the maximum. When the air demand is medium or low, the no-load power will be consumed excessively, which will result in large amount of waste.
• Because no unnecessary power consumption will be generated, the energy cost reduced by the permanent-magnetism frequency-conversion can be up to 35% or more. The life cycle cost (LCC) of the compressor can be reduced by an average of 22%. In a word, compared with the compressor with invariable rotate speed, Wan Beardsley compressor can recover the extra cost within 1 or 2 years.

Steady Pressure

It tracks system gas volume changes automatically, and adjusts the revolving speed of compressor accurately with the use of PID (proportional, differential, integral), to keep the system pressure stable.

Start without stamping

• The variable frequency starting method reduces the impact of the start of the compressor on the power grid and mechanical parts greatly, thus extending the life of the machine.
• Eliminate invalid transitional period from full-load power to no-load power
• Avoid excessive no-load power consumption
• Maintain the net pressure section
• Reduce the overall average operating pressure
