two stage vsd compressor with an asynchronous motor for sale

Features

• Patented air end
  

The design of ratio 5:6, meeting the standard of European energy label class 1.

• specialized compressor motor

The IE3 high efficiency compressor motor guarantees the operation round the clock and saving electricity.

• Specialized compressor inverter

Strictly comply with the standars of EMC: highly-efficicent PWM inverter controls the rotary speed of the motor according to the air demand. There is no compressed air waste.

Inverter as the soft starter helps reduce the launching current when starting machine, which is a way to protect the compressor.

 Two control system:  fixed speed(contactor) and VSD. two control system can change over freely. In the case the inverter fails, the compressor can change over the fixed speed mode to keep running. This function will do great help in those factory where no standby machine is available.

• Intelligent control system

Greenair's GAVSD series intelligent control system is able to conduct remote control through computer interface and achieve simultaneous control for multiple compressors.

• Load and Unload inlet Valve

Patented design of inlet valve,sinking gravity sensor oil stop valve,can effectively stop the oil reverse and largely reduce the inlet obstruction loss.Integration of discharge valve, air admission valve, solenoid valve and proportional valve into an intake valve makes it install easily and quickly.

• High efficient variable frequency drive

At Greenair, a highly efficient PWM variable frequency drive is used according to the EMC standards, reducing harmonic distortion and power loss to the motor.

• Variable-frequency speed control system

The GAVSD series compressor uses an patented design air end with the drive motor speed altered accurately based on compressed air demands. Under these conditions, the optimum energy efficiency and less pressure surges are achieved with the pressure surge ranging within 0.1bar, ensuring a constant voltage output.

• Motor soft starter

This motor soft starter is able to achieve a variable frequency soft start without the use of a gear box, which produces no peak current when the compressor starts up, reducing mechanical pressure and ensuring a more stable operation and longer lifespan of the air compressor.
