More than 70% of a compressor's costs of ownership are related to energy consumption. By choosing compressors with permanent magnet technology iPM, you can save up to 45% on energy costs compared to traditional fixed-speed compressors. Depending on your operation and circumstances, your initial investment could pay off faster than you expect, contact us to find out.

4 Bar Permanent Magnet Rotary Screw Air Compressor

Description

The 4 bar permanent magnet rotary screw air compressor features an discharge pressure of 4 bar with a power range from 37kw to 132kw and air delivery range of that is from 9.82m3/min to 35.61m3/min.

The compressor is specially developed for industries with low air pressure requirements such as textile production, cement processing, and food handling. The equipment offers effective operation, energy savings, compact structure, and minimal noise.

Motor
  • The industrial rotary screw air compressor uses a motor with a protection degree of IP54, offering added stability.
  • The PM motor and male rotor are directly connected on one shaft, without transmission efficiency loss as it does not require a gearbox and belt.
  • The PM motor offers excellent performance and maintains a high degree of efficiency at low frequency and low velocity for higher energy efficiency.
  • With the design combination of high performing permanent magnet and special rotor structure, our PM motor's efficiency is 30% better compared to similarly sized induction motors.
  • Equipped with indepandent air-cooled cooling system, the motor doesn't need to work with compressor cooling system.
  • The stator of the motor uses a corona-resistant enameled wire which is specially designed for frequency converters, and features excellent insulating properties and a long service life.

Inovance frequency inverter
  • The inovance frequency inverter has an optimized structure and outstanding after-sales service network around the world.
  • The inovance frequency inverter is easy to use and has high reliability.
  • The inovance frequency inverter has a built in circuit breaker. It will stop at once and give an alarm the moment any abnormality occurs while the air compressor is running.
  • The inovance frequency inverter has high precision under the circumstance of steady speed operation.
  • The inovance frequency inverter has a high-speed output under the control of vectors.
  • There is a built-in DC reactor to avoid damage of the inovance frequency inverter due to unstable voltage.

Features

  • The main engine is a low pressure design developed by MOAIR instead of an ordinary one.
  • The industrial rotary screw air compressor is equipped with a permanent magnetic-synchro screw airend created by MOAIR independently, which can save 15% energy compared with common asynchronous frequency conversion screw compressors and 30% energy compared with common screw compressors.
  • With soft starting method, the instant values of electric current when the motor starts is largely declined, which can protect the motor and other parts of air compressor.
  • The structure of the whole machine is designed to be more compact, saving significant floor space. Also, the volume of the permanent magnet synchronous motor is half the size of common motors.
  • The combination of Teflon hose and steel pipe reduces vibration and noise effectively.
  • It has an intelligent display for easy operation.
  • The whole series are equipped with motors of IP54, which offer a high protection degree.
  • Our products are CE certified.

Energy-saving

  • With a permanent magnet motor, the industrial rotary screw air compressor is effective and energy-saving.
  • With specially developed vector-controlled frequency inverter, it has a low loss rate.
  • The factors above lead to much lower energy consumption whether it is in a full load state or a light load one.
