L series permanent magnet rotary screw air compressor 3-5 bar are specially developed for industries that need low air pressure operation such as textile, cement, glass and food. With a low pressure range from 3 bar to 5 bar, the power range of L series is from 37kw to 132kw and the air delivery of that is from 8.34m3/min to 85.82m3/min.

The main engine is a low pressure design developed by MOAIR instead of an ordinary one. When a low pressure compressor is equipped with a common main engine, the air will be largely compressed first and then released, which will lead to unnecessary high energy consumption. However, a professional low pressure main engine will save 10%-20% energy compared with common compressors.

The industrial rotary screw air compressors are equipped with motors with a protection degree of IP54 and inovance frequency inverter, which turn out to be effective, energy-saving, structure-compact and lower noise.

Examples of comparison of low pressure compressor's and common compressor's working conditions in the low pressure state:
When users' actual need for pressure is 0.4MPa, however, if a 0.8MPa one was used in this case, the compressor will compress the air to 0.8MPa first and then reduce it to 0.4MPa by pressure-reducing valve or other ways. That is to say, the 0.8MPa energy consumption is taken by users.

For example, the actual air delivery of 45kw/0.4MPa low pressure compressor of MOAIR is 10.84 m3min and the actual work is 44.8KW and the specific power is 4.13kw/m3. However, the specific power of common 45kw/0.8MPa compressor is 8.1kw/m3, according to the two level energy efficiency calculation. In this case, professional 0.4MPa low pressure compressor can save nearly 49% energy compared with common ones.
