The APM(S) oil-cooled series is newly launched. Its energy efficiency surpasses the national first-level standard. The oil-cooled permanent magnet variable frequency motor further reduces energy consumption by 7% compared to the APM permanent magnet variable frequency models, achieving significant energy savings, greatly lowering the total lifecycle cost of the compressor, and improving production efficiency. The APM-2S series integrates Inovance permanent magnet variable frequency technology, automatically adjusting the motor speed to match the supply of compressed air with demand, precisely controlling pressure, avoiding unnecessary fluctuations, saving energy, and reducing operating costs.
