1, the remarkable low-noise performance, 75dB noise limit (a) (from unit 1M).

2, low noise diesel generating sets overall compact design, small size, novel appearance.

3, multi-layer shielding impedance mismatch acoustic enclosure.

4, road noise reduction-more efficient intake and exhaust, exhaust ducts, ensure adequate performance.

5, large impedance compound muffler.

6, bulk fuel.

7, ad hoc quick open cover, easy maintenance.
