Ultra Silent Generator
The noise level of silent gensets can be reduced by 15-35dB(A)through multiple noise control devices, which ensure quiet operations, thus having no effect on daily activities. The silent genset is capable of working in residential areas, offices and other environments during night time which are sensitive to noise.
