KIPOR launched a totally new series of generators named ULTRA SILENT GENERATORS. They are applicable to construction sites, the workplace, or for emergency standby operations. The ultra silent generator sets not only provide the features of the super silent generators but greatly reduced the running noise. The running noise of KIPOR Ultra Silent generator sets is an unprecedented 53dB@7m. This great improvement is due to the unique design features employed by KIPOR engineers. KIPOR applies a electronic cooling fan instead of the engine driven fan improving the cooling performance and lowering noise. The unique air handling system reduces the bulk of the engine noise. A double muffler and the use of high quality acoustic absorbing material result in maximum silencing.
