The silencer kit for the Honda EU20i is designed to soundproof the alternator even more. The hood is made of adonized aluminium sheets, Its foldable and lined with highly soundproof material. It is delivered together with the exhaust pipe already mounted on the generator and a silencer pipe (1 meter long) which has to be connected to the exhaust pipe once on the location and with the generator inside the hood.
With this kit we can reduce the noise of this generator by approximately 17dB what leaves the sound to approximately 72dB (measuring the noise level one meter away).
