This project is a containerized project for the diesel generator set. An intake filter silencer is installed on the roof. The filter is a plate filter, which intakes air from three directions through the intake box and has high waterproof performance and a filtering accuracy of 5um. The silencer section is a flat dissipative silencer with noise reduction capacity of more than 25dB (A) and an intake resistance of less than 400Pa. The whole device is detachable, is connected to the container by bolts and is structurally waterproof.
