Abstract
A genset includes a generator, an enclosure, and a plurality of louvers. The enclosure defines a space that is at least partially enclosed, with the generator in the space. The louvers extend from the enclosure inward to the enclosed space. Each of the louvers include a short leg and a long leg, the long leg coupled with the short leg at an angle to the short leg.

A genset comprising:
- a generator;
- an enclosure defining a space that is at least partially enclosed, the generator in the space;
- and
- a plurality of louvers extending from the enclosure into the space, each louver of the plurality of louvers comprising:
- a short leg;
- and
- a long leg longer than the short leg, the short leg extending from the long leg at an angle to the long leg, and wherein a first end of the long leg is coupled to an inner surface of the enclosure and extending inwards relative to the enclosure and the short leg is coupled to a second end of the long leg inwards of the first end of the long leg and extending inwards relative to the enclosure.

An airflow system for a genset, the airflow system comprising:
- an enclosure;
- a fan configured to drive air into the enclosure;
- and
- a plurality of louvers coupled to the enclosure, arranged in a louver assembly such that each louver of the plurality of louvers is structured to form a first path for the air driven by the fan to be directed in to the enclosure, and a second path for sound to be directed, from inside the enclosure, along the louver assembly in multiple directions, out of the enclosure, wherein each of the first path and the second path further comprise defining a path which restricts direct movement into and out of the enclosure, wherein each louver includes a short leg coupled to a long leg, the long leg being longer than the short leg, and wherein a first end of the long leg is coupled to an inner surface of the enclosure and extending inwards relative to the enclosure and the short leg is coupled to a second end of the long leg inwards of the first end of the long leg and extending inwards relative to the enclosure.
