Abstract: An enclosure for a generator includes an air inlet formed at a first end of the enclosure, and an air inlet opening formed in a sidewall of the enclosure. The air inlet includes an air inlet duct formed in an interior space of the enclosure, and in fluid communication with the air inlet opening. The air inlet duct receives the airflow from the air inlet opening to direct the airflow towards an air outlet of the enclosure. The air outlet includes an air outlet duct formed at a second end of the enclosure which receives the airflow from the air inlet opening. The air outlet duct directs the airflow towards an air outlet opening formed in a top plate of the enclosure which provides an exit for the airflow to escape from the interior space to an ambient environment of the enclosure.

Abstract: A reduction device includes a housing defining an input chamber configured to receive exhaust from a power source, an output chamber, an exhaust channel configured to direct the exhaust from the input chamber to the output chamber, and a longitudinal axis. The reduction device also includes a treatment unit disposed in the exhaust channel and along the longitudinal axis. The treatment unit is configured to at least partly remove pollutant species from the exhaust. The reduction device also includes an attenuation component disposed in the housing and radially outward of the treatment unit. The attenuation component is fluidly connected to the exhaust channel, and is configured to attenuate a range of frequencies corresponding to operation of the power source. Additionally, the exhaust channel prohibits exhaust entering the input chamber from exiting the housing without passing through the treatment unit.
