Sound attenuated enclosure
The aesthetically appealing enclosure incorporates
special designs that deliver the quietest generator of its
kind. Aluminum material plus durable powder coat paint
provides the best anti-corrosion performance. The
generator set enclosure has been evaluated to withstand
180 MPH wind loads in accordance with ASCE7-10. The
intelligent design has removable panels and service doors
to provide easy access for service and maintenance.
