Diesel Generator Selection Guide

HOW TO SELECT AN AURORA GENERATOR

AURORA manufactures diesel generators for a variety of applications. At the core of each generator set are the engine and alternator. We use only world-class Perkins Engines and a variety of the best alternators. Add a few essential components like a muffler, vibration mounts, and some engine control, and you have what we call a bare-bones generator. At the other end of the scale, is our Residential and Commercial diesel generators. Fully customizable complete packages ready to use.
