2. Heavy-Duty Backup Power Protection
This generator is built to last, so you can enjoy years of freedom from the discomfort and costliness of unexpected
power outages. The automotive-style engine is designed for long-term use. Liquid-cooled and geared to run on natural
gas or LP (propane), this superior engine provides continuous power with reduced emissions.
Like all Generac generators, this model is UL (Underwriters Laboratories) listed for safety.
Looking for a generator with a slightly more powerful engine? Check out the 48,000 Watt Generac Guardian Series
generator.
Rugged Encasing Stands Up to Harsh Weather
Ruggedly enclosed in tough steel and protected by Generac's proprietary RhinoCoat system--a unique process that
binds the paint to the metal surface for a long-lasting, durable finish--this generator protects against debris and holds
up against the elements without developing an unsightly appearance. Plus, all components are easily accessible for
routine maintenance.
Quiet-Test Feature Means Whisper-Quiet Operation
Specially designed with Generac's patented Quiet-Test technology, this generator is ideal for environments requiring
super quiet performance. The Quiet-Test mode kicks on for an ultra-quiet, neighborhood-friendly self-test that's as
hushed as a car in an idle state.
