Generac® QuietSource 22 - 48 kW Liquid-Cooled Standby Generators

Generac Standby Generator - 20-45kWGENERAC QuietSource generators are ideal for applications that require ultra-quiet operation and exceptional fuel economy. With larger and more powerful liquid-cooled engines that run at 1800 RPM under full load and our exclusive Whisper-Test feature, QuietSource generators are the quietest in the industry. In addition, these larger engines achieve greater power output with less effort, resulting in significantly reduced fuel consumption both during exercise and under full load.

QuietSource models also come standard with all aluminum enclosures for superior protection against salt air and other corrosive environments. Aluminum enclosures, combined with Generac's superior paint system, keep QuietSource generators looking like new for years... even in coastal areas.

  • High Displacement, Low Speed, Liquid-Cooled Engine: Provides ultra-quiet operation and exceptional fuel economy

  • Gray, Aluminum Enclosure: Superior corrosion protection for coastal communities

  • Whisper-Test: Low speed exercise feature makes QuietSource the quietest generators on the market

  • Superior Paint: Tough, textured powder coat paint finish for unmatched durability and all weather protection

  • UL Listed: For safety and certified power ratings
