Guardian QuietSource™ 18 – 45 kW Standby Generators

GUARDIAN 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 Guardian's superior paint system, keep QuietSource generators looking like new for years... even in coastal areas.
