Guardian 45-150kW Guardian Generac 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 some of 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 come standard with aluminium enclosures for superior protection against salt air and other corrosive environments. Aluminium enclosures, combined with Guardian's superior paint system, keep QuietSource generators looking like new for years.
