Quietsource Air Cooled Natural Gas / LP

Quietsource Home Standby GeneratorThe Quietsource Air Cooled Models are the newest and most exciting addition to Guardian's 2006 product lineup. These models produce a full 16 kW when powered by LP vapor (15 kW on natural gas fuel) - the highest power of any air-cooled home standby generator on the market today. The air-cooled Quietsource generators combine the proven OHVI engine with an electronic engine governor in either a steel or aluminum enclosure to make a uniquely capable product. Quietsource air-cooled generators feature Generac's proprietary Whisper-Test feature, which runs the engine at a lower speed for weekly exercise. The lower speed means that the generator is quieter during its weekly exercise - only 61 dB. The Quietsource air-cooled generator is mounted on a composite mounting pad, for easy installation with no concrete pad required. Quietsource generators are available as generator alone (for installation with a Generac RTS Automatic Transfer Switch) or as a prepackaged unit with a 16 circuit emergency load center.

All Generac Guardian automatic home backup generators require natural gas pressure of 5-7 inches of water column or LP vapor pressure of 11-14 inches of water column.

All Guardian products include a two year warranty from Generac covering parts and labor and are UL Listed 2200.
