MQ Power Ultra-Silent Power Generator



The next generation of WhisperWatts™, boast even lower noise levels than MQ Power’s industry-leading soundattenuated units. With sound levels from 56 to 63dBA full load at 23 feet, the generators are up to 11 decibels quieter than the current WhisperWatt™ line. Each Ultra-Silent Series generator features our patented air flow design, making them the quietest power sources on the market. In fact, your everyday conversation is louder than these new models.

		MQ Power is the obvious choice for dependable portable power. With a full line of diesel-powered generators from 7kW to 2000kW. The Ultra-Silent Series generators are the new revolution in portable power, lowering quiet to a whole new level. They’re up to 11dBA quieter than our industry leading WhisperWatt™ line and make less noise than your average conversation. In addition, they’re environmentally friendly with full fluid and fuel containment systems, and offer exceptional voltage regulation.
The Ultra-Silent Series features an upgraded environmental package with an integrated fuel tank and fluid containment system, improved fuel efficiency and voltage regulation, and residual value that is unmatched by any other generator. There are six single/three-phase models in the Ultra-Silent Series with outputs ranging from 25 to 150kVA. All are engineered with an integrated 24-hour fuel system and come standard with Tier II EPA-approved engines. A new patented airflow design reduces sound to the lowest levels ever. That’s guaranteed to impress even the most demanding customers.
