Generac MMC 2.5FG Engine UL 2200 Listed CSA Listed Power Matched Naturally Aspirated
QuietSource 20 & 25 kW
Progressing in power from the 11 kW model, the liquid-cooled line of QuietSource generators make available environmentally quiet operation while resisting corrosion. Combining an air-channeling designed enclosure with sound-deadening materials make these some of the quietest liquid-cooled standby generators on the market. And because of the all aluminum enclosure, these units are also corrosion resistant to keep up their good looks over the long haul. Units run on either natural gas or LP gas.Standard Features
- Built-in charger maintains battery at optimum performance level.
- Automatic safety shutdowns protect engine and generator in event of low oil pressure, low oil level, low coolant level, high temperature, overspeed and/or overcrank.
- Automatic seven-day exerciser runs the system for fifteen minutes each week to maintain top running condition.
- Transfer switch options are available in 100 amp or 200 amp sizes
Sound Attenuated Enclosure
- Engineered air-channeling and sound reduction design
- Sound-deadening material
- All aluminum
- Corrosion resistant

FEATURES
INNOVATIVE DESIGN & PROTOTYPE TESTING are key components of GENERAC’S success in “IMPROVING POWER BY DESIGN.” But it doesn’t stop there. Total commitment to component testing, reliability testing, environmental testing, destruction and life testing, plus testing to applicable CSA, NEMA, EGSA, and other standards, allows you to choose GENERAC POWER SYSTEMS with the confidence that these systems will provide superior performance.
TEST CRITERIA: >PROTOTYPE TESTED >SYSTEM TORSIONAL TESTED >ELECTRO-MAGNETIC INTERFERENCE >NEMA MG1-22 EVALUATION >MOTOR STARTING ABILITY
SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE REGULATION. This state-of-the-art power maximizing regulation system is standard on all Generac models. It provides optimized FAST RESPONSE to changing load conditions and MAXIMUM MOTOR STARTING CAPABILITY by electronically torque-matching the surge loads to the engine.
SINGLE SOURCE SERVICE RESPONSE from Generac’s dealer network provides parts and service know-how for the entire unit, from the engine to the smallest electronic component. You are never on your own when you own a GENERAC POWER SYSTEM.
GENERAC TRANSFER SWITCHES. Long life and reliability are synonymous with GENERAC POWER SYSTEMS. One reason for this confidence is that the GENERAC product line includes its own transfer systems and controls for total system compatibility.
