MMG55FH Mobile Generator
Highly Mobile 3-Phase Power
The MMG55FH Flip-Hood diesel generator provides reliable 3-phase power where and when you need it, in a unique Patent Pending designed enclosure.
With its two Flip (front & back) Hoods you can easily access for quick field maintenance or back at the shop for full routine maintenance. Not only does it give you more room to get in, but its innovative open design brings more light into the areas that use to be so dark, cramped and inaccessible; designed to get it back into rental faster to give you the best return on investment.
