GPU

Granite Air Center has recently upgraded our ground power units to include a Hobart diesel powered GPU which will support all of your DC power needs.

​

​Our second GPU is an electric Hobart unit. This GPU provides precisely regulated 28.5 volt DC service with minimum noise. The unit allows for quiet operation as well as ground power availability inside the hangar so pilots can set up databases and flight plans in the warm hangar on those cold winter days.
