Natural Gas Mobile Generators 
The GN 165 mobile generator 
is a prime power workhorse 
for all your natural gas fueled 
applications. Natural gas provides 
a lower emissions footprint and 
lower fuel cost when compared 
to diesel. The lower operating 
cost is especially true when 
locally produced gas is available, 
for example, directly from the 
wellhead. Powered by a spark 
ignited heavy duty engine from 
PSI, the GN 165 is EPA certified 
for mobile off-road applications.
