Air Requirements
A fan on the rotor of the generator draws cooling air into
the compartment through the generator cooling slots
and expels it at the engine-generator adapter. The
engine of the generator set features an Air-Vact
reverse flow cooling system. Fins on the engine flywheel
pull cooling air past the fins of the cylinder heads and the
heated air is discharged downward and out of the
compartment through the discharge chute. See
Figure 6-15.
