I have the Guardian 5885 17kw generator. Air intake for the engine is on the right side, and exhaust comes out the left side. There is a vent in the back. I'm curious about its function. Does anybody know? I have a shed roof over the generator to protect it from rain and snow. Am thinking about adding some acoustic panels to cut down on noise, but obviously I don't want to restrict airflow.

In a related aside, does anyone know the air flow cfm through this unit? It has the GT990 engine. I'm talking about air flow through the right side and out the left.

The louvers in the rear are for getting rid of hot air from around the engine. The exhaust gas does not go though that vent, though.

MAKE SURE that you keep your shed roof AT LEAST four feet above the generator's housing and that you do not put ANYTHING within the required clearance distances shown in your installation manual (three feet clearance at each side and front and 18 inches at the rear). These clearances are the minimums mandated by NFPA 47 and NFPA 70 codes.

The rear vent is for the altenator. I beleive it is an air intake.

The rear intake admits cool outside air to the rotor/stator. If you look inside the cabinet you will see a duct that is bolted to the stator that is sealed with a foam gasket to that opening. The engine fan pulls air in the right side, and the left side fan pulls air through the R/S and pulls/pushes all the heat from both, along with exhaust gases, out the left side. The only air the R/S gets is from this opening as it is bolted flush to the rear of the engine.
