After installing squirrel cage fan for intake and bladed fan for exhaust, would it be adviseable or even necessary to have some sort of air filter either on the intake or both intake and exhaust?
I was thinking it may help to keep some dirt out of generator bay by means of intake and IF a filter was on exhaust hole it might even cut down on some of the generator engine noise, not that it is a lot without one!
Just curious!

I've never seen more than a bugscreen on the intake side.

I dunno... I'd worry about plugging up the filter...

I don't think a filter will do anything for the noise on the exhaust. Not enought right angles to make anykind of difference if your genny has any kind of loudness, and there wont be any reason to filter the exhaust. I doubt you have a problem with bugs getting into the coach from the gen exhaust.
I have seen a filter on the inlet but they accumulate a lot of road dirt fast. If you do this, you probably should find a way to monitor the compartment, like a temperature probe that you can watch. As the temp goes up, the filter is plugging.
Might be a thought if there is a reason you need to keep the gen box cleaner than normal, but if you don't have a big reason to be concerned, not installing a filter is just one more thing you don't have to watch and change later.

Not on my genset , but for my central basement A/C i use the green 'scotch brite' material - cut to fit the vent holes - doesn't filter all the dirt , but gets majority - they are very tough and reusable w/just a rinse their like new - and they are not to restrictive on the air flow -

The generator installation was rather quiet UNTIL I installed the bladed exhaust fan that came withe the set from Wrico. Only after I made the hole for the air to exhaust is when it apparently got a LITTLE not much louder. I was thinking if the hole had a filter of sorts it might cut down on some of the noise which is more air noise than engine noise! Just a thought!

Curiosity questions:
Where did you cut the hole for the exhaust air?
Could you put a baffle downstream a little to deflect both the air and noise?
Just thinkin' at the keyboard. . .

RJ the exhaust is directed from radiator which is about 2 inches from a bulkhead. The bulkhead has a hole in it going from generator bay to a forward bay. On that side is an air box or duct that I mfgr'd to direct air down, towards floor and that is where the air exits the bus, thru the floor! The air has to make a 90 degree to exit from radiator if that helps!

Between the radiator and the bulkhead, do you have the radiator shrouded?
And where have you placed this bladed fan? Does it blow thru the radiator into the duct, or suck thru it from the other side of the bulkhead?
Would it be possible to put another, short, 90 degree duct where the air exhausts under the bus, pointed toward the rear axle?
Again, just thinking at the keyboard. . .

Screens small enough to keep out bugs, wasps, bees, mice and cooties is a good idea, but a real type filture MAY restrict the air flow tooss much. |

RJ the radiator is mounted on a square metal box and the bladed fan is mounted IN this box sucking air from the radiator which blows out the hole thru the bulkhead into the next bay and down thru the floor. Yes I could add another shallow duct UNDER the bus floor directing it rearward if necessary!

Ace - how about lining the interior of your metal box with duct board (HVAC rigid type) - it works wonders for sound deadening at the squirrel cage on air handlers -

Yea Niles I was already contemplating that idea too! Thanks!

Ace, my Le Mirage has a filter for intake air for the generator radiator. It is the washable metal type, about 15 inches by 4 ft. It catches a lot of sand and grit but never restricts airflow enough to affect cooling. My air comes in from behind the front wheels. |

Thanks Steve! I was thinking onthe same lines but not behind the front wheels. My air intake comes from beneath the floor. I just thought some kind of non air restricting filter would keep a lot of debris out of generator and bay!
Thanks again and looking forward to seeing you in Arcadia!

If you have the room, you could use a centfugal or tornado type filter. Basically it just forces the air to rotate rapidy crating a vortex. The air in the outer vortex spins quickly flinging the dirt down and out of the funnel. These have been used for years in industry as prefilters in dirty areas. THe air coming out of them is generally clean enough that you would need no other filter. A side effect of it is that it is also inherently a muffler of sorts too. A bit of research on your part and a bit of sheet metal work will make you a fairly good system that never needs cleaning or maintenance. (except for a hose down from time to time, but not often.
