Air filter

Coachman 2006 Encore Caterpillar c7 330 hp w/ turbo charger, Freightliner Custom Chassis. I'm sure this topic has been covered before but after much reading I can't seem to find the answer. I've learned there are two types of air filters used, a canister type #P533930, and the type I've pictured below. I've not found a part # or manufacturer for this type. I'm also confused about fuel filters. I've heard reference of a primary, secondary and a fuel/water separator. Are these all different? We bought this motorhome last fall and will become full timers when my wife retires from teaching this July. Am trying to get my vehicle ready for life on the road. Any help will be appreciated.

Check this site for your filters,Primary is "usually" also the fuel/water separator filter.
Diameter, length,opening sizes will tell you what filter for the air,check filter with a mirror and try to get a number off it.

The type pictured is a Farr Ecolite style filter.

They can be purchased as Wix, Baldwin, and a variety of other brands.

Very common in MH applications.

Depending upon the coach builder, you have either a single fuel filter or a primary and secondary fuel filter. The primary is the water/separator filter in this application.

If you only have a primary filter, it is the water separator filter.

Not a CAT owner, but I think this information is correct. IF not someone will chime in.

Looks like an "ECO" air filter, not sure which one fits your chassis. Call Freightliner Help Line 1-800-FTL-HELP (1-800-385-4357) with your VIN number.

The fuel filters- some are just filters and some are combined filter and water separator. Again Freightliner should be able to tell you what came on your chassis.

Freightliner has publications here. Freightliner Motorhome Chassis ? RV Chassis

"Knowing your RV chassis" and the maintenance manuals are shown or the right side and are free to download.
Hope this helps.

I googled 'eco filters' and there are a lot of hits for it.

Here's one:


They are marketed under a lot of different brand names. Any NAPA dealer should be able to supply one.

Take a look all around your filter cannister. When I removed mine, there was a large data sheet on the back side of it with the brand (Eco) and the part #. I gave that info to our local auto parts store and they ordered it in for me.

I purchased my air filter and others for my C-9 at Rvchassisparts.com. The air filter wasn't to bad to replace I removed clamps and gently broke the seal with a screw driver careful not to tear and it pulled off. To put it back it got everything ready sprayed the inside of rubber pipe with silicone and slide it back on.

It's a Farr Ecolite, same as used on our DSDP although there are different sizes and air flow specs. Larger canisters flow more air in most cases. The intake and exhaust can be switched for different applications.
Due to the rubber piping getting brittle and not being able to be sealed the rubber should be replaced when changing the filter. Not my determination, that advice comes from a retired filter engineer

My air filter is the same as yours, last year it was $67 out the door at Freightliner. Napa wanted almost twice that, not sure why.

Thanks for the great info. I probably would have gone to NAPA.

At any rate, change it so you know what you have. FR dealer emphatically stated change every two years, regardless of use.
They seem to have a nasty habit of disintegrating from the inside after a couple years, thus, causing a condition known broadly as "dusting" the engine.
Often this necessitates an expensive rebuild...the filter, even at NAPA prices is cheaper...
