I changed the air filter because there was a brand new one in the basement of my rig when I bought it, so I didn't know if the previous owner was getting ready to change or if he just kept one on hand.
The air dryer location is up to the chassis manufacturer on mine it is located right next to my fuel filter and water separator filter. The Air Dryer Filter is a stubby cannister that will spin off using a large strap wrench. The purpose of the air dryer filter/desicant is to remove possible moisture from your air braking system. I think most chassis manufacturers recommend replacement every three years. You can also buy after market filters but a lot are made in China or elsewhere overseas and for what an OEM costs you are only saving a few dollars so I buy the OEM brand.

I did just changed mine today. Quick and simple...only a screwdriver needed. I had maint records indicating it was not needed by mileage and the maint minder showed it to be good. With it being new to us.......I did it so I know what I have to start with.
Hats off to Monaco....so easy any "mechanically challenged" person could have done it.

Well I finally got around to change my cartridge air filter I've had for 2 months. It was the original filter yep 5 years old but 16,000 miles. Easy install if the inside looked as clean as the new one. It was one of those projects I was dreading and I shouldn't have fairly easy.

cmpncrsaider; The air dryer is 2 filters in a cannister that removes oil and water from the air brake system. Normally changed at 3 years (on my XCS chassis) (More often if you see water when you pull the air tank lanyards) Midland/ Haldex is usually the manufacturer.
Different models on different chassis-
Not a difficult DIY but very important to drain all air pressure from the brake system before working on the filter, or any part of the brake system....

Here is an article on replacing the "PureAirPlus" filters.

hope this helps

You might wish this but you don't have to worry about the seal around the filter like you do with a replaceable filter cartridge. Just get the inlet and outlet ends sealed and you're good to go.

I've got a guaranteed 4 year/100,000 synthetic air filter in mine that outperforms cellulose and wet gauze filters in flow,filtration and dirt holding capacity. If you provide me with a part #, I can cross reference and see if one is available for you.

The manual indicator attached right on the air intake are very reliable. They record (lock in) at the highest draw seen. I buy them a Catrepillar. Had a shop with a 300hp dyno and measured before and after HP on filters that LOOKED completely plugged and the guage indicated they were still ok. NO DIFFRENCE. Started the policy of never changing the filter until indicator was at 20. Saved the fleet $100,000 per year in filter cost only, not counting labor or premature engine wear. With operators blowing out filters and messing with them (looking) our silicon was way high. New air filter policy and silicon in oil dropped to the teens. For rigs that go 22 with a new filter. That rig needs to be reengineered.
