MCI 9 Air drier?

[luvrbus]

Jason, some say 8 ft but I don't buy it my Eagle had a AD 2 mounted in the engine compartment it was there since 1974 and never was a problem and was easy to service.Since you are changing to a AD 9 I would move that sucker the AD has all those bolts to remove to service it

good luck

Pay some respect to the Bendix installation minimum pipe lengths between the compressor and the drier.

It's about heat dissipation out of the compressed air.

Heat shortens desiccant life, sorta defeats the purpose...?

And, all downhill run, no loops, or you'll be on here crying about a freeze up in winter...

happy coaching!

If you worried about the length buy a Mertior/Wabco like the Prevost uses all they want is 12 inches from any excess heat,and they are just as good as a Bendix dryer IMO,also the Haldex is another good dryer.You are not married to Bendix both the above just want a slope from the compressor to dryer and mounted 12 inches from a heat source like the exhaust

Dryers in transport trucks aren't even 8' from the compressor, only a couple feet, or less, just down hill. They work good.

Mine is going to 5 ft at the most from the compressor but I am not going to worry about it

If at all possible I will try and keep it were it is. I stopped at the supply place and measured a AD9 and they are 9" round so hopefully I can make it fit.

Sounds like you have the new 50 choice in the engine bay Jason, I wasn't sure what you were putting in there so thought that 4 line dryer vid may be of interest. But pretty sure that your detroit is running 3 line with a tu-flow probably.
I will admit with head down in my early wrenching, of the same fleet I did not know the best practice was changing these dryers cartridges annually. So with that said and that I started occupying a chairs with other techs, for brake classes n burgers in the early 90's put on by suppliers in the area garages.  
I do remember some time ago copper/hard pipes were used and mandated a length/with reasoning coming off the compressors. Now days were seeing some special hoses attached to them so I think keeping that first foot or whatever length it is, in factory similar product is a good idea also.
I cannot recall the dryer part number as they have several available now, but I do like the spin on dryer cartridges,  guys these are worth taken a look at if updating.
The times changing these older ones I really found removing the whole thing was best method as a cleaning of the crap in the base was needed and easier around the parts washer, and I have honestly change a lot of them. ( because I was the only one called out in 2' snow ) and then ask why!

The ad9 and ad4 are same size basically and mine is running the 4 and plenty room. I will say Jason the round part is probably 9 but the aluminum base is a bit more with needed mount so could use a bit more room. will try a measure in a bit

Good day there

Well I just got under the bus to look and see if I have enough room for the AD9 drier and there is lots of room to mount it the problem will be in the lines as they are short and go straight up into the floor area that you can't see, so if they don't line up witch is most likely with my luck I'll have to some how connect onto them with some sort of fittings.

Is similar to the one I have. Mine requires no maintenance, it works without desiccant. - Very nice. I get no water in my tanks. Every time I drain them, nothing but dry air comes out. 

My 'wet' tank has a Bendix DV2 Automatic Drain Valve on it, so the pair of them are doing a great job. 

Good luck with your replacement.

Jason when i have lenghten or move copper lines I use bendable copper and make my own flares.
