Suggest a more appropriate thread.
Meanwhile ... Read the Manual ... the fans vary from year to year and model and length but I would think that your dealer would be a good source of info for what you just purchased ... my wife enjoys reading the manual to me .... back to ducted air now.

Ducted Air

Someone posted this in another thread and I figured other ducted air owners would be interested in seeing it. They were shown in a new "2015" Classic Twin model video. Looks like a retrofit could be easy.



Directional vents that also allow you to close.

Also it looks like they are mounted on some type of flex tube. In the video you can see the one he touches moving around and the rings on the one in the foreground.

After 4 trips - outside air temperature ranging from 85 to 32. My Ducted Air system works flawless .... Directional vents are unnecessary. Air is distributed throughout the cabin in perfect harmony, the temperature is constant from the head to the tail. So if the temp is not right, I just adjust the thermostat. Anyway... this works for us.

Completely agree ... as I have advocated for the ducted air all along ......since last July ! It was the reason we traded in a 2013 EB to get the ducted on the 2015 EB - everything else is exactly the same ...

I'm considering a 30' Bunk with the ducted air. Looking at the attachment, it seems that both AC units are connected to all of the ductwork in the trailer? So if one unit is on it blows throughout and if the second unit is fired up it only supplements?

Also, does anyone have a 30' bunk with the ducted air? I see two air ducts directly over the bunk. Is that problematic? Do they blow too much? I suppose they could be blocked off a bit but just wondering.

The ducts, there are two long tubes from front to back on either side of the trailer, are one long run. So your comments about what happens is correct.

The latest Classic model now has outlets that can be shut off and swiveled for direction. Wonder if that will trickle down to the rest of the line or be something that could be retro fitted?

Funny, how everyone else in the industry has no problems with the drains of their A/C units........except Airstream!

Lew,

I did notice that zone 2 has a pretty good rattle (low frequency noise) on HP startup and a decent vibration (higher frequency noise) when running. I actually started pressing up against the interior roof in various places and finally got the vibration noise to settle down audibly but you could still feel it.

Given the apparent tendency for the units to leak and rattle due to the new drain design (1 gasket, small drain cups), is this something I should complain about hoping that Airstream will remedy it or should I order the old style pan and gasket(s) and have them changed out as switz did? Is this a big deal and/or does it potentially open a can or worms if not done correctly by the dealer?

Or perhaps I should argue that it needs two gaskets per the manufacturer period, though in the past on similar "non-compliance with manufactures' specifications" it has never gotten me any where at all.

ANY OTHERS WITH LEAKS AND/OR RATTLES??

I have it scheduled for service Feb 2nd so maybe I should bring it back to the shop and see if I can get the startup rattle and running noise recorded on my iPhone and then send it off to Airstream and review with the dealer.

I did the RV550 swap out myself in order to insure it was done correctly but not sure about getting on the roof and man handling the AC units.

Follow up to other thread comments, the Dual AC ducted air is a significant improvement over the single AC non-ducted in my 2012 25FB. Overall it is significantly quieter, heats and cools better/quicker (even only running 1 zone), the heat/cool is more evenly distributed and the interior of the roof is cooler in direct sun. It was a significant factor in our trading up and is well worth the increase in cost.

Thanks!

Leaks and rattles caused by the use of a single A/C gasket will disappear when a second gasket is used AS DOMETIC SPECIFIES!!!!!!

Once the roof A/C gasket has been compressed from mounting, you will need to remove the original gasket and replace with a new gasket and then add the auxiliary drain kit with it's catch cups, included drain line, second gasket and additional solid foam blocking. The instructions are very specific and easy to use! Remember, that the recommended compression of the gaskets is 50% of original thickness.

To get a good seal at the outer edges of the A/C unit, you will need to actually exceed this at the center of the A/C unit, but it will work regardless, as I have never had a leak using this mounting method. Just finished replacing 2 roof units in an old Bluebird Wanderlodge that had more roof curvature than Airstream trailers have, and the water hose test after installation, along with the torrential downpour 3 days later showed not a drop of leakage to the interior of the bus.

I would not count on the factory doing this for you. It is fairly easy once you remove the unit from the roof and turn in on its top (use a heavy moving blanket as a cushion). This will give you perfect access to the bottom of the A/C unit to remove the old gasket, apply the new ones and then install the drain kit.

Lew,

Thank you very much for the quick reply. So you would recommend sticking with the current plastic cup design reinstalled properly using the two gaskets over the older style pan and thicker gasket.

No issues with the plastic cups?

Would you have a link handy for the installation instructions?

Hi FB,

I don't, as I have done so many that it is almost a reflex action by now.

You might check on the Dometic USA web site to see if they are posted there.

Many other RV manufacturers have been using those drip cups for years with no issues.

Do the ducted air models have any inside access to the AC units for maintenance issues?

Directional vents that also allow you to close.




Here is the response from Airstream for a part number on the Grills.

"Hello, I contacted our parts department and they gave me this part number for those grills. 382233-02"

Now to find out how much??

Wow! These are great! Especially for over the rear beds in the bunkhouse... I will see if I can order some.
