Air Dryer desiccant cannister

The PO had the desiccant cannister in his box of random parts. He also had what I believe is the coalescing filter, along with some other random parts in a bag together. I attached a photo of the random parts and what I believe is the coalescing filter.

Maybe someone can identify the other parts...maybe for the aqua hot and not the dryer??...and confirm that what I have is the coalescing filter...don't want to get it apart and not have everything I need.

Wish he would have had this stuff labeled better.

Also, can I replace the cannister and the filter easily? Leaving on a trip tomorrow and don't want to get into something too deep. I popped open the air water drain yesterday and only air came out so I think my air system is fine and can wait until I get back to do this. But if it's as easy as spin off the cannister, install the coalescing filter and spin back on the cannister I'll do it...though not sure if there might be some o-rings to replace or other parts.

The Danfoss nozzle is for the Webasto burner in the Aqua Hot.

The canister and filter are for the air dryer.  The other parts are probably for the air dryer which be evident when you replace the dryer.

It's as easy as you suggest. Use an anti-sieze thread compound when reapplying the cannister and only go a little past hand tight

As others have said those are the right filters for that dryer, BUT that is only half of what you need to service that Pure air plus.  If you don't have the DQ6020 kit to rebuild the bottom half, you are best off to leave well enough alone till you can get back from your trip  and have time to do the job correct. If you don't do the bottom half it can leave you setting on the side of the road even with new filters.

That's what I was worried about, thanks. You just freed up some time so I can squeeze in some other last minute ill advised projects.

One other thought about that dryer element. With it being open to the atmosphere for no telling how long I would at least put it in an oven and bake it at about 120* for a couple of hours. This will dry out the activated aluminum that is the drying agent inside if I was going to use it.

Mike raises a good point, and also - do you know when the previous owner last had the air dryer serviced?

If the cartridge is old/you don't know the history of it, it may actually be worthwhile doing a factory-reman'd air dryer in its entirety.  There are a few posts on it - you want to get the reman'd unit first (pay the core charge), do the swap, then return the old air dryer for a core charge refund.  This way you know the heater, valves, etc. are "new".  You'll need to harvest some fittings/bits from the old air dryer, which is why it's best to use the buy-replace-returnforcorecharge sequence.

Of course if the previous owner gave you records, you may not need to do the above.

Thanks for the recommendations...I'll look into the reman kit.
As far as the cannister, It had a thick cellophane wrap around until a week ago and stored under the coach in a plastic tub...think it's still ok? It's at least 2 years old but might be 5 years old or longer 🤷

Just an observation, albeit 10 years old.  Jim McNeece did a cost comparison on the major+minor rebuild kits versus a Haldex factory (not 3rd party) reman'd air dryer: 

Desiccant powder in air system - anybody else with this experience?

(You can see the havoc a failed desiccant canister can cause in this topic Pure Air Plus Air Dryer - An Ounce of Prevention... ...)

I believe the part number for the reman is DA33100X and most NAPA's can get you one.

Haldex air dryer service, what do I have?
