Factory installed LL dryer

Can't speak for their 410A systems but I am sure they probably do.

Even Lennox owned Aire Flo brand 410A system come with an LLD.

Not meant to be insulting, or offensive toward you in any way.

A filter drier rated to hold 400 drops of moisture. Can hold 20 grams. Its takes 28.35 grams to equal 1 ounce. So the above filter could hold .7 ounce(taking weight, not volume).

There are 16 ounces to the pound. A gallon of water weighs 8.33 pounds at 50°F. So that filter drier can only hold .0052 gallon of water/moisture.

The next factor that varies a filter driers ability to hold moisture. Is the refrigerants ability to absorb moisture(the moisture solubility of the refrigerant). As the refrigerant warms up, its solubility increases, and it will pull moisute from the filter.

Lucky, maybe, maybe not.

You may have seen the effects more often then you think, or know of.

That unexplained sticking/stuck piston at the evap. That clogged cap tube on heil/ICP heat pumps(and some other brands).
The clogged filter drier. Sticking rods in a TXV. A shorted compressor(even though there is no acid). the system with non condensables(some of that non condenseable is water vapor,).

There's more.

When you say the Aire Flo units come with a LLD, are you saying there is a LLD factory installed in the units, or that there is a LLD laying in the box that needs to be installed in the liquid line?

Good hunting.

If you know they make them. Post a link to that model liquid line/suction line filter drier. Or post the model number of the drier.

You're welcome to believe or not.

I got nothing to gain either way.

Even when i proved beyond a shadow of a doubt I am still taking guff for using CO.


For that reason I am not going to go dig up anything on this issue and take the chance of a bunch of yahoos giving me grief even after i have proven my point.

So believe if you like. Your life won't change either way but I at least won't get my character smeared again.
