Vic says: 2 years ago Going on a second year with the freeze dryer. Considering getting another one. It really takes commitment, but it is very rewarding. The freezer is good also, but it needs constant source of electricity, and the storage is limited to the size of the freezer.

The only way I know to filter the water vapor out would be a cold trap. They usually use liquid nitrogen or dry ice to keep the temperature low enough that all the water condenses out. Obviously you would need a supply of the liquid nitrogen or dry ice that would probably not be cost effective for most of us. The other option to get that cold would be to use a cryocooler and build a cold trap around it. It could be done, but would be pretty expensive. I've been watching some electronics on ebay that have cryocoolers in them, but the cheapest I've seen is around $600. Still not a cheap option, but you wouldn't need dry ice or liquid nitrogen to feed it.

AN8 male fittings are 3/4 X 16tpi. Should be able to get one that will work in this application. Also, there filters that use metric threads, might be easier to deal with.

and this piece was placed on the vacuum hose fitting. I can still remove the panel without removing the hose to clean the coils. Simply remove the screws and slide the panel down the vacuum hose a few inches.
