Apparently it's available as a replacement part!

Here is a link that might be useful: here

Listen to the fan before you install it. You are buying it for its ambiance and not for its sone rating. Dad installed one behind his range back in the 1960s. Vented it into the garage (not recommended).

I suggest one of these vintage ones on the ceiling and a newer vent above the range. I sure miss mine that matches this one you posted, now that it's gone! It's wonderful to be able to address burned toast, range disasters, heavy humidity before they head into adjacent rooms.

(1) If you use the larger 10" one - they are loud as heck and only partially effective despite being 550 cfm!
(2) If you use the small one - quieter, it's only 180 CFM. Smaller than most hoods, it will perform worse because it doesn't have a "capture area" so it needs to pull most of the air out of the room and doesn't have the motor to do it.

I'm sad to say that we still have two of those IN BATHROOMS. I've never liked sitting next to an airplane's wing and these fans are just like that.

If you're smitten, see if you can creatively clip this screen /face over a quiet fan assembly.

HTH

I *love* the Nutone! *sigh*

However, the bad issue in a modern kitchen (besides the noise) would be the collection of gunk on its blades that can't be easily removed.

Vent-Axis makes a modern version that can be dismantled for cleaning in the dishwasher, apparently:

Also, if you really love the look, Laurelhurst makes custom wall fans and grilles, although last I recall they aren't rated for kitchens:
Laurelhurst Retro Fans

Installed as is with no grease collection system, they would be a FIRE HAZARD and I'm not sure that any code inspector anywhere would approve it.

I've seen circular grease filters that fit into them, but I don't know how readily available they are. I have also noticed that with some of the extant ones I have seen, that they must be drafty because people seal them off in the winter. I looked at a house with radiator heat that was blistering hot, but the kitchen was noticeably cooler around the range area.

I would do a range hood (maybe a hidden insert) and then use one of these for the look if you really wanted it, mounted outside the grease capture area (Laurelhurst shows this on their site). BTW I think Laurelhurst may no longer be in active production (?) and just selling off existing inventory.

Hmmm....I've actually been mulling installing one of these in my master bath, which currently has no exhaust fan. My thought was that it might be helpful to turn on while in the shower in winter or summer when opening the window was undesirable (either for cold air in or letting cooled air out).

A more conventional exhaust fan that I could/would run both longer and more frequently doesn't seem essential because, A) the room is large and the bathroom door frequently open, so steam disperses quickly and well. And B) there are multiple extremely old, extremely leaky windows in the bathroom which do an unfortunately good job in ventilating the room!

Does anyone know if they have a way to close them off when not in use?

I remember having this when we lived in military housing years ago. As others have said they are really noisy. I remember them being drafty, too. Cold air leaked in, and it seemed it rattled like crazy when it was windy outside. Of course, that was a long time ago, and I'm sure they've improved.

I think if I remember correctly, when off, these don't seal well and the heat loss is great. Just as Joyce6333 mentioned.

Could there be a way to install a modern fan with this older face on it?

I remember my folks had one of these in the ceiling of their kitchen. I kinda remember it being noisy but it's been years since I heard it. In the winter my Dad would cram the cover plate with plastic bags and paper towels and everything else he could find to try and seal it off. I do remember my mother trying to clean the thick grease off it, too. And oh yeah, the ceiling was always greasy and dark around it. *bubble pops*

Okay. Maybe it's a pipe dream. Just so cool looking. I will check that link, Circus.

In old kitchen we vented our ceiling fan much like that one into the attic--a mistake. You need a channel all the way to the outside of the house. We always had ceiling paint peeling in a circle around it --we're in a cold climate. Additionally, it facilitates the building of an ice dam on eaves of roof.

To clean it, you remove the whole unit from the ceiling and soak it in ammonia and detergent. Been there, done that. Or just leave it and let the dust cling like fuzz to it.

But it does remove the smoke from burnt toast episodes!
