Those look to a similar diameter to my heat vents which are just louvered so you can direct the air but not shut it off..

I’ll have to look at my heat vents. They are the directional ones too.

Go on Amazon they have a couple different kinds. Valterra vents seem to be the best. Be sure to measure the cut out because there are two sizes.

Hi. I will try and explain what those vents are supposed to do. This may help you with what you have now.

Those ceiling vents do not per say, direct the cold air. They are made to balance the AC air flow/volume in the camper. Screwing them in, CW, closes them to help choke the volume of air at that location. By choking off one area it forces more air to the other vents that are in line with it.

There are normally 2 main ducts up above the ceiling. One heads to the front and one to the back of the camper. Then in line in one of those ducts are several of those adjustable volume vents. Each main duct only has a certain volume of air leaving the main AC unit

If you have the vents closest to the AC unit wide open, then most of the cooling will be in that area and not much farther away. Again those vents balance the volume that the AC unit produces. If you put larger new vents in place of them, all the cold air will come out close to the ac unit. If that is what you are after, then they can help.

If you want to balance the amount of air to be even across the camper, start with them all only about 1/4” to 3/8” open and then let the camper cool down and the AC shut off. Then feel how even it is from one end to the other. Tweak the colder spots closed a little and open the warm ones a little. You only have so much volume to spilt up amongst the vents in the one duct.

In our bedroom, we do not want a large blast of cold air during the middle of the night, so that one vent is closed more then others.

Hope this helps.

John

Yeh, ours T310SR has 3 ceiling vents per air duct up in the ceiling for a 13,500 btu ac unit. I think the smaller campers with ducted air may have the same or 1 less per side.

If you choke the one closest to the ac unit it will force more air to the end ducts. They are made to blow out air 360 degrees around the ceiling.

Sensible actually..much like dampers on furnace ducts that most people are infuriated when find some of them partially closed..and then wonder why the rooms farther out are always cold ..
