Window AC with 100% Recirculating Setting

[nealperkins]

I must purchase a new AC window unit for my walk-in with Coolbot.

I specifically am looking for a unit that allows me to defeat any introduction of 'outside' air. A few units seem to have a switch allowing this setting. I need 12,000 BTU's.

Would you know a brand and model # that allows this setting?

Thank you!

Pretty much all of them provide a recirculation function.
From a 29000btu unit down to a 5000btu unit in our house, they all have that function...

Cheers!

That has not been my experience with the two I now own. Earlier, I remember switches and/or dials for the user to select. But, now not so much.
Thanks

I have seen that setting on old units to allow outside air in. Most new units do not have this option and only circulate inside air.
