Air Diffuser Nozzle

[bayou dude]

Does anyone know where I could buy about 200 of these adjustable high velocity diffuser nozzles? We are using them in window defogger systems for Marine vessels.The inlet is 3" in diameter. Any help is appreciated. Thanks!

3 inch is pretty small, usually that kind of diffuser is 6 inch and up. Search 'punkah louvers'

Here are some smaller ones, not adjustable http://www.airconceptsinc.com/products/punkah/iao.html
