I'm wondering what this type of fan is called because i need to replace one in my projector, it has a plastic casing with a shoot so the fan blows the air out of that shoot as shown in the picture.

Answer 1

It's called a squirrel cage blower but you should simply be able to ask for a fan. You didn't mention the make or model number so I can't direct you to any websites but if it's still under warranty you'll want to contact the manufacturer.
