Wide/long squirrel cage fan for blowing air upwards in a tent?

[Tompo]

Hi!

I have been trying to find a place where to buy these things for which I don't even know a name for.
I mean a very wide tube shaped fan that has the whole inner structure running and blowing air upwards, only seen once as one guy provably used such in one of his grows.

I would really appreciate any luck finding these things, or even a name they are called! =) A shop from EU would be perfect as an answer!

Here's an image of one:

Thanks!

Some luck, might have found the name for this thing:
"cross flow fan" or "air curtain", quite similar products but the first one seems more like the one in the pic.

Anyone have experience with these things?

Edit: actually, these are tangential fans. Just how the heck to find one that has the blades behind that grid, my poor fingers would become minced meat otherwise

What model fan is that. I need one myself. Anyone find out?
