It comes with 8 skewed blades, moving 500 CFM at 0 static pressure while drawing only 4.8 amps. Includes mounting kit and illustrated installation instructions.

The fan on my Derale 20561 broke on me and I reached out to Derale and they said this was a direct replacement for the fan. So i was able to keep everything attached and remove the old broken fan and install the new one and rewire it.

Not sure why paying this much for a small fan when there are others just like it for less. I wanted the more open design in the pic because I thought it would be lighter since I'm using it as a pusher fan on an AC condenser to help when it's hot.Other than that it's quiet and seems to work well.

Fan is not what is advertised. Correct fan ordered and received but even the Derale packaging shows a different version. Description wrong, packaging wrong, picture wrong, did Derale put the right fan in the box? who knows as there isn't any model number stamped on the fan itself to verify. Fan is a straight blade fan. Buyer beware! Should work fine but its a guess what is right, come on Derale get it right!

Awesome little fan. You can't go wrong with Derale. Used it as a supplementary fan on my radiator, to help the main fan. I also have one on my power steering cooler. Not too loud, but loud enough to know it's on

I was a direct replacement of the fan on my Derale trans cooler. It appears well made.
