Spal 30103202 12 Inch Curved Blade Puller Fan - High Performance Cooling Fan for Automotive, Marine & Industrial Applications

Excellent cooling fans! Really move some air. I'm using 2x of them on a lifted mud truck. The original mechanical fan kept getting bent up by mud and rocks. They do draw a TON of current, more than 30A each. Needed a 120A relay to power both. Most cheap fan wiring kits out there will not work. I actually had to install a larger alternator to power both! Now I can shut fans down BEFORE I go through a mud bog, and turn them on to quickly cool it down when I get out (if I get out?). Other electric fans I tried just didn't have the balls...these do!
