The two speed 265 watt fan moves 2100 CFM on high and 1500 CFM on low through a patented ultra quiet skewed blade design, and the compact low profile allows a precise fit in tight spaces. The raw aluminum shroud can be polished, painted, or anodized. The fan is for puller (engine side) installation.
