The Derale Powerpack mounts a single high output 17 inch two speed RAD electric fan on an aluminum shroud for primary engine cooling. The two speed 265 watt fan moves 2400 CFM on high and 1800 CFM on low through a patented ultra quiet skewed blade design, and the 3 inch overall depth allows a precise fit. The raw aluminum shroud can be polished, painted, or anodized. The fan is for puller (engine side) installation.
