The Derale Powerpack pairs two high output 12 inch RAD electric fans on an aluminum shroud sized to fit common radiator cores for primary engine cooling. The two fans move 4000 CFM combined through a patented ultra quiet skewed blade design driven by 300 watt motors, and stator flow directors help channel the air. The raw aluminum shroud can be polished, painted, or anodized, and adjustable brackets provide multiple mounting options for a precise fit. The fans are for puller (engine side) installation.
