The Derale 16836 Powerpack pairs two high-output 12" electric fans with an engineered aluminum shroud for strong primary engine cooling. Each fan uses a 300-watt motor, and together they move 4000 CFM. The raw aluminum shroud includes stator flow directors to straighten and boost airflow, and it can be left as-is, polished, painted, or anodized. Adjustable mounting brackets with complete hardware make it easy to fit to a radiator.
