Radiator Fans with 20 Inch Diameter for projects

Working on a street rod or heavy-duty truck? 20 inch diameter radiator fans balance coverage with shroud fit for builds that need strong cooling area. Pick rigid blades for maximum airflow at higher RPMs, knowing they add more drag, or go flex where blades flatten at speed and are slightly deeper than rigid styles. Measure your space and run a shroud to funnel air, keeping clearances in check for best results.
Not effectively. Even though the blades could spin either way, a pulley-mounted 20 Inch Diameter fan is intended to pull through the radiator, not push. Set it up as a puller with a shroud to direct airflow. Without a shroud, cooling gains may be minimal.
