Get complete control of your engine temperature! Derale Performance has integrated their high performing shrouded Powerpacks with the ultimate fan controller. Using a high output electric fan incorporated into an engineered shroud, this Powerpack can conquer even the most difficult cooling conditions. This unit features a Aluminum shroud measuring 20-3/4" wide by 17-5/8" top to bottom and is only 3" in overall depth to offer a precision fit. This 17" high output two speed fan is one of the best in our line-up offering up to 2400 CFM and is specifically designed to thrive on thick, tight fin radiator cores.
Now add the integrated PWM Fan Controller with built-in soft start technology. The controller utilizes Pulse Width Modulation to constantly adjust electric fan speeds from 0-100%, maintaining the optimal engine operating temperature. No more reacting to the engine temps, you can control it! This allows the 17” electric fan to operate at the percentage needed, instead of 100% all the time, therefore increasing component life and eliminating amperage spikes.Specifications: CFM high/low: 2400/1800
