Derale Electric Fan Brushless Powerpacks

Get complete control of your engine temperature! Derale has combined their high-performing shrouded brushless Powerpacks with the ultimate fan controller. Using a brushless electric fan incorporated into an engineered shroud, this Powerpack can conquer even the most difficult cooling conditions. The PWM fan controller comes with built-in soft start technology. The controller utilizes Pulse Width Modulation to constantly adjust electric fan speeds from 0-100%, to maintain 185°F temperature. No more reacting to the engine temps, you can control it! This allows the 17" brushless electric fan to operate at the percentage needed, instead of 100% all the time, therefore increasing component life and eliminating amperage spikes. Show Less
