The Derale 66822 is a High Output Powerpack that combines a single 17-inch RAD electric fan, a raw aluminum shroud, and a PWM fan controller in one bolt-on cooling package. The high output two-speed fan is designed to pull air through thick, tight fin radiator cores, moving 2400 CFM on high and 1800 CFM on low. The included PWM controller varies fan speed from 0 to 100 percent for efficient, quiet operation, and the raw aluminum shroud can be left bare, polished, painted, or anodized to suit the build.

FAQ
What is the Derale 66822?
It is a High Output Powerpack that pairs a single 17-inch RAD electric fan with a raw aluminum shroud and a PWM fan controller for strong, efficient radiator cooling.
How much air does it move?
The two-speed fan moves 2400 CFM on high and 1800 CFM on low, drawing 23.5 amps on high and 17.4 amps on low.
What does the PWM controller do?
It varies fan speed from 0 to 100 percent based on temperature for quiet, efficient operation. It is rated to 70 amps and includes an auto-resetting circuit breaker, a built-in A/C override, and a 20-second shutdown timer.
What is included?
The kit includes the fan, raw aluminum shroud, PWM controller and sensor, plus mounting brackets and complete mounting hardware.
Is it universal?
Yes. The 66822 is a universal Powerpack and is not specific to any one vehicle. It measures 22-1/4" wide by 17-5/8" tall by 3" deep; confirm it fits your radiator before installation.
