SPAL's revolutionary, custom programmable fan controller allows a single SPAL cooling fan to vary speed based on engine temperature thereby increasing fan life while decreasing under hood noise. The FAN-PWM also utilizes the OEM water temperature sensor eliminating the need for a second sensor. With an air conditioning input, secondary fan output, and waterproof aluminum construction the FAN-PWM is the perfect addition to any SPAL cooling fan.
