FHK-1000: AirDog® Positive Temperature Coefficient (PTC) Heater Kit

The AirDog® Positive Temperature Coefficient (PTC) Heater is an extra step of thermal protection for all AirDog FPII-150 and FPII-200 4G fuel air separation systems, to help prevent the fuel system from gelling in cold climates. This kit features a top-of-the-line 300W heater element, manufactured by Fleetguard (Cummins Filtration). This heater system provides a simple solution, to add heat to your fuel system. The PTC fuel heater is an electric, self-regulating, and self-protecting heater. Power to the heater varies by temperature, and it requires the minimum current and does not need any additional thermostat for controlling its heating function.
