Description

The AirDog FHK-1000 is a self-regulating Positive Temperature Coefficient (PTC) heater kit designed to prevent diesel fuel gelling in cold climates. It features a 300W Fleetguard heater element and is compatible with AirDog FPII-150 and FPII-200 4G fuel air separation systems that use the WS200-WD water separator. This heater adds heat to your fuel system and adjusts power based on temperature, requiring no additional thermostat.
