The WORLD MARKETING OF AMERICA FA1000 is a replacement rotor kit designed for DuraHeat kerosene forced air heaters rated below 200,000 BTU/h. The kit includes a carbon rotor, four blades, and an insert — all the components needed to restore proper fuel atomization and combustion performance. Annual replacement of this rotor assembly is the standard maintenance interval recommended to keep the heater running at rated output and to prevent combustion inefficiency. Installation is a routine service task for HVAC techs and heating equipment service professionals familiar with kerosene forced air units.
This rotor kit is suited for residential and light-commercial temporary or supplemental heating applications where DuraHeat kerosene forced air heaters are deployed. It fits DuraHeat models operating below the 200,000 BTU/h threshold, making it a common annual maintenance item for job-site heaters, shop heaters, and portable forced air units running on kerosene fuel. The 0.5-inch rotor dimension is the critical fitment spec for this kit.
Fits all DuraHeat kerosene forced air heater models rated below 200,000 BTU/h.
Installation should be performed by a qualified heating technician or experienced service professional. Always shut off the heater completely and allow it to cool before disassembling the fuel or combustion components. Drain or isolate the fuel supply as required before removing the rotor assembly. Follow all applicable local codes and the manufacturer service documentation when reassembling the unit.
