Prist HI-FLASH HI-FLO Anti-Icing Aviation Fuel Additive - MIL-DTL-85470 |
Prist Hi-Flash Hi-Flo Anti-Icing Fuel Additive is less toxic, less volatile and easier to use than conventional additives. It controls icing in aircraft fuel by depressing the freezing point of water, reducing the occurrence of suspended ice crystals and ensuring that fuel will flow freely through lines and filters. Prist Hi-Flash additive is recommended for every refueling at a dosage rate of .10% minimum to .15% maximum by volume. Hi-Flo delivers the product at a rate compatible with a 40 to 55 gal. per minute fuel nozzle rate. When dissolved water separates from the fuel, some amount of Prist Hi-Flash additive quickly leaves the fuel and preferentially dissolves in the water. This depresses the water's freezing point. As the fuel gets colder, and more water particles appear, more Prist Hi-Flash additive leaves the fuel and enters the water, and your aircraft's fuel lines stay clear. Prist Hi-Flash anti-icing aviation fuel additive is authorized by the United States Armed Forces under Military Specification Mil-DTL-85470(B), and by the ASTM under Standard D4171 for use in civilian jet fuels as a fuel system icing inhibitor. As part of its ASTM approval process, the formulation of Prist Hi-Flash additive was reviewed and approved by turbine engine and turbine aircraft airframe manufacturers worldwide. |
