What is the difference between the PRIST® Hi-Flash™ Hi-Flo™ vs. PRIST® Hi-Flash™ Lo-Flo™ additive aerosol products?
PRIST® Hi-Flash™ Hi-Flo Anti-Icing Aviation Fuel Additive is chemically identical in formula to PRIST® Hi-Flash™ Lo-Flo Anti-Icing Aviation Fuel Additive. Hi-Flo additive simply means the can delivers at a rate compatible with a 40 to 55 gallon per minute fuel nozzle rate while Lo-Flo additive cans deliver at a rate which is typical of AvGas or 15 to 30 gallon per minute. Lo-Flo additive is also used in helicopters which typically have to be fueled slowly. The PRIST® Hi-Flash™ anti-icing additive, DiEthylene Glycol Monomethyl Ether, is approved for addition to turbine fuel under ASTM specification D1655 and for aviation gasoline (AvGas) under specification D910. The additive is exactly the same for both turbine fuels and aviation gasoline. The additive itself is produced to ASTM specification D4171 and to the Military Spec MIL-DTL-8570B. The Lo-Flo additive product is no longer available.
