AirDog By PureFlow

In 1990, Charles Ekstam, began research that led to the development of the Fuel Preporator®, the world’s first and only fuel air separation system for diesel engines with positive air separation. Three years later, the first commercial Fuel Preporator® unit was sold. 

In 2002, AirDog®, became the new Registered Trademark for the pick-up truck model Fuel Preporator®. Due to the popularity of the AirDog® Trademark, all Fuel Preporator® fuel air separation systems are now trademarked AirDog®. PureFlow® Technologies, Inc manufactured and marketed all AirDog® and Fuel Preporator® fuel air separation systems until 2009!

AirDog® fuel air separation systems, with the efforts of PureFlow AirDog®, have become the most sought after, after-market fuel system for diesel pickups, on the market today.
