About Us

October, 2009, W.A.P. of Shelbyville, Indiana, entered into a Patent License Agreement with CD Patents, LLC. and a Manufacturing/Sales Agreement with PureFlow® Technologies, Inc. to Advertise, Manufacture, and Market the “AirDog®” Fuel Preporator® fuel air separation systems for the Pick-up Truck Market for the United States and Canada. Raptor® fuel pumps, as well as the use of the Registered Trademarks AirDog®, Fuel Preporator®, Raptor®, and PureFlow®, are also included in the Agreements.

The company, “PureFlow AirDog®” was created by W.A.P. to handle the marketing, manufacturing, and sales of the AirDog® and Raptor® product line for pickup trucks. PureFlow® Technologies continues to develop, manufacture and market AirDog® Fuel Preporator® products for all other diesel engine applications.

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. During the following 20+ years, PureFlow® Technologies, Jefferson City, MO, has developed Fuel Preporator® and AirDog® models for virtually every diesel engine application including commercial trucking, pick-up trucks, military, marine, agriculture and mining. This high output pump and filtration system designed specifically for diesel engines is the most effective technology to remove water, particulates, and most importantly entrained air & vapor from diesel fuel to increase fuel economy, power and performance. 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. Under the management and direction of DieselRx® and Shares, Inc., PureFlow AirDog’s production and order fulfillment program is housed in DieselRx®'s ISO Certified, 70,000 square foot facility in Shelbyville, Indiana. Together, these innovative product lines have expanded the capabilities of the company and will offer our customers a wide range of quality diesel products.
