About Us

In 1990, Charles Ekstam began research that led to the development of the Fuel Preporator®. Three years later, the first commercial Fuel Preporator® unit was sold. Over the past 20+ years, Fuel Preporator® models have been developed 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, vapor and entrained air from diesel fuel to increase fuel economy, power and performance.

Fast-forward to present day and PureFlow Technologies has moved the production of all products to Shelbyville, IN under the management and direction of DieselRx™ and Shares, Inc. Our production and order fulfillment program is now housed in DieselRx™'s ISO Certified, 70,000 square foot facility and works in conjunction with PureFlow's research and development team. Together, these innovative product lines have expanded the capabilities of our company and will offer our customers a wide range of quality diesel products.

In late 2010, we launched a new Fuel Preporator® model for Class 8 trucks and a new Factory Replacement Raptor® Pump (FRRP) will be released in early 2011. We'd like to thank our loyal customers for your continued support over the years and we look forward to growing with you in the future.

Great Products, Great Cause!

AirDog® is part of Shares, Inc., a unique non/profit agency that provides job and life skills training for adults with developmental disabilities. The production of our AirDog® products incorporates these individuals. Through the processes required for manufacturing, kitting and packaging of automotive products, they learn life skills that they can use to organize their life and solve daily challenges. This helps them become more self-sufficient and involved in the community around them. Along with teaching them valuable work skills, the proceeds from our DieselRx™ products are funneled directly back into programs that serve the disabled community. We are a true non-profit agency, so buying from us helps others.
