Who We Are
US-DEF is a new name owned by well-established fleet products and services company Ayr Data, Inc. (ADI). ADI was founded in June 2009 by Mr. Gary Davidson and Ms. Lore Devra Levin. Clean Ayr is the “registered trade name” and “doing business as” for ADI. Clean Ayr was instrumental in providing bulk DEF and fuel additives to the fleets operated by the North Texas independent school districts and their related municipalities. Clean Ayr also supports key public and private fleet operations across the territory. US-DEF’s experienced and talented executives have decades of combined experience in transportation, fleet management, and DEF.
What We Do
We have been delivering bulk DEF since 2015 to commercial customers, independent school districts and municipalities. We also support major customers with bulk DEF delivery in the greater Dallas/Fort Worth area. In 2024, we released US-DEF to the retail market in 2.5-gallon jugs.
