| |  For the nation’s largest distributor of industrial ammonia products, Airgas’s entry in the DEF marketplace makes perfect sense. We’ve been supplying NOx reducing agents since the ‘80s, and now operate one of the country’s largest private fleets. So we know firsthand about keeping diesels on the road and complying with EPA mandates. We’ve invested aggressively in SCR technology ourselves, and we make the most of that commitment by using ultra-pure AiRx diesel exhaust fluid.
