Our DEF starts with automotive-grade urea, sourced as a pure urea liquor and precision blended with high-purity water to achieve standardized concentrations. We never use evaporated solid “urea prill” that runs a risk of introducing ammonia, formaldehyde, or other contaminants, all of which can potentially damage your equipment.
To dispense fluid from a drum you may purchase a DEF pump from your local equipment supplier. Open drums require a non-micro matic hand pump. Closed micro matic drums may use a DEF compatible air or electric operated pump.
Air1 formulas are API certified, with the purity your vehicles need to perform at optimal efficiency. Additionally, they are nontoxic, stable, odorless, and colorless.
That’s because purity isn’t just the Air1 guarantee — it’s our obsession.
