Since the invention of the first air filter which is credited to Mr. Donaldson, the company has been a leader in the filtration industry. Many companies have even gone so far as to privately relabel the Donaldson product over trying to create their own. Donaldson's reach goes so far as to even having the majority of our military's vehicles using their filters. They have been an industry leader with their PowerCore air filters which have increased efficiency all while being substantially smaller then their traditional counter parts. Heavy-duty truck and off-road equipment manufacturers demand compact, high-performance air filtration solutions and Donaldson continues to deliver. PowerCore G2, the next generation of Donaldson PowerCore filtration technology, is designed with a 30 percent smaller footprint with the same straight-through airflow and high-density filtration system as the "original" PowerCore - hence Big Performance, Small Footprint.
