Diesel Equipment Inc specializes in Donaldson Filters and Donaldsons parts for diesel and gas powered trucks and equipment. One of the original Donaldson Filter providers since 1959, Diesel Equipment Inc has grown to be the largest stocking Donaldson distributors in the country. As Donaldson started to expand their lineup of products we started carrying more and more at our warehouse to better serve our customers. Now located in Seabrook, NH with a 7,000 square foot work space, we hold more product than anyone else in the US. Current owner Gregg Fowler has expanded the operation to new heights when he purchased it in 2007. We now ship all across the country and even deliver to our local customers if you can’t make it to us ! We intend to carry on this 60 year legacy and serve our customers in the best way possible.
