AJR Filtration has added string wound, melt blown, and carbon wrapped filter cartridges, formerly from Delta Pure Filtration to our product offering. The expanded portfolio enhances AJR's position as a leading US manufacturer of high-quality engineered liquid and dust filtration products. All production and support operations continue under one roof in our West Chicago, IL filtration headquarters. Delta Pure part numbers will not change. We look forward to serving your liquid filtration needs with more quality filter options, greater economies, and the convenience and simplicity of a single customer account.
