Since 1927, Falls Filtration Technologies has manufactured air and liquid filtration products, building a distinctive history around oil bath filters and aerospace filtration. The Stow company pioneered an oil filter that achieved a perfect bearing test on aircraft engines, and one of its early Unimaze air-intake filters flew aboard the Spirit of St. Louis. Today, Falls designs filtration solutions for equipment ranging from engines and compressors to aircraft and locomotives, serving customers through distributors across the United States and Canada.
