KELTEC Technolab was founded in 1982 by Ed Kaiser, Sr., formerly an engineer of the Air Maze Corporation for over 20 years. With initial production of air-oil separators, KELTEC Technolab eventually added air-intake filters, oil filters, coalescing filters and synthetic compressor lubricants. KELTEC acquired Technolab (a former division of Flair Corporation), another air-oil separator manufacturer making the new KELTEC Technolab the largest manufacturer and supplier of air-oil separators in North America.

Today, KELTEC Technolab provides their products as original equipment to most of the major manufacturers of air compressors in North America.
