Keltec was founded in 1982 by Ed. Kaiser, Sr., formerly and engineer of the Air Maze Corporation for over 20 years. With initial production of air-oil separators, Keltec eventually added air-intake filters, oil filters, coalescing filters and synthetic compressor lubricants.

Recently, Keltec acquired Technolab (a former division of Flair Corporation), another air-oil separator manufacturer making the new Keltec-Technolab the largest maufacturer 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.
