Donaldson acquires Aerospace Filtration Systems

Donaldson Company Inc. announced March 1 that it has acquired 100 percent of the shares of Aerospace Filtration Systems Inc. from Westar Aerospace and Defense Group Inc. Terms of the acquisition were not disclosed.

AFS, based in St. Charles, Mo., is the industry leader in designing, developing and manufacturing high-performance air filters for commercial and military aircraft. AFS had annual sales of approximately $18 million in calendar year 2006.

"The acquisition of AFS compliments our existing aerospace filtration business well," said Lowell Schwab, senior vice president, Engine Systems and Parts. "Donaldson and AFS have already worked jointly over the last year to apply our media technology to AFS's military and commercial aircraft systems. The acquisition of AFS allows us to further combine our filtration and manufacturing capabilities with AFS's strong market position."
