Ann Arbor, Mich.-based Kaydon Corp., a designer and manufacturer of custom-engineered parts for industrial, defense and medical equipment, announced recently that it has acquired all outstanding capital stock of Doraville-based Purafil Inc. for some $43 million.

Established in 1973, Purafil is a leading manufacturer and distributor of gas-phase air filtration systems that control odor and remove toxic gas releases, prevent corrosion of electronic equipment and preserve artifacts in archives, libraries and museums.

The company is supported by a global network of manufacturers’ representatives and sells its systems to customers in more than 50 countries.

“Purafil’s most well-publicized activities typically relate to the museum preservation field, including museums, libraries and archives,” Meredith Christiansen, a spokesperson for the company, told GlobalAtlanta.

Most recently, the company has been engaged in the preservation of the Dead Sea Scolls at the Museum of the Shrine in West Jerusalem. In the United States, it has been contracted by 25 museums including the U.S. Library of Congress and the Smithsonian Institution. It also has worked with nine libraries and and six archives in the U.S.

Internationally it has worked with 35 museums, including the Sistine Chapel at the Vatican; the Mohamed Mahmoud Khalil Museum in Giza, Egypt; the National Museum in Taipei, Taiwan; the Royal Castle in Stockholm, Sweden, The Hermitage in St. Petersburg, Russia and the Tower of London Jewel House in London. In addition, it has worked with more than 20 libraries and archives including the General State Archives in Utrecht, Netherlands.

“Purafil’s global market presence and leading product development efforts provide a strong foundation for its future growth,” said Kaydon’s president and CEO, Brian P. Campbell.

As is consistent with Kaydon’s de-centralized operating environment, Purafil will continue to operate as an independent, free-standing business unit, said a Purafil statement.

Kaydon distributes its products in Asia, Europe and North America.
