Washington-based Flanders Corp. is being bought by Japanese company Daikin in a $432 million deal.

The deal is expected to close by April.

This follows the 2012 purchase of Flanders Corp. by Insight Equity Holdings LLC for around $192 million, which President and Chief Financial Officer John Oakley described as “business as usual” in an interview at the time.

Flanders Corp. is one of the largest manufacturers of air filters in the United States, filters that are used for residential and commercial purposes. Founded in 1950, the company now has seven locations worldwide.

Daikin is the world’s leading commercial air conditioning manufacturer, and the acquisition of Flanders is expected to add a substantial boost to the company’s already growing market, pushing the projected sales up to $1.12 billion.
