Atmus Filtration, the Nashville-based filtration company, is putting real money behind its push into industrial and indoor-air markets, spelling out terms of its roughly $450 million purchase of Koch Filter Corporation, the Louisville air-filtration maker. As part of the deal, Atmus says Koch will keep its brand and its Louisville operations in place inside a newly created Industrial Solutions business. The acquisition, which closed earlier this year, is part of Atmus’ effort to add more commercial HVAC, data-center and power-generation customers to its product mix.
As reported by Louisville Business First, Atmus paid about $450 million in cash for Koch Filter and confirmed that the Louisville operations will remain in place. In a Jan. 7 press release, Atmus Filtration Technologies said the acquisition closed on that date and quoted CEO Steph Disher: “We are excited to welcome the Koch Filter team to Atmus.” The company described the purchase as establishing its Industrial Solutions segment and expanding its indoor-air capabilities.
Koch's Louisville Footprint Will Stay
Koch Filter, founded in 1966, is headquartered in Louisville and lists manufacturing and distribution sites across the U.S., including East Greenville, Pa.; Houston; and Mira Loma, Calif., on its site. Koch Filter shows its main office at 8401 Air Commerce Drive in Louisville. Truelink Capital, which had owned Koch as part of Air Distribution Technologies, confirmed the sale in a press release when the transaction closed. Truelink Capital/PR Newswire framed the deal as a divestiture that positions Koch to grow under Atmus. OSHA inspection records include an entry listed as "Inspection: 303159040 - Koch Filter Corporation" with inspection type noted as "Planned" and scope "Complete," and show a closed inspection listed as "Inspection: 1144167.015 - 56979 - Koch Filter Corporation," which lists a site address as 56979 625 W Hill Street, Louisville, KY 40203 (Occupational Safety and Health Administration, U.S. Department of Labor). City records accessible via the Jefferson County PVA online property search can be used to confirm parcel ownership, assessed value, and other property details for 8401 Air Commerce Drive (Jefferson County Property Valuation Administrator).
Financing And Integration
To help fund the purchase, Atmus amended its credit facilities, entering an amended credit agreement that provides a $1.0 billion term loan and a $500 million revolving credit facility, according to the company’s SEC filings. The company said the deal was financed with a mix of cash on hand and borrowings under that facility, and it excluded acquisition-related and one-time integration costs from its adjusted results in the quarter. The SEC filings and Atmus's Q1 results provide the financing and cost details, including that $6 million of acquisition costs and $1 million of integration costs were excluded from adjusted free cash flow. The Q1 report also shows the company is reporting Koch Filter results inside the newly created Industrial Solutions segment.
Why The Move Matters For The Air-Filter Market
Analysts and market research point to steady growth in HVAC and industrial air-filtration markets, driven by tighter indoor-air-quality standards and rising demand from data centers and cleanroom manufacturing. That backdrop helps explain the strategic logic of the deal: adding Koch’s HEPA and high-efficiency product lines gives Atmus a broader portfolio to sell into commercial and industrial end markets. MarketsandMarkets/PR Newswire and other industry reports show the high-efficiency filter segments growing in those end markets. The Lawrence Berkeley National Laboratory's "2024 United States Data Center Energy Usage Report" documents the growing energy footprint of U.S. data centers, a trend that helps explain rising demand for cooling and filtration solutions (Lawrence Berkeley National Laboratory).
For Louisville customers and workers, the immediate takeaway is continuity: Koch’s brand and plants will remain as part of Atmus’s Industrial Solutions team even as the parent company lines up products and sales channels across a larger footprint. Investors and industry watchers will be watching upcoming earnings and integration milestones to see whether Atmus delivers the margin lift and growth it has forecasted. Investing.com noted that analysts will be tracking those integration effects in the near term.
