Updated May 5, 2026

Donaldson Company, Inc., a global provider of technology-led filtration products and solutions, announced it has completed the acquisition of Filtration Group’s Facet Filtration business in a previously announced all-cash transaction valued at approximately $820 million. 

Facet offers fuel and fluid filtration solutions for mission-critical applications primarily in aerospace and defense as well as power generation. The company is said to be a pioneer in the jet fuel filtration market where its products are utilized at multiple stages of the supply chain from refinery to end fueling point.

Headquartered in Tulsa, Okla., Facet has 236 employees across the U.S. and Europe with key manufacturing locations in Oklahoma and Spain. Full-year 2025 sales were $108 million, primarily generated in North America and Europe at 57% and 26%, respectively.

According to Donaldson, the acquisition broadens Donaldson’s exposure to durable end markets including aerospace and defense and power generation; brings to the organization a large global installed base; and strengthens its aftermarket position, with approximately 70% of sales from consumables with regulated replacement cycles.

“Facet is a valuable, strategic addition to our Industrial Solutions business, increasing our exposure to attractive, durable end markets which require high-performance filtration solutions,” said Tod Carpenter, chairman, president and CEO, Donaldson Company, Inc. “This acquisition strengthens and diversifies our core product portfolio with new capabilities in fuel and fluid filtration including jet fuel filtration where Facet is a global pioneer.”

“Facet brings a highly complementary product portfolio with attractive margins and growth rates, enhancing our Industrial Solutions business,” said Rich Lewis, president and chief executive officer. “We are excited to welcome the Facet team to Donaldson Company.”
