AEA Investors and BCI Acquire Rensa Filtration

On October 8, 2026, AEA Investors' Middle Market Private Equity team (AEA MMPE) and the British Columbia Investment Management Corporation (BCI) revealed their acquisition of Rensa Filtration, a leading supplier of engineered air filtration solutions. This strategic move aims to further enhance Rensa's outreach and solidify its position across mission-critical industries, including data centers, power generation, and healthcare.

Founded in 2017 by Brandon Ost and based in Aurora, Illinois, Rensa has rapidly become one of the most prominent privately held filtration companies in the U.S. This acquisition marks a pivotal moment for Rensa, transitioning from an Audax Private Equity-managed entity to a collaboration backed by two major financial powerhouses. Audax continues to hold a minority stake in Rensa, signaling its ongoing confidence in the company’s strategic trajectory.
