AEA and BCI buy Rensa Filtration from Audax

AEA Investors' middle-market team and British Columbia Investment Management acquired Rensa Filtration, an Illinois-based maker of air filtration for data centers, power, semiconductor and healthcare uses, from Audax Private Equity. Audax and management keep minority stakes. Terms were not disclosed.

Why it matters: Data center and chip-fab demand is making mission-critical filtration a hot private equity buy-and-build play.
