PMCF Advises Aero Filter in its Sale to Rensa Filtration

PMCF Investment Banking (“PMCF”) is pleased to announce that it served as the exclusive investment banker to Aero Filter, LLC (“Aero Filter” or the “Company”) in its sale to Rensa Filtration (“Rensa”), which was a portfolio company of Audax Private Equity (“Audax”) when the transaction closed, and has recently been acquired by AEA Investors (“AEA”) and British Columbia Investment Management Corporation (“BCI”).

Headquartered in Madison Heights, Michigan, Aero Filter is an established regional distributor of commercial and industrial air filtration products serving customers across a diverse range of end markets throughout Michigan and the surrounding region. In addition to its distribution capabilities, the Company provides value-added filtration services including air filter replacement services and has built a strong reputation for technical expertise and responsive customer service, leading to long-standing customer relationships.

Rensa is a leading designer, manufacturer and distributor of highly engineered, consumable air filtration solutions focused on helping protect people and systems in critical environments and applications. Aero Filter joins Rensa’s growing network of regional distributors, strengthening its ability to serve end users directly through local technical sales and service teams. That network is backed by Rensa’s vertically integrated model — from filter media design and production, to filter manufacturing, to regional distribution and on-site service.

Dave Polens, Chief Executive Officer of Aero Filter, and Chuck Dankanics, Chief Operating Officer, commented, “For decades, Aero Filter has built its reputation on technical expertise, exceptional service, and strong customer relationships. We believe Rensa is the right strategic partner to build on that foundation, creating new opportunities for our employees and customers while preserving the values that have defined our success. We appreciate the PMCF team for their unwavering support and trusted advice throughout the process.”

PMCF served as Aero Filter’s exclusive investment banker, managing the transaction process and advising the Company through closing. Joe Wagner, Managing Director of PMCF, added, “Aero Filter has built an outstanding reputation by pairing deep technical knowledge with a consistent commitment to its customers. Rensa is a strong strategic fit for the Company, and we believe the combination will create meaningful opportunities for Aero Filter’s employees and customers. It was a privilege to advise Dave, Chuck, and the Aero Filter team on this important transaction.”

The transaction closed in September 2026.
