Air filtration manufacturer and distributor Rensa Filtration acquired IREMA-Filter and its U.S. subsidiary Aeolus Filter Corp. from PINOVA Capital. Terms were not disclosed.

IREMA was founded 50 years ago near Postbauer-Heng, Germany and is a supplier of filtration media and filter media pleating technologies. Based in Archdale, NC, Aeolus Filter provides filters using IREMA’s media and pleating technologies and has a strong market presence in critical data center and healthcare air filtration applications.

Brandon Ost, CEO and Founder of Rensa Filtration, noted, “the filtration market has long held the IREMA/Aeolus business and filter technology in high regard, and we look forward to supporting their continued technology development, increased manufacturing capacity and commercial growth.”

IREMA’s filter media process technology is a flexible platform capable of making both polymeric microfibers and nanofibers and combining them to make innovative filter media structures with multiple layers, gradient structures, and mixed micro and nanofiber structures.

Andreas Seeberger, CEO of the IREMA group added, “Rensa Filtration is the ideal partner for us. Their track record in mission-critical filtration applications and focus on innovative solutions is a great fit for IREMA’s core competencies and unique technologies.”

The acquisition marks the ninth acquisition for Aurora, IL-based Rensa since private equity Audax invested in it during 2022.

Terms of the deal were not disclosed.
