Cleanova Acquires SV Techsol, Expanding Its Semiconductor and Ultra-Clean Controlled Environment Filtration Capabilities
Cleanova, a leading global manufacturer of advanced industrial filtration solutions owned by PX3 Partners, the London-headquartered private equity firm, announces today the strategic acquisition of SV Techsol, Inc. (“SV Techsol” or the “Company”). Founded in 1990 by John Dryden and headquartered in Campbell, California, in the heart of Silicon Valley, SV Techsol designs and manufactures highly engineered, customized fan filter units (“FFUs”) and tool-integrated environmental control modules for advanced semiconductor equipment manufacturers, including systems for wafer fabrication, metrology, and inspection.
The addition of SV Techsol further expands Cleanova’s presence in semiconductor and ultra-clean controlled environment filtration, following the acquisitions of TES-Clean Air Systems (“TES”) and Airflotek in December 2025. Together, the three businesses form a core part of Cleanova.NEXUS™, Cleanova’s platform for semiconductor, cleanroom, data center, and other highly controlled environments.
SV Techsol brings deep, differentiated engineering capability to mission-critical semiconductor applications, an industry experiencing rapid growth through investment in AI infrastructure. Its products include customized temperature-controlled FFUs, ionization and electrostatic discharge systems, and chemical filter systems for airborne molecular contamination control environments. These products are specified into customers’ qualified tool platforms and inspection systems, where precise particle, thermal, chemical, and vibration controls are critical to semiconductor manufacturing. SV Techsol will continue to operate under its brand name.
Chris Cummins, President and Chief Executive Officer of Cleanova, remarked: “SV Techsol is an exceptional business and outstanding strategic fit for Cleanova. For over thirty years, John Dryden and his team have built highly engineered, customized solutions that the world’s leading semiconductor equipment manufacturers design into their tools. Bringing together SV Techsol, TES, and Airflotek offers customers deep design, engineering, manufacturing, supply chain, and aftermarket service capabilities across the semiconductor filtration value chain. This means greater capacity, engineering depth, and responsiveness. We are proud to welcome the SV Techsol team to Cleanova.”
John Dryden, Founder and President of SV Techsol, commented: “I started this company in 1990 with a simple belief: engineer it right, never let the customer down, and the work will follow. That is exactly what our team has done for over 30 years. In Cleanova, I found a partner that understands what we do and that shares our commitment to technical excellence and customer service. This is the right home for our people and the right next chapter for our customers. With Cleanova’s resources, global reach, and manufacturing capabilities, this team will grow and innovate in ways that we could not achieve alone. I could not be more excited about what comes next.”
The Managing Partners of PX3 commented: “We are delighted to support Chris Cummins and the Cleanova management team in this acquisition. SV Techsol is a high-quality, engineering-led business that bolsters Cleanova’s position in an attractive segment of industrial filtration. This investment reinforces our commitment to Cleanova’s continued growth.”
Cleanova enlisted the support of Alvarez & Marsal as accounting advisor; Ashurst Perkins Coie as legal advisor; BDO as tax and structuring advisor; and Marsh as insurance advisor.
