What TES Clean Air Systems does

TES Clean Air Systems (legal entity: Technical Equipment Sales, Inc.) is a micro-contamination control sales representative and exclusive global distributor of Airflotek filtration products, founded in 1986 and headquartered at 41 East Airway Blvd., Livermore, California. The company designs, engineers, and supplies custom Fan Filter Units (FFUs) using HEPA, ULPA, and PTFE filter media for semiconductor process tools, Equipment Front End Modules (EFEM), pharmaceutical Restricted Access Barrier Systems (RABS), laminar flow transfer carts, nuclear HEPA installations, and Flat Panel Display (Gen 10+) environmental enclosures. Its differentiated technology portfolio includes the patent-pending Lumifilter LED-in-HEPA lighting system, the proprietary Accu-Volume fan sizing system that accounts for international voltage/Hz variations, Dual Zone ionization filters for tight-clearance wafer plane applications, AMC (Airborne Molecular Contamination) prefilter retrofit kits, and Automatic Pressure Control (PLC-based cascaded multi-zone) FFUs, with Simco-Ion ionization products integrated into designs. The standard MAC-10 product line serves cost-driven construction-grade applications.

The company operates a sales-led, direct B2B go-to-market targeting semiconductor OEMs, pharmaceutical manufacturers, biotech firms, and nuclear operators, with lead engagement handled by two named engineering staff (Jim Harris, Larry Ottesen, the former identified as Owner). Pricing is quote-based on Net 30 terms; custom orders require signed approval drawings before component procurement and are non-cancellable. Marketing is limited to a website with technical blog content (semiconductor industry forecasts, FFU technology) and ESTECH/IEST conference participation; no publicly disclosed pricing exists. Customer-facing proofs cited include air flow uniformity of +4.8%/-4.4% at 98 FPM on a standard 9-inch PTFE FFU and part-number reduction from dual-wavelength LED integration.

On January 8, 2026, TES-Clean Air Systems was acquired by Cleanova — a London-headquartered industrial filtration platform owned by private equity firm PX3 Partners — alongside Airflotek, representing Cleanova's 5th and 6th acquisitions since 2023. The two entities are being consolidated into a single business unit within a 19-brand platform employing approximately 1,600 people across 10 countries. Prior to acquisition, TES operated independently with 1-10 employees; the company has no disclosed revenue in the source data.
