What Clean Rooms International does
Clean Rooms International, founded in 1982 and headquartered in Grand Rapids, Michigan, designs and manufactures engineered cleanroom components, air-handling equipment, and workstations for contamination-controlled environments. Its product portfolio spans SAM® Fan Filter Units (FFUs), the proprietary SAMLink Control System, terminal diffusers, modular hardwall and softwall cleanrooms, T-grid ceiling systems, HEPA-filtered lights and ceiling panels, pass-through cabinets, air showers, clean benches, tables, C-frame workstations, custom workstations, a battery-powered HEPA cart, and the Guardiair line of mobile air filtration units. Underlying technology centers on mechanical HEPA filtration, controlled airflow distribution, and integrated controls, with components engineered-to-order for facility-specific layouts.
The company operates a sales-led B2B model, selling engineered cleanroom systems and individual components to customers in medical/pharmaceutical, electronics/semiconductor, aerospace, research/education, food/cannabis/cosmetics, and commercial indoor-air-quality end-markets. It also offers NEBB-certified cleanroom testing, certification, and consulting services (certification achieved in 2019), creating a recurring service revenue stream alongside hardware sales. Leadership is long-tenured — CEO Timothy Werkema has led the firm since 1997 and COO Bret Asper joined the executive team in 2018 — and the company is privately held with 11-50 employees.
