DUO 222 Downlight
The DUO 222 Downlight is a next-generation lighting solution engineered for critical cleanroom environments. Combining high-efficiency LED illumination with integrated Far-UVC (222 nm) decontamination, this dual-function luminaire delivers both optimal lighting and continuous microbial control—seamlessly replacing standard cleanroom fixtures.
Safe, Continuous Decontamination—Even During Operation
As Far-UVC technology safety profile for occupied spaces, the DUO 222 Downlight enables around-the-clock disinfection without interrupting workflows. Seamlessly integrated into your facility, it operates silently in the background—no need to pause production or disrupt daily activities.
Dual Technology, One Fixture
As its name suggests, the DUO 222 Downlight merges two essential functions into one compact, ceiling-mounted unit:
- A central Far-UVC module provides continuous, chemical-free air and surface decontamination, proven effective against bacteria, viruses, and spores.
- Surrounding LED light (4000 K) delivers uniform, flicker-free illumination with a 120° beam angle, fully customizable to meet varying cleanroom lighting specifications.
- Customizable modes: Multiple operating modes including continuous, scheduled duty cycles and motion-activated decontamination for energy optimization. Transferring a UV-sensitive product or performing a process which is UV sensitive? Switch to only LED white illumination at any time and have the decontamination later.
Designed for Cleanrooms – Plug & Play Integration
Purpose-built for cleanrooms up to ISO Class 5 / Grade A-B, the DUO 222 Downlight is compatible across all critical areas—from CNC (Classified Non-Classified) spaces to any aseptic production zones. The fixture installs flushed to the ceiling, ensuring unobstructed airflow and preserving cleanroom integrity.
Designed as a plug-and-play upgrade, the DUO 222 Downlight can directly replace standard cleanroom luminaires without structural modifications. Whether you're retrofitting an existing cleanroom or outfitting a new one, our fixture fits standard ceiling grids and complies with cleanroom sealing requirements. Upgrade to dual-function lighting and disinfection—without downtime, construction, or re-certification delays.
Key Features
- Far-UVC Technology (222 nm): Provides safe, continuous microbial inactivation without harmful UV exposure risks or chemical residues.
- LED Illumination (4000 K): Delivers high-efficiency, flicker-free white light with adjustable lumen output for task-specific lighting levels.
- Programable modes: Independently control Far-UVC and LED lighting. Multiple operating modes including continuous, scheduled duty cycles and motion-activated decontamination for energy optimization.
- Active Dehumidification: Integrated solid-state dehumidifier prevents internal condensation and corrosion, extending service life.
- Primary Seal System: Designed for easy inspection and replacement every five years to ensure long-term sealing integrity.
- Seamless Ceiling Integration: Flush-mounted design supports various cleanroom ceiling systems while maintaining airflow and hygiene standards.
Ideal Applications
- Pharmaceutical and biotech manufacturing
- Semiconductor and microelectronics production
- Healthcare isolation and surgical suites
- High-containment laboratories and clean R&D environments
Maintenance-Friendly Design
The rear module can be accessed and removed via a simple screw-lock system, allowing fast, tool-assisted servicing with minimal disruption to cleanroom operations.
Choose the DUO 222 Downlight for advanced illumination and pathogen control in one integrated solution—delivering sterile performance, energy efficiency, and long-term operational reliability for the most demanding cleanroom environments.
