The SAFG recessed grid LED troffer is a specification-grade luminaire engineered for the demanding conditions of ISO Class 4 cleanrooms and other sterile or controlled environments. Designed for recessed T-bar ceiling systems, this IP65-rated and IC-rated fixture delivers reliable, long-lasting performance in wet locations and insulated ceilings. Its rugged design and precision sealing make it ideal for use in pharmaceutical manufacturing, food processing, life sciences, healthcare facilities, and laboratory environments where cleanliness, safety, and durability are critical. The fixture is available in a 2x4 configuration and is fully certified for NSF/ANSI 2 Food Zone Non-Contact and Splash Zone applications, ensuring suitability for installations where sanitary compliance and washdown capabilities are required.
Built to perform under the strictest regulatory standards, the SAFG troffer is certified for hazardous locations including Class I Zone 2, Zone 22, Class I Division 2, Class II Division 2, and Class III. This makes it an excellent choice for facilities handling volatile substances, powders, or gases where explosion protection is essential. With certifications from CSA, UL, and ETL (C/US), and rated to IP65 and IP66 for dust and moisture resistance, the fixture provides dependable, contamination-free performance in the most challenging industrial and cleanroom conditions. It also meets ISO Class 4 and Class 5 cleanroom standards, ensuring compatibility with highly controlled environments.
Constructed from precision-formed, TIG-welded, one-piece 18-gauge cold rolled steel, the housing provides superior rigidity and corrosion resistance. Earthquake clips are provided to enhance safety and stability in seismic zones. The door frame is fabricated from 18-gauge cold rolled steel with a 60-degree beveled perimeter, TIG-welded corners, and self-centering locating studs for perfect alignment. It is secured with stainless steel aircraft cables and specialized military-grade captive fasteners featuring integral silicone O-rings that ensure lasting gasket compression and protection against overtightening. Custom extruded closed-cell silicone gaskets with vulcanized corners deliver continuous, redundant seals between the housing, door assembly, and plenum. This meticulous gasketing design prevents dust, moisture, or vapor infiltration, maintaining the integrity of the sterile ceiling plane.
The lens system incorporates a 0.125-inch thick high-impact acrylic diffuser with a smooth outer surface for easy cleaning and a diffuse inner layer that ensures uniform light distribution across the workspace. The lens is RTV silicone-sealed to the door frame, ensuring complete protection against contaminants while supporting frequent cleaning cycles common in sterile environments. Additional lens materials and optical options are available to suit specific project needs.
Internally, the fixture utilizes long-life LEDs paired with high-efficiency electronic drivers to deliver consistent, energy-efficient performance. With a rated life of over 50,000 hours (L80), the system ensures sustained output and color stability throughout its lifespan. The driver operates with low total harmonic distortion (<10%) and supports 0–10V dimming down to 1%, allowing precise control of light levels for comfort and energy management. All electrical components are CSA and UL approved, confirming compliance with North American safety and performance standards.
The SAFG troffer’s exterior is finished with a durable white polyester powder coat, providing a clean, corrosion-resistant surface suitable for sterile and wet conditions. With lumen output options ranging from 1,000 to 20,000 lumens and color temperature choices from 3000K to 5000K, it offers flexibility for a wide range of cleanroom, healthcare, and industrial applications. This luminaire combines superior sealing, robust construction, and efficient LED technology to deliver long-term reliability and hygienic performance across cleanroom, containment, and food-grade environments.
