TBD-FR - Fire Rated Plenum Slot Diffuser

The TBD-FR Fire Rated Plenum Slot Diffuser is a critical component for HVAC systems in construction projects requiring rigorous fire safety standards. Engineered to meet stringent UL time-temperature test criteria and NFPA 90A requirements, this diffuser provides peace of mind in fire-sensitive applications. Its robust construction utilizes steel and features a damper equipped with a fuse link for added safety. The TBD-FR is designed for versatility, suitable for use with hard or flex duct systems, as well as ductless applications, making it adaptable to diverse project needs.

One of the standout features of the TBD-FR Fire Rated Plenum Slot Diffuser is its aerodynamically curved blade design. This design promotes efficient air distribution by projecting a tight blanket of air across the ceiling, effectively minimizing drafts and ensuring consistent temperatures within the space. This blanking effect makes the TBD-FR particularly well-suited for variable air volume (VAV) operation, a common requirement in modern buildings. The diffuser is available in 3/4", 1", or 1 1/2" slot widths and 1 or 2 parallel slot configurations, offering flexibility in design and installation.

The TBD-FR Fire Rated Plenum Slot Diffuser is commonly specified for a wide range of construction projects, including commercial buildings, healthcare facilities, educational institutions, and other environments where fire safety is paramount. Its ability to integrate seamlessly with 3-hour or less fire-rated exposed grid, suspended ceiling systems makes it an ideal choice for architects, engineers, and contractors seeking reliable and code-compliant air distribution solutions.
