Steel Fire Rated Louvered Face Diffuser with Square Neck (Flush Face)
The SHFR series of fire rated, square or rectangular diffusers are available in various sizes and discharge air patterns to meet engineering requirements for capacity and directional throw in addition to a variety of frame styles to meet architectural requirements of today’s ceilings. They feature a 1/4” horizontal lip on all sides of the louvered core, resulting in a tight horizontal discharge pattern at the ceiling and a higher discharge velocity at the face. This creates a high induction region just below the face of the diffuser, which improves room air mixing. Because this series has higher discharge face velocities, they are an excellent choice for variable air volume systems with above normal temperature differentials. At typical flow rates, isothermal throws of 18 to 30 feet make the SHFR series ideal for mounting centrally in many spaces with high load requirements while providing high mixing rates in the space.
