Steel Louvered Face Diffuser with Square or Rectangular Neck and High Induction Vanes (Flush Face)
The SHV series 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 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. Each successive louver has vanes mounted in opposite directions behind the blade, which direct the air in opposite directions. This causes the discharged air to become turbulent in the horizontal plane, thereby increasing the induction rate of room air and shortening throw. Because these diffusers have higher discharge face velocities and turbulent horizontal jets, they are an excellent choice for variable air volume systems with above normal temperature differentials. At typical flow rates, isothermal throws of 15 - 25 feet make the SHV ideal for mounting centrally in many spaces with high load requirements while providing high mixing rates in the space.
