48×12 AHCD -Adjustable Split Deflection High Capacity Drum Diffuser, Surface Mount, Aluminum

The High Capacity Drum Louvers (HCD) consist of extruded aluminum blades mounted inside a rotatable drum to produce long air throws with a high degree of directional control. The HCD provides long throws to supply air to spaces that cannot be served by ductwork and conventional outlets due to structural or architectural restrictions. This makes the HCD ideal for use in warehouses, factories, stadiums, or any large enclosed space.
