Commercial/Industrial Drum Louver for Spiral Duct Mount - Model RL-SP

The RL-SP drum louver allows for delivery of a jet or diffused air pattern in spiral duct installation. They are fully adjustable in both horizontal (through vane deflectors) and vertically (through the rotating drum) to provide primary supply air where needed in commercial and industrial applications.

  • Can adjusted horizontally to provide a straight flow primary jet for long throws (at 0° deflection) or a diffused pattern of primary air for short throws with greater spread (at 15° and 30° deflections).
  • Cylindrical drum allows primary air to be directed vertically within a 60° arc.
  • Dual Flow configuration available allows for dividing supply air flow through adjustable vanes (RL-SP-DF)
  • Available up to 48" long and is for use on 12" through 48" spiral pipe.
