SDT (SDTA / SDTB) Fan Swirl Diffusers

    • Product Details


      The SDT is the latest addition to the Waterloo range of fixed blade swirl diffusers and presents an attractive alternative to the existing range.

      These diffusers produce a horizontal radial air pattern with high induction effect, making them ideally suited for applications with high heating and cooling differentials.

      Manufactured from sheet steel with press formed blades, the units are available in four standard sizes with either 24 straight (SDTA) or 24 curved blades (SDTB).
