SDFCH / SDICH / SDACH High Capacity Swirl Diffusers

    • Product Details


      The Waterloo SDFCH is a high capacity fixed blade swirl diffuser designed to produce a horizontal, radial air pattern with a turbulent, high entrainment jet characteristic and is ideally suited for applications with high heating or cooling differentials.

      The Waterloo SDICH is based on the SDFCH but allows the individual adjustment of blades to create a specifically required air pattern.

      The Waterloo SDACH is also based on the SDFCH but provides adjustment to the angle of all of the blades in unison in order to create the required air pattern. This can also be controlled remotely with an optional motor.

      Both the SDICH and the SDACH allow a continual adjustment from providing coanda effect to vertical dumping. They are particularly useful in areas that experience a varied thermal load, for example areas that are effected heavily by the changes in season.

      All products in the high capacity swirl diffuser range are suitable for ceilings up to 15m.
