    • Product Details


      The Waterloo Aircell WFO series floor diffuser offers the choice of horizontal or vertical air patterns with its flip over design, as well as a host of other unique & patented features.

      The WFOV low pressure vertical supply disc offers vertical projection with a 50% increase in air volume capacity, compared with standard WFOR units.

      The WFOI provides a high induction discharge pattern at between 30 and 45 degrees which provides dynamic mixing that results in efficient velocity equalisation within the occupied zone.

      The WFO diffuser discs are 200mm Ø and have been designed to resist permanent deformation when subjected to point loads up to 500 kg.

      The WFOV diffuser disc is suitable for point loads up to 300kg all materials used are fire retardant.
