Square diffusers with adjustable deflectors

The WT 100 square swirl diffusers are used in the service sector and hospital settings. They have radially arranged adjustable blades, which enable two types of airjets to be obtained: swirling on the inner or outer circumference or vertically. The intense swirling motion enables a high induction effect with reduced air throws, guaranteeing a low temperature gradient in the occupied zone.
They are particularly well-suited for use in VAV systems with airflow reductions by up to 50% of the projected value.

  • WT square swirl diffusers, used in the service sector and hospital settings, ceiling-mounted or on exposed ducts;
  • Made from a front panel into which a series of adjustable deflection blades are inserted;
  • The blades enable two types of air jets to be obtained: swirling on the inner or outer circumference or vertically. The intense swirling motion enables a high induction effect with reduced air throws, guaranteeing a low temperature gradient in the occupied zone;
  • Suitable for VAV systems with flow reduction by up to 50% of total flow;
  • Can also be used for air exhausting;
  • Made from steel, painted white in RAL 9010;
  • The adjustable deflectors are made from black nylon (white on request);
  • Supply plenum in anodised sheet steel, with perforated equalising plate, control damper and circular side (S) or top (T) connection, in versions with internal insulation (model BOX WT 101 SI or TI) or without insulation (model BOX WT 101 S or T);
  • Where present, internal insulation is Class 1 polyethylene, 6mm thick.
  • High induction with or without Coanda effect;
  • Horizontal or vertical airflow;
  • Temperature differential up to 12 K when cooling and 15 K when heating;
  • Suitable for both VAV and CAV systems;
  • Plenum box with circular openings with diameter from 125mm to 315mm.
