Adjustable Grilles Single Deflection and Double Deflection are suitable for supply and extract air for either sidewall or exposed duct applications. The single or double row of blades permit up to 45° deflection of the air, in either one or two planes.
ADG Grilles are manufactured from extruded aluminium sections, the mitred corners being fully welded and linished.
Also available as an Heavy Duty model. These are particularly suited to areas with a high degree of vulnerability or damage; typically car parks, school halls or industrial projects.
Standard finish is RAL9010 or polyester powder coated to the customers colour requirement.
Plenum boxes are accessories for use with Grilles and Diffusers. They are designed to equalise the pressure profile within the box and hence provide an even velocity at the face of the Grille or Diffuser without the use of Equalising Grids.
