Product Description

Perforated grilles (PPG) are suitable for extract air in either sidewall or ceiling applications. Grilles consist of a 50% free perforated sheet mounted in an aluminium frame.

Available options are Opposed Blade Damper (OB), Hinged Core (HC) and Core Only (CO), and Filter Frame. PPGG grille frames are manufactured from extruded aluminium sections, the mitred corners being fully welded and linished.

Standard finish is RAL9010 or polyester powder coated to the customers colour requirement.

PLENUM BOXES

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.
