Acoustic Air Transfer Grilles Description
For air transfer applications, the channel section core with integral noise absorption material provides an effective solution when transfer ventilation is required but noise transmission through the grille needs to be reduced.
Construction
From extruded aluminium sections with Pyrosorb acoustic infill to all blades. Screw holes in the flanges are provided as standard as there is no access through the grille to facilitate secret fixing.
Size and Weight
From 150 x 150 to 900 x 600. Single bank grilles type ATG00 will suit door or wall thicknesses from 44mm to 55mm. Double bank grilles type ATG20 will suit wall thicknesses above 110mm. For wall thicknesses between 55mm and 110mm, specify the ATG30 type.

Computer Room Floor Grilles Description
For supply or extract applications, the grilles are designed to integrate with the most popular raised access floor systems. Available in both Light and Extra Heavy duty grades to BS-EN 13264:2001.
Construction
Manufactured from heavy gauge aluminium extrusions, the frames are of fully welded construction. Extra heavy duty versions incorporate rear reinforcement mullions to maintain full structural integrity. The grille core is constructed from extruded aluminium bars with a face thickness of 6mm, and is welded into the retaining frame. The frame profile is designed to sit directly in contact with the floor pedestal earth terminal, removing the need for additional earth bonding connections and their associated expense.
Certification
Independently tested by the University of Salford, the R77 exceeds the requirements of BS-EN 13264:2001 for extra heavy duty applications.
Size and Weight
600 x 600 tile module size as standard, though other sizes are available on request. Light duty grille 8.5 kg Extra heavy duty grille 14.0kg Optional OBD 2.0kg
