Throw is based on terminal velocities of 0.5 m/s - 0.25 m/s respectively. NC value is based on a room absorption of 10 dB, re 10-12watts.

Dash (-) in space indicates NC value less than 20. With G1 damper, the pressure loss is 1.136P, and add 2 for NC value.

RA/RAC Bar Grille

Linear Bar Grille (RA)

Curve Type Linear Bar Grille (RAC)


Materials RA-A Extruded aluminium A6063.

Features The bar grille air blades are fixed & not adjustable. Maximum single length is

2700m. Above this length, the grille will come in multiple section. The neck sizes (w) are proportional to the number of linear bar blades. Please refer to the following table. Two different types of linear bar face deflection angle are available. The bar grilles that come with plenum boxes are known as RAB. Approximately 65% free area.

Surface Finish Baked white powder coat or natural anodized as standard.

The curved structure and aesthetic appearance of RAC make it perfect to beinstalled at the round column or curved wall.
