Function and effect
The aluminium bars with a width of 0,5 mm are arranged with a distance of respectively 13 mm, so that the comb size of 13x13x13 mm provides a free flow area of 92%. This way high air volumes can be moved at low pressure differences and sound power levels. Because of the large free flow area, the grille is also especially well suited for usage as a cover grille for a fire damper or with smoke extraction systems.
