The type “variovent” is designed in compliance with the standards of cleanroom facilities. The adjustable panel allows air volume regulation as necessary. Three standard sizes for air volumes between 10 and 1,300 m³/h are available on stock. The installation depth of the ventilation grille is adapted to the situation on site and installed flush with the wall surface. The defined perforation allows a free cross section of 35 %. This way, the air performance of the ventilation grille can be increased compared to grilles with air choke. The compact design gives the grille very high stability and torsion resistance. Thanks to the frame the overflow grille is self-supporting and independent of the partition construction.
