rectangularexteriorcommercial

For duct or wall mounting or installation in round tubes in the supply air and return air installations of cinemas, shopping centres, halls and underground car parks. The small mounting depth prevents air vortex formation on the front face, as a result of which air is applied evenly to the whole grille surface. The susceptibility of the grille to corrosion is greatly reduced by the absence of weld spots during manufacture. Fitted with integrated G 4 filter insert (dry filter mat). With hit-and-miss damper for setting the air flow rate. 100 - 2500 m³/h
