aluminum ventilation grill / rectangular
NOVA-E is a rectangular aluminium grille with a large free area (up to 90%). It is adequate for usage in such premises that require a higher emphasis on appearance and is designed for air supply and air extract. For a balanced distribution of air through the entire grille it is recommended to use a damper or a plenum box.
NOVA-R1, -R2, -R3, -R4 - dampers
NOVA-UR - mounting frame
The NOVA-E grille can be mounted directly onto a duct using countersunk screws (type "1" mounting), or onto a wall using a mounting frame and spring clips (type "2" mounting).
NOTE: for mounting type "1" it is recommended to reduce the cut-out height dimension "H" by 10mm. This helps fixing the grille in proper position.
The NOVA-E grille is manufactured from aluminium profiles with eloxal coating or, if appropriate, a powderlacquered (RAL 9010 - white) surface finish; other RAL types are available upon request. The inside of NOVA-E is formed by a grating (with the openings’ dimensions being 12.7 × 12.7 mm), manufactured from an aluminium sheet with either no surface finish or a powder-lacquered surface finish.
