Aluminum line grille with 4 adjustable perforated panels – 1500 mm – RAL 9005 + insulated plenum with airflow control damper

Aluminium linear grille with 4 adjustable pattern blades – 1500 mm – RAL 9005 + insulated plenum with air volume control damper

The combination of the insulated plenum and aluminium linear grille with four adjustable pattern blades forms a complete set for quiet, even air supply in spaces where comfortable, draught-free air distribution is desired, such as large office buildings, shopping centres, auditoriums and other commercial projects with high ventilation demands. The linear grille is made from extruded aluminium in RAL 9005; the plenum is constructed from galvanised steel with sound-absorbing insulation. Both components are perfectly matched and function as a single unit: the plenum distributes the supply air evenly over the full slot length of 1500 mm, while the linear grille optimally disperses the airflow via four adjustable deflector profiles throughout the room. Featuring four slots, this grille combines the highest capacity in the range with the draught-free air distribution characteristic of the Econox system. Thanks to the Coanda effect, the air follows the ceiling without drafts, creating a comfortable indoor climate in the occupied zone.

Benefits and features

• Complete set, including mounting accessories: The plenum and linear grille are designed to work together and are supplied with the necessary mounting bridge and Allen screws.
• Silent operation thanks to sound-absorbing insulation: The insulated plenum dampens noise from the ductwork, ensuring minimal sound disturbance.
• Precisely adjustable airflow: The integrated air volume control damper enables accurate adjustment during commissioning.
• Draught-free air distribution via the Coanda effect: The linear grille directs air along the ceiling, ventilating the occupied zone comfortably without direct air jets.
• Maximum ventilation capacity: With four profiles, this linear grille is the most powerful model in the range, suitable for spaces with the highest ventilation requirements.

Installation and applications

The linear grille is mounted from below onto the plenum using the supplied galvanised mounting bridge. For connection, the air inlet deflector is rotated 90°, after which the grille is simply fixed from below onto the plenum. The plenum then connects to the ventilation duct via a round connection. Thanks to its compact build height, the set also fits into ceilings with limited free space. After installation, the deflectors of the linear grille can be manually adjusted to provide a horizontal or vertical airflow direction. This set is suitable for offices, retail spaces, schools, restaurants, hotels and other commercial buildings.
