Aluminum line grille with 4 adjustable perforated panels – 1000 mm – RAL 9005 + insulated plenum with airflow control damper

Aluminium linear grille with 4 adjustable louvre blades – 1000 mm – RAL 9005 + insulated plenum with airflow control damper

The combination of the insulated plenum and the aluminium linear grille with four adjustable louvre blades forms a complete set for silent, uniform air supply in spaces where comfortable and 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 of extruded aluminium in RAL 9005; the plenum is made of galvanised steel with sound-absorbing insulation. Both components are perfectly matched and function as one unit: the plenum evenly distributes supply air along the entire 1000 mm slot length, while the linear grille optimally directs the airflow through four adjustable deflector profiles to the room. With four slots, this linear 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 flows along the ceiling without draughts, ensuring 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 bracket and Allen screws.
• Quiet operation due to sound-absorbing insulation: The insulated plenum reduces noise from the duct and minimises sound disturbance.
• Precisely adjustable airflow: The integrated airflow control damper allows accurate balancing during commissioning.
• Draught-free air distribution via Coanda effect: The linear grille directs the air along the ceiling, ventilating the occupied zone comfortably without direct air jets.
• Maximum ventilation capacity: With four slots, this linear grille is the most powerful version 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 bracket. For connection, the air inlet deflector is rotated 90°, after which the grille is easily fixed from underneath to the plenum. The plenum then connects to the ventilation duct via a round connection. Thanks to its compact height, the set fits into ceilings with limited free space. After installation, the deflectors of the linear grille can be manually adjusted for horizontal or vertical airflow direction. The set is suitable for offices, retail spaces, schools, restaurants, hotels and other commercial buildings.
