Aluminum line grille with 4 adjustable perforated panels – 1500 mm – RAL 9016 + insulated plenum with airflow control damper

Aluminium linear grille with 4 adjustable louvre blades – 1500 mm – RAL 9016 + 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 quiet, uniform 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 of extruded aluminium; the plenum is constructed from galvanised steel with sound-absorbing insulation. Both components are perfectly coordinated and function as a single unit: the plenum evenly distributes the supply air along the entire slot length of 1500 mm, while the linear grille optimally directs the airflow over the space through four adjustable deflector profiles. Equipped 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 disperses along the ceiling without causing draughts, ensuring a comfortable indoor climate in the occupied zone.

Benefits and features

• Complete set, including fixings: 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 attenuates noise from the duct, minimising sound disturbance.
• Precisely adjustable airflow: The integrated airflow control damper allows for fine adjustment during commissioning.
• Draught-free air distribution via 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 bracket. For connection, the air inlet deflector is rotated 90°, after which the grille is easily attached from below to the plenum. The plenum then connects to the ventilation duct via a round connection. Thanks to the compact construction height, the set also 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, shops, schools, restaurants, hotels, and other commercial buildings.
