Aluminum line grille with 4 adjustable perforated panels – 2000 mm – RAL 9016 + insulated plenum with airflow control damper

Aluminium Linear Grille with 4 Adjustable Deflector Blades – 2000 mm – RAL 9016 + Insulated Plenum with Airflow Control Damper

The combination of the insulated plenum and the aluminium linear grille with four adjustable deflector blades forms a complete set for quiet, even air supply in spaces where comfortable, draught-free air distribution is required, 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 matched and work as one unit: the plenum distributes the supply air evenly along the entire 2000 mm slot length, while the linear grille optimally directs the airflow across the room via four adjustable deflector profiles. 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 spreads smoothly 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 bridge and hex screws.
• Quiet operation through sound-absorbing insulation: The insulated plenum reduces noise from the ductwork, minimising sound disturbances.
• Precisely adjustable airflow: The integrated airflow control damper allows for accurate balancing 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 version in the range, suited for spaces with the highest ventilation requirements.

Installation and Applications

The linear grille is mounted from underneath onto the plenum using the supplied galvanised mounting bridge. For connection, the air inlet deflector is rotated 90°, after which the grille is easily attached from below onto the plenum. The plenum then connects to the ventilation duct via a round connection. Thanks to its compact height, the set fits in ceilings with limited free space. After installation, the deflectors of the linear grille can be manually adjusted to direct airflow horizontally or vertically. The set is suitable for offices, shops, schools, restaurants, hotels, and other commercial buildings.
