Aluminum line grille with 1 adjustable perforated panel – 2000 mm – RAL 9010 + insulated plenum with airflow control damper

Aluminium linear grille with 1 adjustable pattern blade – 2000 mm – RAL 9010 + insulated plenum with airflow control damper

The combination of the insulated plenum and the aluminium linear grille with a single adjustable pattern blade forms a complete set for quiet, even air supply in spaces where comfortable and draught-free air distribution is desired, such as offices, retail stores, restaurants and hotels. The linear grille is made of extruded aluminium in RAL 9010; the plenum is constructed from galvanised steel with sound-absorbing insulation. Both components are coordinated and function as a single unit: the plenum distributes the supply air evenly across the full slot length of 2000 mm, while the grille precisely directs the airflow through the adjustable deflector profile. Thanks to the Coanda effect, the air spreads 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 fixing bracket and hex screws.
• Quiet operation due to sound-absorbing insulation: The insulated plenum dampens noise from the ductwork, minimising sound disturbance.
• Precisely adjustable airflow: The integrated airflow control damper enables 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.

Installation and applications

The linear grille is mounted from below onto the plenum using the included galvanised fixing bracket. For connection, the air inlet deflector is rotated 90°, after which the grille is simply fixed from underneath to the plenum. The plenum then connects to the ventilation duct via a round outlet. Thanks to the 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 for horizontal or vertical airflow direction. The set is suitable for use in offices, retail, schools, restaurants, hotels and other commercial buildings.
