Aluminum line grille with 2 adjustable perforated panels – 2000 mm – RAL 9016 + insulated plenum with airflow control damper

Aluminium linear grille with 2 adjustable louvre blades – 2000 mm – RAL 9016 + insulated plenum with airflow control damper

The combination of the insulated plenum and aluminium linear grille with two adjustable louvre blades forms a complete set for silent, evenly distributed air supply in spaces where comfortable, draft-free air distribution is desired, such as offices, retail areas, meeting rooms, and hotel lobbies. 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 function as one unit: the plenum evenly distributes the supply air along the full slot length of 2000 mm, while the linear grille disperses the airflow uniformly through two adjustable deflector profiles. The dual-slot design enables higher airflow rates at low noise levels. Thanks to the Coanda effect, the air is guided along the ceiling without drafts, ensuring a comfortable indoor climate in the occupied zone.

Benefits and features

• Complete set including mounting accessories: The plenum and linear grille are engineered to work together and come supplied with the required mounting bracket and hex screws.
• Quiet operation through sound-absorbing insulation: The insulated plenum attenuates noise from the ductwork, minimising sound disturbance.
• Precisely adjustable airflow: The integrated airflow control damper allows fine tuning during the commissioning phase.
• Draft-free air distribution via Coanda effect: The linear grille directs the air along the ceiling, ventilating the occupied zone comfortably without direct air jets.
• Higher air capacity at low noise levels: Two parallel-operating deflector profiles enable increased airflow rates without noticeably raising sound levels.

Installation and applications

The linear grille is mounted from below onto the plenum using the supplied galvanised mounting bracket. For connection, the air intake deflector is rotated 90°, after which the grille is simply fixed from underneath 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 on the linear grille can be manually adjusted for horizontal or vertical airflow direction. This set is suitable for use in offices, shops, schools, restaurants, hotels, and other commercial buildings.
