Aluminum line grille with 1 adjustable perforated panel – 2000 mm – RAL 9005 + insulated plenum with airflow control damper

Aluminium linear grille with 1 adjustable pattern blade – 2000 mm – RAL 9005 + insulated plenum with air volume 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, uniform 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 from extruded aluminium in RAL 9005; the plenum is constructed from galvanised steel with sound-absorbing insulation. Both components are coordinated to function as a single unit: the plenum evenly distributes the supply air along the full slot length of 2000 mm, while the grille precisely directs the airflow via the adjustable deflector profile. Thanks to the Coanda effect, the air spreads along the ceiling without causing draughts, ensuring a comfortable indoor climate in the occupied zone.

Advantages and features

• Complete set including mounting accessories: The plenum and linear grille are designed to work together and come supplied with the necessary mounting bridge and hexagon screws.
• Quiet operation through sound-absorbing insulation: The insulated plenum reduces noise from the ductwork with minimal acoustic disturbance.
• Precisely adjustable airflow: The integrated air volume control damper allows for accurate balancing during the commissioning phase.
• Draught-free air distribution via Coanda effect: The linear grille directs 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 supplied galvanised mounting bridge. For connection, the air inlet deflector is rotated 90°, after which the grille can be easily attached from underneath to the plenum. The plenum then connects to the ventilation duct via a round connection. Thanks to the compact installation 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 stores, schools, restaurants, hotels and other commercial buildings.
