Ventilation grilles are air terminal devices for the supply air and extract air of ventilation and air conditioning systems. They direct the supply air into the room. Ventilation grilles with adjustable blades allow for adapting the discharge direction to the local conditions. The result is a mixed flow ventilation in comfort zones and industrial zones, with good overall room ventilation. Due to induction, the airflow velocity of the supply air flow decreases with increasing distance from the ventilation grille. The distance at which the airflow velocity reaches a certain defined value, e.g.

0.35 m/s, is called throw distance. The supply air flow from wall grilles that are arranged close the ceiling achieves a greater throw distance than a comparable free jet (without ceiling influence), due to the ceiling effect. Single grilles, groups of grilles and linear run sections all achieve different throw distances. In cooling mode, it is necessary to consider the jet deflection towards the occupied zone, which increases as the supply air to room air temperature difference increases and the discharge velocity decreases. In heating mode, the supply air jet is deflected towards the ceiling. This has no negative effect on the airflow velocity in the occupied zone, but it may affect the overall ventilation of the room.

Nominal sizes	225 × 75 to 2025 × 525 mm
Minimum volume flow rate	11 – 1,111 l/s or 40 – 4,000 m³/h
Maximum volume flow rate, with LWA max. 40 dB(A) without attachments	53 - 3,056 l/s or 189 - 11,000 m³/h
Supply air temperature	-12 to +15 K
