Functional description
Extract air valves extract air from rooms and lead it into the extract air part of the air conditioning system.
Type LVS disc valves have a valve disc that can be turned. This valve disc facilitates volume flow rate balancing for commissioning.
Nominal sizes | 100, 125, 160, 200 mm |
Minimum volume flow rate | 10 – 25 l/s or 36 – 90 m³/h |
Maximum volume flow rate | 25 – 50 l/s or 90 – 180 m³/h |
Quick sizing tables provide a good overview of the volume flow rates and corresponding sound power levels and differential pressures.

Circular disc valves as extract air devices, preferably for small rooms. For installation into walls and suspended ceilings.
Ready-to-install component which consists of a valve casing with cross bar, a valve disc with threaded spindle, and an installation subframe.
The valve disc can be turned for volume flow rate balancing. The valve setting can be fixed with a lock nut.
Spigot suitable for ducts to EN 1506 or EN 13180.
Sound power level of the air-regenerated noise measured according to EN ISO 5135.
