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 simplifies the volume flow rate balancing adjustment during 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.

Quick sizing
Specification text
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. Spigots are suitable for ducting according to EN 1506 or EN 13180. Sound power level of the air-regenerated noise measured according to EN ISO 5135.
