KWO – it is a 3m O-ring ventilation channel consisting of three extraction gratings accompanied by valves, of a one-sided end-cap and a regulatory valve from the installation grid side.
Optimal suspension height: 3-6 m above the shop floor level. KWO is connected to the ventilation grid with a T-connector, saddle T-connector or a saddle-shape cover. A flexible cable may be used to accurately position the KWO.
The distribution and distance between KWOs depend on the area and density of pollutants.
