Central collector 300x60mm for 2 rectangular connections 204x60mm and connection with the vertical duct with dia 150mm.

• Ventichape

• This special metal central collector with integrated air conductor is used for air flow rates up to 150m³/h. By means of a connection on the spiralled duct with dia150mm, there are two connections of 200x600mm, which split the main rectangular connection of 300x60mm at an angle of 45°. They are glued together on the inside to be sure that the air tightness is guaranteed. A connection piece MDF is needed for connection with the rectangular duct KTL-SD.

• Central collector made of KTL coated steel (5µm). Thanks to this KTL coating, the central collector is resistant to the corrosive elements of the cement screed (compression strength 80kg/cm²). The KTL coating is also dust and moisture repellent, which makes it very appropriate for ventilation applications.
