KTL HY • Main collectors

Central collector 300 x 60 mm for 2 rectangular connections 204 x 60 mm and connection with the vertical duct with dia 150 mm

• Ventichape

• This special metal central collector with integrated air conductor is used for air flow rates up to 150 m³/h. By means of a connection on the spiralled duct with dia 150 mm, there are two connections of 200x600mm, which split the main rectangular connection of 300x60 mm 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 80 kg/cm²)

• The KTL coating is also dust and moisture repellent, which makes it very appropriate for ventilation applications
