Rectangular vertical bend 90°
- The vertical bend of 90° is mainly used to integrate rectangular ducts into a wall starting from the floor (or cement screed). It is also equipped with an air conductor to reduce the air resistance. Connection with other rectangular connection pieces is made with MDF connection pieces.
Rectangular vertical bend of 90° made of KTL coated steel (5µm). Thanks to this KTL coating, the bend 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.
