LBSRTDESmoke S-bend

The S-bend deflects the duct system, for example where ducts cross. Trapeze corrugations stiffen the duct and reduce the risk of noise generation. Pre-wrapped 27 mm black insulation insulates the outside of the product.

Has joining profiles of 30 mm flange.

A specific relationship between the a-dimension, fall (f), and length (l) allows the LBSRTD3 to retain its cross-sectional area and avoid restricting airflow. Standard lengths and standard drops support this requirement.

The product is CE marked according to EN 12101-7 and used in a rectangular smoke control system – multi compartment (see Declaration of Performance).
