BICBLFL Black Steel Weld-On Flange for Aspiration Systems (3 mm)
BLFL black steel weld-on flanges are designed for secure and durable connections of round ductwork in aspiration, dust extraction, and industrial ventilation systems. The flange is welded to the end of the duct and, together with bolted connections, provides a strong, stable, and long-lasting joint suitable for intensive industrial operation.
Manufactured from 3 mm thick black steel, the flanges offer excellent mechanical strength and resistance to mechanical loads. They are suitable for the installation of new aspiration systems as well as the expansion, modernization, or repair of existing systems.
