For quick fitting with smooth internal surfaces. The flange and bead provide excellent rigidity while a longitudinal laser joint ensures a total seal. As with the other parts which are manufactured using the same modular system, one unit can be joined to one another using easy, quick-fitting pull-ring one-part.

Their main characteristics include rapid fitting and perfect internal smoothness. The "MULTIFORM" system flange and bead at either end provide excellent rigidity and longitudinal length, ensuring perfect airtightness. High-quality finishing means top quality installations with excellent mechanical performance.

For general application in ventilation conducts, air-conditioning units and air expulsion mechanisms, especially suited for dust-collection tube networks and the pneumatic transport of materials and particles.
