Circular ductwork
SPIRO circular duct system corresponds tightness class D, based on a homogeneous EPDM rubber profile. The rubber gasket is placed at the bent end of the piece, thus being fixed in a fitting so the correct position of the gasket is ensured.
Thanks to a rubber gasket air losses are reduced and the necessary air flow is maintained, thus avoiding the oversizing of the entire ventilation system.
Installation of the SPIRO system is quick and easy, thanks to the gasketed joint system, no additional materials are needed to seal the system.
We produce SPIRO circular ducts in a diameter range between 100mm and 1250mm.
