Oblong rigid spiral ducts: CSRO
The oblong duct is a galvanised steel duct, which is a high-performance alternative to rectangular ducting enabling high airflows in limited spaces (suspended ceiling), or with visible attachment in commercial and multi-occupancy residential buildings. The oblong duct is straight galvanised steel sheet, shaped into its L x H dimensions by forming and calibrating a circular duct on a hydraulic press.
The + products
- small size for high airflow,
- good airtight performance and controlled pressure losses,
- easy to install and maintain (no inaccessible corners).
- controlled pressure losses,
- standard dimensions.
- bar length: 3 m,
- ribbed tubes with smooth end pieces to ensure airtight seal on rigid connections,
- pressure loss in oblong duct = that of circular duct of equivalent diameter,
- standard dimensions.
- accessories easily slotted on: ducts are female, accessories are male,
- attached using perforated strips, rails, etc.
