Spiral Round Duct System

SPIROFLO

“SPIROFLO” Spiral Duct System is manufactured to meet the most stringent specifications and quality standards using our vast experience and expertise in the field. This system is available in our range of products for various applications. Energy efficiency, indoor air quality and fine workmanship are the basis of our engineered products.

“SPIROFLO” Spiral Duct System is produced on original Spiro ‘Tubeformer’, Spiro ‘Gore Locker’ and Spiro ‘Stitch Welder’ machinery’s from ‘SPIRO INTERNATIONAL S.A’., Switzerland.

The “SPIROFLO” System is made on from sheet metal consisting of lockseamed round spiral tubes with an extra deformation on lock in the seam (The ‘Bubblan’ patent).

SPIRO

SPIRO INTERNATIONAL S.A. has developed its complete range of quick-fitting, spiral-seam ducts and fittings with factory-fitted sealing gaskets of EPDM rubber. The sealing gasket provides a tight and reliable joints. The system complies to DW 144 Class ‘C’[Eurovent 2.2=IV (DIN 24194)] specification. SPIRO system is leakproof when fitted and does not require any additional sealing.

The SPIRO sealing system is based on a profile of homogeneous EPDM rubber. The rubber gasket is located in a groove at the end of the fitting and is securely attached by means of an return edge. This design ensures that the rubber gasket is always held in its correct position.
