Given the high costs of air treatment and a boom in the HVAC sector, ventilation systems must satisfy very stringent requirements. As a result, it is essential to ensure that duct connections are sufficiently leak-proof to keep the costs of operation at economically viable levels. To tackle this problem successfully, ALNOR Systemy Wentylacji Sp. z o.o. has developed a new end-to-end SPIRAL®system.

The SPIRAL®system is a proven system of quick-coupled spiral ducts and fittings provided with factory-installed EPDM gaskets. The gaskets provide leak-proof and durable joints between SPIRAL®system components. The system components are available in a full range of diameters from Ø80 to Ø1250 mm. SPIRAL system meets the requirements of PN-EN 12237 for air tightness class D (Certificate no. 0103/07).

The high-quality of workmanship and factory-installed rubber gaskets enable easy and quick assembly of ventilation ductwork. Ductwork based on SPIRAL®system components guarantees long and leak-proof service life and requires no additional sealants.

Application advantages

  • Quick and easy installation.
  • The gaskets are factory-installed without play to ensure their proper seating when connections are made.
  • This allows accurate mounting of fittings without the risk of breaching the seal or air leaks.
  • An environment-friendly Installation method which requires no silicones containing toxic solvents that could evaporate into the ductwork.
  • The system can be installed in all weather conditions.
  • Temperature resistance: -30˚ to +100˚C.
  • Maximum operating vacuum: up to 3000 Pa.
  • Maximum operating pressure: up to 5000 Pa.
  • Internal and external manufacturing control.
  • An aesthetic finish which is particularly important for exposed systems.
