Lindab Safe: the first air conditioning system in the world with a Eurovent certification for class D airtightness.

Lindab Safe includes a complete range of circular ducting, fittings, silencers, tees, and other necessary components needed for a quality circular air handling distribution. The basis of the system is the connection with double-edged sealing made of EPDM rubber. This sealing allows for quick and easy installation of the system while ensuring its high air tightness class in ATC 2 (D) category. For a firm connection of fittings to ducts, often just snapping onto the prepared connecting notches is sufficient. The so-called Click function is basically possible with all products in the Safe range with diameters ranging from 80 mm to 315 mm. Lindab Safe and Lindab Safe Click also hold the Eurovent certificate guaranteeing strength and tightness class D according to certification criteria for circular metal air handling duct systems (DUCT-MC).

Eurovent as a confirmation of the highest airtightness requirements

The purpose of certification by the independent testing laboratory Eurovent is to create a common set of criteria for all relevant parameters that allow for the assessment of products by this system and ensure the continuous achievement of monitored parameters over time. In practice, this means that the inclusion of Lindab products into the certification system facilitates the work of designers and engineers, as they no longer have to conduct time-consuming detailed comparisons and investigations of performance parameters. Designers, estimators, and investors can design products with confidence that the technical data provided in the catalog is very accurate. Lindab products that are certified by a reputable testing laboratory have the Eurovent logo stated in their technical documentation.

Eurovent also controls the manufacturing process, from its sustainability to safety and working conditions in production. The validity of the certificate can be easily verified at any time on the laboratory's website: www.eurovent-certification.com

Not just airtightness, but also the appearance of air handling systems

The Lindab Safe system, along with quick installation without the need for additional sealing and fixing materials and tightness quality, also emphasizes the final appearance. The ducting can naturally blend in with the construction, as it does not contain visible sealing elements that disrupt the architectural character of the interior. The basis for all components is galvanized steel, which, in turn, guarantees cross-sectional stability, resistance to environmental influences, and mechanical damage. Customers can also choose an alternative design made of special metal materials.


Thanks to exceptional surface treatments, the system can also be used in environments with high hygiene requirements, such as clean rooms, hospitals, food and chemical operations. Lindab Safe is also applicable for cases of air transport containing, for example, flammable, radioactive, or otherwise hazardous substances. Lastly, the system is also suitable for the exhaust of air with increased concentrations of corrosive substances, including chlorine, hydrogen, or condensed saline solutions.
