Lindab Safe is a complete range of circular ducts, fittings, silencers, t-pieces etc. The system is based on a double, factory-installed seal made of EPDM rubber. This seal makes the system quick and easy to mount. The system is type approved to tightness class D.

The product range covers a wide field of application within industry-, comfort- and residential ventilation. In special materials or coatings it can also be used in environments with extreme demands on hygiene, such as clean room-, hospital- and food and beverage industries.

In order to provide a complete offering of duct systems, Lindab also manufactures rectangular ventilation ducts and ventilation components. Many duct systems continue to be made up of rectangular parts and in certain countries these rectangular systems still dominate.

Within this area, Lindab offers three different systems. The Transfer system is a circular duct system using a band fastening for quick assembly and disassembly, which is mainly used for the transportation of light materials. The Isol system is a system with pre-insulated ducts and fittings with sheet steel inner and outer casings, intended for use both in and outdoors. The Marine system is an insulated system designed to achieve a particular fire classification and that has been especially produced for ventilation on vessels.

Lindab's premium brand for circular ventilation components is the Lindab Safe system. This is equipped with a double EPDM seal at the end of the ventilation components, secured in place by a metal strip in the manufacture. The seal is an essential detail since it allows airtight systems and thereby reduces leakage and results in high energy efficiency in the buildings. Lindab also supplies circular ventilation components under the Spiro brand, which also use a rubber seal.
