Engineered for robustness, Lindab Safe offers exceptional air tightness, which minimizes energy losses and ensures optimal air flow efficiency, contributing to significant energy savings and reduced operational costs. Its high-quality materials are resistant to corrosion, making it suitable for various environments where durability and reliability are paramount. Additionally, Lindab Safe's compliance with rigorous pressure classes ensures it can withstand demanding conditions, providing consistent and effective ventilation. These features make Lindab Safe a perfect solution for enhancing air quality, operational efficiency, and long-term sustainability in different applications.

Why Lindab Safe

  • Quick assembly.
  • Can be twisted and adjusted with tightness unaffected.
  • Installation without sealant or solvents.
  • Can be used in all environments.
  • Gasket remains tight from 5 000 Pa negative pressure to 3 000 Pa positive pressure.
  • Can withstand high pressure which are specified in the SR duct data sheet.
  • Eurovent certified to tightness class D.
  • Air tight systems gives energy savings
Our Safe gasket system is based on a U-shaped profile of solid rubber. The gasket is fixed with a steel band in a groove at the end of the fitting.
As standard are Safe-fittings always supplied with an EPDM (ethylene-propylene rubber) gasket. The material has been chosen due to its long service life and the best possible resistance to ozone and UV radiation. It is also highly tolerant to temperature variations. Under normal conditions, the gasket can withstand:
-30 °C to +100 °C continuous
-50 °C to +120 °C intermittent
As special for installations which demand high temperature tolerance and somewhat higher oil resistance, Safe fittings can be supplied with a special silicone rubber gasket. This gasket is recognized by its blue colour. Mastic sealed fittings for higher temperatures are also produced with a more temperature resistant mastic.
Temperature tolerance:
-70 °C to +150 °C continuous
-90 °C to +200 °C intermittent
When fittings are installed in ducts, the gasket lips will be bent backwards. This means that the gasket will be better at withstanding negative pressure than positive pressure, since the negative pressure will tend to press the lips harder against the duct walls. The following pressure differences must not be exceeded, to cope with tightness class D.
Positive pressure in duct 3000 Pa
Negative pressure in duct 5000 Pa
The European standards allow a greater tolerance range between the duct and matching fittings as the diameter increases. In order to achieve maximum air tightness for all dimensions, we have chosen to use successively bigger gaskets as duct dimensions increase.
