Lindab SLU 100 Circular Silencers
Eurovent certification
Lindab’s circular duct system with rubber gasket connections Lindab Safe and
Lindab Safe Click is certified to strength and leakage in tightness class D
according to the Eurovent Certified Performance program for circular metallic
ducts systems (DUCT-MC 17.11.002).
Lindab products that are Eurovent certified have the Eurovent logotype in the
footer of the technical documentation. Note: Most Lindab Safe and Lindab Safe
Click and the most commonly used product in a ventilation system are essen-
tially better than class D, however some products are according to EN 15727
not class D as a single product. These prod-ucts are stated in the
documentation as Class C and can be used in D class systems to a limited
extension.
Important!
In order to fulfil the requirements for air tightness class D, the silencers must be installed according to these instructions.
Installation
To achieve the certified tightness class for these products they should be
installed in accordance with our assembly instructions for Lindab Safe Air
Duct System.
Mounting
Examples for mounting of the silencers with circular connections. Support
elements type and quantity should be selected according to local regulations
and silencer weight to ensure system integrity. 
Fire insulation of silencer
The silencer should have the same thickness of insulation as the rest of the duct system.
Maintenance
The silencers normally don’t require any maintenance. If nessessary, the silencer can be cleaned with a soft nylon brush or vacuum cleaner.
Cleaning of round shaped and low built silencers
Open the nearby access door and clean with a soft nylon brush. If the silencer
is equipped with centre splitter or pod, both sides needs to be cleaned.
Cleaning of openabe silencers
- Loosen the screws.
- Be careful not to drop the access door.
- If the attenuator is equipped with centre splitter, loosen the screws. Hold the splitter to prevent it from falling down.
- Clean the attenuator with a soft nylon brush or vacuum cleaner.
- The attenuation material is removable for better cleaning or changing. (If you want to change the material, please contact Lindab Sales).
- When the attenuator is cleaned, place the attenu-ation material and the splitter back on it’s original place.
- Place the access door and tighten the screws.
At Lindab, good thinking is a philosophy that guides us in everything we do.
We have made it our mission to create a healthy indoor climate – and to
simplify the construction of sustainable buildings. We do that by designing
innovative products and solutions that are easy to use, as well as offering
ef-ficient availability and logistics. We are also working on ways to reduce
our impact on our environment and climate. We do that by developing methods to
produce our solutions using a minimum of energy and natural resources, and by
reducing negative ef-fects on the environment. We use steel in our prod-ucts.
It’s one of few materials that can be recycled an infinite number of times
without losing any of its properties. That means less carbon emissions in na-
ture and less energy wasted.
