Review: Good performance - The sound absorber work very well. I had to mod them slightly in order to fit into the 4" waste pipes that had been used for the vent holes. I did that by fully wrapping the sound absorbers with 50mm wide Armaflex self sticking foam tape. Initially I did wrap only one of the sound absorbers and left the other one slack. So I found out, that not wrapping the sound absorber does lead to a poor performance, if the internal diameter of the tube is wider than the outer diameter of the sound absorber. In 100mm ventilation duct tubes the wrapping would not be required. The permanent noise from the stream outside has reduced dramatically. Entering the kitchen the first few days felt like coming into a void spot, as if something was missing. Although please take into consideration that the noise reduction does not happen magically. If you expect your fan to be less audible and the fan is fitted on the inside then the noise reduction would be on the outside only.
Review: Would recommend - Having had an air vent causing noise issues, but covering it only causing damp issues, this was a life safer. Though the noise isn’t fully dampened, it’s made a huge impact, and option to remove and add segments again makes it versatile enough to make a difference. The soft sponge makes its installation easy

## Questions & Answers

**Q: What would be the equivalent ventilation area with all the foam inserts removed for the 125mm diameter i.e. would it be 4400mm2?**
A: MsCabbage,thanks for your question. The equivalent ventilation area with all of the foam inserts removed would be 5600mm², so 700mm² per foam inserts. You made a pretty good calcuation with 4400m².We wish you a wonderful day!Klimaparter

**Q: If using several of these in the same duct is the equivalent ventilation area still 700mm2 per piece removed?**
A: MsCabbage,thanks again for your question. Yes, as long as the holes are perfectly aligned with another, the equivalent ventilation area is still 700mm². Please be careful when putting them in back to back.happy silencing,Klimapartner

**Q: Hi, would this be suitable for a portable air con vent hose to reduce the exhaust noise outside?**
A: Thank you for your question. Yes, these sound absorbing devices will reduce all noises regardless where the foam is inserted. If you have any further questions, please do not hesitate to ask. 

Sincerely

Klimpartner

**Q: Is this product available for 150mm ducts?**
A: You can not use this ESD 100 because it is suitable for DN 100 pipes. Since there are none in DN 150, you would need to use DN 160 and adapt it to DN 150.

### ⭐⭐⭐⭐⭐ A great help in reducing external sounds coming through vents.
*by M***Y on 7 December 2025*

I fitted these silencer units to a number of ducts where I had also fitted external cowls over the vents. As the property is in a very windy coastal area, the cowls were necessary to greatly reduce the force of air through the vents but they appeared to add to the sound coming through the ducts. The silencer units helped greatly in reducing the sound of the wind effects and other sounds coming through the ducts.
