Fits in DN 80 mm (3 inch) ducts, Determine the air volume and sound attenuation by removing punched parts (see fotos), The in duct ESD sound absorbing element is a simple solution for setting the volume level and reducing sound in central ventilation systems. It reduces noise coming through the ducts of the ventilation system, such as road noise.
The muffler is ideal for retrofiting installations, for the correction of individual volume flows in certain zones with simultaneous sound insulation. Furthermore, it is well suited as a sound absorbing element with a short depth construction for the reduction of air noise and telephony sound, Several elements in succession further increase the sound damping (ex. 2 = 2x dampening)
Instillation: First, free the desired amount of pieces. More removed pieces equal more airflow but less noise insulation and less pieces removed mean more noise insulation but less airflow. A ventilation system serves the purpose of ventilation and should therefore not be completely closed as this could cause other undesired effects (mold formation). Once the quantity of removable pieces have been adjusted, the muffler should be pushed into the ventilation tube. For further improvement of the s
We purchased a TAIMIKO Commercial Kitchen Knee Operated Hand Wash Sink. It was the best price we could find even with shipping to NZ. Once we brought we got some red flags from Gmail but with communication with Bigamart it did arrive and is exactly what we ordered. Thank you for all you time helping us we really appreciate it. Would use again.

I received this watch as a gift from a fellow Watch collector, usually high-end Swiss Chronographs. I can assure you this watch will not disappoint You in any way. I wanted to not like it as much as my other watches, just to be a watch snob. However I’m extremely pleased with this watch and am happily surprised at its quality. I really appreciate this gift and wouldn’t hesitate to get another for myself or as a gift for someone who appreciates a nice watch. For the price you really can not make a better choice in a time piece.
