Silencer

Our silencer is a silencer that breaks the erroneous common sense that sound cannot be extinguished unless air resistance is applied. It is an environmentally friendly, future-oriented silencer that does not increase the load on air conditioning equipment due to excessive air resistance, which also saves power. The regenerated noise due to airflow is low enough that it cannot be measured.

Silence elbow

The silence elbow is manufactured with a flexible design concept that can be used in any installation environment, so it can be installed in ducts of various sizes. By installing an outside radius, it is possible to propose pressure loss and to support split production.

Silence chamber

The silencing chamber is manufactured in consideration of the installation space and duct size. We design one by one according to the needs of each site.

Silence box

The silencer box is compatible with the mounting dimensions of each appliance manufacturer, and the hanging position can be adapted to the needs of the site. In addition, the use of an anemo box designed by our company shortens the construction time.

Anti-vibration sound insulation sleeve

Our vibration and sound insulation sleeves suppress the propagation from the duct to the body penetration. By driving it in at the time of building, the sound insulation work at the penetrating part can be greatly reduced and the construction period can be shortened.
