| Since introducing advanced noise reduction and vibration prevention technology from Canada in 1986, Taikisha has built a strong lineup of technologies in these fields. Below are descriptions of two of Taikisha's original technologies: a low-pitch, limited-focus silencer and a noise-reduction system for cleanrooms. |

Conventional silencers used to extinguish noise from air ducts have difficulty eliminating low-pitch noises around 100Hz.
Taikisha's low-pitch noise extinguishing silencer incorporates both absorption-type and cavity-type resonance equipment. The echoes emanating from the resonance machines interfere with each other: a penetrating noise sent in the direction of the noise and the reactive sound in the direction of the noise source are zero, thus they are effectively eliminated. The use of interference also reduces pressure loss.
This is the optimal system for facilities such as event halls that require superior sound elimination, and cleanrooms in which plug fans generate low-pitch noise. |

Non-boron generating, noise reduction system for cleanrooms
In cases where a glass wool is used in fan filter units and ducts as a noise reduction measure, it can generate boron and cause chemical contamination.
Taikisha provides a fan filter unit with no-lined duct and a silencer with PTFE covering the glass wool material. This precludes generation of boron. |
