① Soundproofing
The noise reduction effect has been proved from the noise value of 97.7 dB to 87.4 dB (reduced by 10.3 dB) after the installation of Fuji ZET.
(Measured at a distance of 5m in the horizontal direction)
 
② Safety
The compact shape makes the working tool more visible, the work efficiency is excellent and it's also safe and secure.
 
③ Breaking ability
By using special rubber material, it has a structure to release the exhaust promptly by the expansion and contraction motion of the swirler wing and the bellows part of the soundproof chamber without lowering the striking force and exhaust efficiency.
 
④ Durability
Synthetic rubber added on natural rubber. In addition to raising the sound insulation and muffling performance, we developed a rubber material with new properties that is good in terms of oil resistance, weather resistance, aging resistance and other features.
 
⑤ Usability
Since it is lightweight and compact, the workability is very good. Easy attachment and detachment is possible by simply fixing with a hose band.
