If the delivery address is a private residence (detached house or apartment building), the house name is required. Please note that delivery may not be possible if the house name is not provided. *Depending on the delivery location, the delivery date may be postponed and additional shipping charges may apply. *As delivery is made using a large vehicle of 4 tons or more, depending on the delivery location, customers may be asked to collect their package from the truck. *The driver will not assist with unloading. *If redelivery is required due to absence at the time of delivery, additional shipping charges may apply.

*When installing in the middle of piping, please be careful not to apply weight to the piping. *The outer diameter (D dimension) is made larger to enhance the sound absorption effect. Generally, it is screwed into either the intake or exhaust port where there is no piping, but if connecting to both, please install it in a position that is offset so that the outer diameter (D dimension) of both silencers do not come into contact. *For the high wind pressure two-stage type, please use steel pipes. *PVC pipes cannot be used.
