命も長くなるため、それらを頻繁に交換しなくて済む。As a result, it is not necessary to provide an ozone decomposing device. On the other hand, if the ozone decomposing device is provided only by adding ethylene, the ozone decomposing device is provided as an auxiliary device. May be provided on the downstream side of the pump 13 for decomposing ozone, whose concentration has been reduced by the addition of ethylene, to detoxify the ozone and release it to the atmosphere. You do not have to change them frequently.
