| For the vulnerable drink (requirements on bacterium ratio), Vaero designed |
| the high-efficiency air conveyor. It enhance the filtration efficiency by |
| setting a high-efficiency filter over the standard-efficiency filter at the fan |
| entry, and put the PET plate cover on both sides of the conveyors, which |
| prevents blowing the ambient air into the bottles. |
| High-efficiency filtration make it possible to change some hot-filling |
| into cheap aseptic ˇ°cool-fillingˇ±. |
