| 摘要 |
The present invention overcomes the limits of activated carbons, ion exchange resin beads and fibers, and liquid form ion exchangers for acid, base, or VOCs gases removal by providing a filtration assembly for the filtration of chemical contaminants and particulates from an air or gas stream, the assembly having a low pressure-drop structure. The filtration assembly includes a low-pressure drop chemical filter, a low-pressure drop particulate filter, and an air transportation device, such as a fan or blower, all combined in a housing.
