Loading more carbon, light weight, IAV more than 950mg/g, 2 flange
has aluminum and chromed one. Good out appearance, flange could be
directly connected with fan, also could be connected with outlet of
fan. Flange base is conic design according to aerodynamics
principle, which makes full use for base carbon. Besides, under
flange is plastic seal. After half year using time, unfolding
screws fixed flange and base to switch position for flange and
base. In this way, base carbon could be full used and extended
filters using life. Perforated filter mesh provides 53% open area.
Non glue eco fabric as pre filter, good permeability, thinner fiber
