  • Sale -39% Active Air Inline Carbon Filter, 8"x30" Active Air

    Active Air Inline Carbon Filter

    The next advancement in carbon air filtration is here! Active Air Inline Carbon Filters are installed inline for maximum versatility in filter and fan placement. The carbon filter is no longer limited to being located inside the grow room!  Most carbon filters are designed to be "terminal"——they are closed at one end and must be at the end of the ducting line. Active Air Inline Filters can be located wherever you want them to be, because they do not pull air through a mesh on the filter's body——the filtration occurs within the interior of the filter body, which is solid on the exterior. Active Air Inline Carbon Filters are perfect for grow tents, cabinets, small spaces and other applications where the option to not have the filter in the room is desired due to space restrictions. They can be located outside the grow room and a run of ducting can be extended from them into the room to extract the air and filter it. These versatile filters allow the option to locate the fan outside of the room as well, if desired. These filters also feature superior two-stage air filtration design: air is filtered once as it enters the filter, and then again as it exits.  Two-stage filtration design Carbon bed depth of 1" Dual airflow direction 750 CFM 8" flange
