The Rhino Pro Carbon Filter contains a fine granular carbon from Australia called RC412 – in laymen’s terms the world’s finest quality virgin activated carbon. Activated carbon is made in a unique manufacturing process, every grain of carbon is heated in a tank and exposed to both steam and oxygen, through this process the pore structure of the carbon is greatly increased. Activated carbon has the ability to scrub and clean air that passes through it, it can do this by attracting and trapping impurities and smelly air molecules in its super porous surface area. The Rhino Pro Carbon Filter has an outer mesh shell made of 1.6mm thick aluminium for lightness, and the base is cone shaped to optimize airflow. Rhino Pro carbon filters are specifically designed for cleaning air produced by indoor growers. Stale air is drawn through the filter by an extractor fan. The Rhino Pro Carbon Filter gives an approximate lifespan of 18 months (Rhino do say that when treated right their filters can last well over 2 years) Rhino Aluminum Ducting x 5m The ideal solution for venting air in, out and around THE grow room.
