FILTRATION
FC120-P SERIES This process extends filter life as the surface of the catalyst will not be covered by molecules trapped on it, thus enabling the process to be repeated. These filters will operate effectively in environments with temperature up to 70oC, and with relative humidity up to 80%. AES Environmental continues to push the design boundaries of its Direct Duct Fume Cabinet range; the FC-120P series has been developed for the safe containment of volatile compounds. The special P series features an explosion proof fan and can be configured with a dual bed of carbon or activated alumina to provide a wider range of contaminant removal. The P series is available in 1200mm and 1700mm widths to accommodate for the larger filtration surface area and specially selected fan and operating controls.
Air exhausted from the top of the cabinet is filtered by a one-stage filtration system. A prefilter protects the final filter system from particulates > 5μm. The final activated carbon filter incorporates carbon granules with a selected chemical impregnation to optimise the arrestance of specific vapours. Specific impregnations are available for the handling of a wide range of contaminants, including formaldehyde and glutaraldehyde, Alkaline odours, Ammonia and amines, Inorganic acids and acidic odours, H2S and mercaptans and HCN. Special adsorption filters are fitted for the capture of a wide range of vapours. Chemical impregnation of the carbon produces a chemical reaction similar to an oxidation process when the contaminant is adsorbed.
