Odour Control

Activated carbon has been utilised for many years to reduce fumes and gases from the air. Currently a wide range of carbons is available for this purpose in the continuous battle against the emission of unpleasant or even dangerous odours and fumes from a wide variety of sources. The ever-increasing awareness of this problem by the public health authorities and environmentalists has resulted in a corresponding increase in the use of activated carbon filters. The types of carbon most commonly used in the H & V Industry are grades 203C and 207C (or equivalents). A large variety of other activated carbons are available. some of which are specially impregnated for particular applications.

Carbon filters are desirable in many installations where airborne odours, chemical or toxic fumes are present and need to be reduced or eliminated. The carbon will adsorb the chemical molecules in the airstream in varying degrees according to the particular contaminants involved and the type of carbon utilised. It may be interesting to note that, when activated, one gram of carbon can have a surface area of approximately 1000 sq.m. Incoming air at city offices, industrial plants, airports, art galleries, museums etc., can be purified by passing it through carbon units fitted in the system. Also air from kitchens, industrial processes, sewage plants etc., can be extracted through activated carbon before entering the atmosphere, greatly reducing its impact on the environment and to comply with pollution regulations or focal authority requirements.

Activated carbon in its loose form can present problems in any installation since there is a tendency for the granules to move against each other causing bedding down, which produces dust and can also allow by-pass to take place. However, permanent suspension panels that are utilised throughout our range have the granules held together by a patented bonding process, and incorporate a non-woven fabric on both faces. This construction eliminates the problems described above, and produces a homogeneous biscuit of consistent quality with dimensional stability, thus producing an even resistance across the panel
