Filters Direct carbon filters are used for the filtration of gaseous particles. The use of either loose charcoal or media impregnated with activated carbon enables high efficiency for gases. Various types of carbon filter are used, depending on the application, contamination and concentration in question. The filters can be largely split into three fields of application: Although various types of carbon filter are used, depending on the field of application, it should be noted that the carbon does have to be impregnated to guarantee suitable efficiency for both acidic and alkaline gases. Furthermore, the optimum product variant has to be selected on the basis of the concentration in question. In the case of high concentrations of gas, for instance, a cylinder containing loose carbon pellets is used, as it has a higher adsorption capacity than a pleated filter element.
ConstructionOur activated carbon filters are available in the form of elements, which can be filled with loose activated carbon pellets. These filters are usually refillable and are further characterised by their combination of high adsorption capacity and low flow rate. In addition, Filters Direct has an extensive range of filters which comprise a relatively small amount of activated carbon sandwiched between two layers of filter media. The flow rate of these filters is particularly high, while their adsorption capacity is low. In the case of extremely high concentrations of gases, it is also advisable to use stainless steel.
ApplicationsActivated carbon filters are widely used in airports, record offices, museums and the semiconductor industry. The filters can be installed in either standard Filters Direct holding frames or frames specially designed for the activated carbon cylinders. It is important that separate filters are fitted in front of and behind the carbon filters. A pre-filter is required to prevent the activated carbon filter from becoming clogged with dust particles. An after-filter is also required to avoid the possibility of activated carbon particles entering the airflow.
Installation• Ensure that no leakage can occur (new gaskets can be supplied together with filters) • Ensure that the frame and the cabinet in which the new filter is to be fitted are cleaned first • Activated carbon pellets may be spilled either during installation or throughout the life span of the filter; ensure that these are removed before the system is turned on • Maintain records of the filters installed; note the date, type and initial resistance |
