Our activated carbon filters have a dimensionally stable round design, and are used in dust extraction and ventilating systems. They can effectively remove gaseous air pollutants harmful to health. The activated carbon will be adapted specifically to the substances to be removed, and will absorb noxious gases, reduce odours, and clean the exhaust air. Using these filters, businesses can observe the regulations governing air pollution control as provided for, e.g., in the German Clean Air Guideline ("TA-Luft"), and thus minimize adverse effects for employees and, more importantly, for local residents.
Operating principle
Raw gas flows through the inlet nozzles into the filter. The air to be cleaned is distributed homogeneously in the inflow space, and is then conducted evenly through the complete activated carbon fill. This fill is held in circular-shaped perforated sheet metal cassettes. While flowing through, polluting substances will be absorbed by the activated carbon, and the clean gas will be let off upwards through the clean gas nozzle.
Activated carbon saturation will progress from the outside toward the inside over time. The carbon fill will be replaced when the full saturation level has been reached. Clean gas can be released into the environment through a chimney which is either placed on top or installed separately. To guarantee or, correspondingly, keep up the filter's optimum function and performance, we recommend to remove the dust from the raw gas before feeding it to the filter.
