Activated charcoal filter
VOC / odour reduction
Odour emissions are not only unpleasant and annoying – they can also be harmful to health. Volatile organic compounds (VOC) or inorganic compounds such as hydrogen sulfide (H2S) and ammonia (NH3) are the culprits here. There are maximum levels of such components in exhaust air, which must be observed. The odour threshold is much lower than the threshold, however, meaning that minimal concentrations still cause considerable odour pollution. Activated charcoal effectively reduces these components. The exhaust airflow is guided through an activated charcoal bed at low speed. The activated charcoal adsorbs the hazardous substances from the exhaust air and binds them to its surface.

Markets
- Tobacco
We have been an innovative partner to the tobacco industry for over 50 years. As a system supplier of exhaust air cleaning and odour reduction systems, we are established worldwide in the field of cigarette manufacturing. With our pneumatic transport systems, central vacuum cleaning systems and machine cleaning systems, we pursue our main goals: Environmental protection, energy efficiency and increasing the tobacco yield in the tobacco industry. We improve the Primary and Secondary sectors with effective and patented technologies.
- Pet food
There are numerous process steps in the production of pet food - be it extrusion, drying, cooling, machine extraction or even the cooking process for wet food. During the processing of wet and dry pet food, dusts and odorous substances are released into the exhaust air, which can strongly pollute the environment. Riedel Filtertechnik offers a wide product portfolio with individual solutions for pet food production. From dust extraction and dedusting of conveyors, extruders as well as dryers to the reduction of odour emissions, everything is covered.
- Compound feed
In compound feed production, odour-intensive substances are often added depending on the recipe. As a consequence, odour emissions are produced which can pollute the environment. The grinding of fine, dry ingredients and the pelleting process also generate dust emissions, which we control with our filter systems. To reduce odours, we use our COPLAS clean technology, which uses neither water nor chemicals for sustainable production and generates no waste products.
- Food
Cereals, oil or milk powder - food production is characterized solely by the variety of food products. Numerous process steps, such as extrusion, drying, cooling or product packaging, are run through for their production. The result: dust or strong-smelling odor emissions that are inevitably released into the environment and are subject to strict limits. In order to be able to comply with these, we offer a wide range of products in the field of dust removal through to the reduction of odour emissions.
