A combination of biological, chemical and physical processes makes our activated carbon filter mats so powerful and durable.
Activated carbon has an extremely large specific surface area due to its porous structure. This large surface area offers many binding sites for molecules and functions in a similar way to a sponge. Thanks to the natural properties of activated carbon, odors can be filtered sustainably and effectively.
Activated carbon can form chemical compounds with certain molecules. This happens primarily with molecules that are chemically reactive or polar, such as hydrogen sulphide (H2S) or ammonia (NH3), substances that result from rotting processes in ducts and in exhaust systems. COALSI's special mats are impregnated with chemical reagents to increase the chemical reaction and convert odor-intensive substances into less annoying or odorless substances.
Activated charcoal contains macro, meso and micropores. The micropores are particularly effective at adsorbing small molecules, which are often responsible for odor. Thanks to the unique structure of COALSI filter mats, the activated carbon has a particularly large surface area to which molecules from the air are bound.
Microorganisms from the exhaust air settle on the loosely structured PU mat. The exhaust air flowing through supplies the microorganisms with nutrients, which activates them and multiplies. Hydrogen sulfuric substances are effectively broken down and filter performance is significantly increased.
Bio-chemische Reaktionen in der Kanalisation und der Industrie sorgen für unangenehmen Gerüche, die aus Kanälen und Abluftrohren austreten. Die umweltfreundliche Art, dem Gestank zu begegnen, ist, Bakterien gegen Bakterien ins Feld zu schicken.
Die mit speziellen Mikroorganismen fermentierten Hybridmatten von COALSI filtern die Geruchsstoffe, so dass der Kanal weiterhin „atmen“ kann.
Mikroorganismen aus der Kanalluft setzen sich auf der locker strukturierten PU-Matte ab. Die durchströmende Abluft versorgt die Mikroorganismen mit Nährstoffen. wodurch sie aktiviert werden und wachsen. Schwefelwasserstoffe werden wirkungsvoll abgebaut und die Filterleistung deutlich gesteigert.
Durch mechanische Verfahren werden bestimmte Stoffe filtriert und zurückgehalten.
Im Aktivkohlematerial des Filters werden Gasmoleküle zurückgehalten und angereichert. Die Oberflächen wirken kataklytisch und spezielle chemische Stoffe puffernd oder absorbierend.
The activated carbon used in our filters consists of more than 90% carbon with a large internal surface area (approx. 1200 m²/g). 4-5g of charcoal therefore corresponds approximately to the area of a soccer field. This area is used to adsorb unwanted, odor-causing substances from the air.
To increase the functionality of the filter mats, an ionizing fleece is integrated between the two activated carbon filters, which further increases the lifespan and reactivity of the activated carbon.
The COALSI filter mats consist of three different mats: a coarse-pored gas distribution mat to optimally distribute the incoming air over the surface, the ionizing fleece (ITS mat) and a fine-pored activated carbon mat to neutralize the odors of the exhaust air.
There are special impregnations for cases of hardship when activated carbon alone cannot filter all gases out of the air. Compared to the standard mat, these are even more effective against:
alkaline gases, e.g. ammonia, amines
acidic gases, e.g. sulfur compounds
hydrogen sulphide
