Activated Carbon Filters

Guaranteed filter performance as needed.

Ac­tiva­ted car­bon is the most ef­fec­tive me­ans against foul odors, dan­ge­rous fu­mes and to­xic ga­ses in the at­mo­s­phe­re.

Such car­bon fil­ters are usual­ly made from co­co­nut shells or hard coal. Ac­tiva­ted car­bon is cha­rac­te­ri­zed by a lar­ge sur­face able to bind pol­lut­ants. Our fil­ters usual­ly of­fer a sur­face of more than 1,000 m2 per gram.

Filter quality:
Always the right type of filter

Using spe­ci­fic pro­duc­tion tech­no­lo­gies, the pore dia­me­ter and sur­face of ac­tiva­ted car­bon can be tailo­red ex­act­ly to the ap­p­li­ca­ti­on. Hard coal is con­side­red A class qua­li­ty which only matches spe­ci­fic pol­lut­ants. AX coal has a much smal­ler pore dia­me­ter and is the­re­fo­re ide­al for sub­stan­ces which eva­po­ra­te at tem­pe­ra­tu­res be­low 65° Cel­si­us.

In or­der to achie­ve a fil­ter ef­fect with a wide band­width that is ef­fec­tive for many ty­pes of pol­lut­ants the raw coal can be trea­ted (im­p­regna­ted) che­mi­cal­ly.

Active carbon filter:
A matter of know-how

The hol­ding ca­pa­ci­ty of an ac­tiva­ted car­bon fil­ter does not only de­pend on its mass, but also on fac­tors such as im­p­regna­ti­on, gra­nu­la­ri­ty, pore size and sur­face. Ano­ther vi­tal fac­tor is the air vo­lu­me flo­wing through the fil­ter.

The more air is pres­sed through the fil­ter the ear­lier it will be sa­tu­ra­ted. The re­sul­ting bre­akth­rough ef­fect will even­tual­ly al­low pol­lut­ants to pass through the fil­ter and reach the cle­an room.

Filter effect:
External fan as added benefit

Only if the fan is po­si­tio­ned in front of the ac­tiva­ted car­bon fil­ter, exis­ting air­bor­ne pol­lut­ants will pe­ne­tra­te suf­fi­ci­ent­ly deep into its po­res. For this re­a­son SEKA ex­clu­si­ve­ly of­fers pro­tec­tive ven­ti­la­ti­on sys­tems with fans moun­ted on the outs­ide of the fil­ter.

In con­trast to this push prin­ciple sys­tems ba­sed on the pull prin­ciple are only able to use a frac­tion of the ac­tiva­ted car­bon. This me­ans their fil­ter ef­fect is con­sider­ab­ly lo­wer than that of pus­hing sys­tems. In ad­di­ti­on, they also cau­se a con­siderable pres­su­re drop in­si­de the fil­ter. As a re­sult, the ac­tiva­ted car­bon will be sa­tu­ra­ted fas­ter with wa­ter va­por, which great­ly re­du­ces its abili­ty to ab­sorb pol­lut­ants.

Abek quality:
Against sulfur and ammonia

We only of­fer ABEK fil­ters for at­mo­s­phe­res cha­rac­te­ri­zed by a high con­tent of both sulphur-con­tai­ning ga­ses and am­mo­nia. Howe­ver, this si­tua­ti­on is very rare and only re­fers to very few ap­p­li­ca­ti­ons. In the case of a high le­vel of ha­zar­dous sulphur-con­tai­ning ga­ses, we re­com­mend the use of pure E coal fil­ters.

Our ac­tiva­ted car­bon fil­ters come in car­tridges. This al­lows the ef­fec­tive com­bi­na­ti­on of fil­ters with dif­fe­rent car­bon qua­li­ties, such as se­pa­ra­ted E and K fil­ters.
