Filter Life

The application makes the difference.

Ge­ne­ral­ly spea­king the pro­tec­tive ven­ti­la­ti­on of the ope­ra­tor ca­bin nee­ds to of­fer the same type of pro­tec­tion as a gas mask (re­spi­ra­tor).

This me­ans, it nee­ds to pro­vi­de bre­a­thing air free from any ha­zar­dous con­ta­mi­na­ti­on, such as air­bor­ne par­ti­cles, fun­gal spo­res, bac­te­ria, foul odors, dan­ge­rous fu­mes and to­xic ga­ses.


Filter replacement for guaranteed protection

Any fil­ter has only a spe­ci­fic hol­ding ca­pa­ci­ty. As soon as this ca­pa­ci­ty is re­ached, the ef­fec­tiven­ess of the fil­ter will de­crea­se and the cor­rect func­tion of the pro­tec­tive ven­ti­la­ti­on sys­tem is not gua­ran­te­ed any­mo­re.

Howe­ver, it is not pos­si­ble to ge­ne­ral­ly de­ter­mi­ne the ma­xi­mum fil­ter life, sin­ce it lar­ge­ly de­pends on the exis­ting am­bi­ent con­di­ti­ons. SEKA has com­pre­hen­si­ve ex­pe­ri­en­ces in this fi­led and is able to sup­ports its cust­o­m­ers.

Each pro­tec­tive ven­ti­la­ti­on sys­tem from SEPA co­mes with a con­trol ter­mi­nal for mo­ni­to­ring and ope­ra­ting the sys­tem. An easy-to-read dis­play at the con­trol ter­mi­nal con­stant­ly in­di­ca­tes the pre­sent load con­di­ti­on of the dust fil­ter. As soon as the fil­ter has re­ached its li­mit, the ope­ra­tor will re­cei­ve a re­spec­tive warning si­gnal.

In­de­pen­dent from their load con­di­ti­on HEPA fil­ters should prin­ci­pal­ly be ex­ch­an­ged at least af­ter one year of ope­ra­ti­on. This could take place as part of the man­da­to­ry an­nu­al UVV in­spec­tion of the sys­tem.

SEKA re­com­mends the ex­clu­si­ve use of high-qua­li­ty fil­ters made from fi­ber­glass mats.

Replacement as required

Re­fer­ring to the re­pla­ce­ment of ac­tiva­ted car­bon fil­ters the­re is also no ge­ne­ral rule. Sa­tu­ra­ti­on of such fil­ters can­not be de­ter­mi­ned by any sim­ple me­ans. Es­pe­cial­ly co­lor­less and odor­less sub­stan­ces are dif­fi­cult to de­tect. Of­ten this is the case af­ter con­ta­mi­na­ti­on of the bre­a­thing air in­si­de the ca­bin is hig­her than the per­mit­ted le­vel.

That is why SEKA supports its customers in choosing the right filter.
