Condition always within view
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.
Activated carbon filters:
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.
For this reason, SEKA offers a special service to reliably determine the filter life of an activated carbon filter in relation to the existing operating conditions.
For this purpose the very first activated carbon filter needs to be exchanged and sent to SEKA prior to the end of its expected filter life. We will then test the filter load of the activated carbon filter on the basis of the expected pollutant level.
Based on a specific filter load analysis, the filter life of the respective filter can be determined at least with reasonable reliability. There is also the option to adjust the type of coal used more precisely to the specific application.
