Aspiration reduction for soiled areas and deep-freeze areas
During use in deep-freeze areas, the flexible aspiration reduction expands in the air sampling
openings and pushes the ice away during blowing out. The special plastic clip ensures that the
aspiration reduction remains at the defined location.
As the clips are more stable under pressure and the elastic rubber insert significantly
improves the cleaning effect, they are used for all plans and designs which require a blow-off
system due to environmental influences (e.g. increased exposure to dust).
Notice!
The standard AF-x aspiration reducing film sheets and the marking tapes are not suitable for
use in low-temperature areas.
The aspiration reductions with plastic clips are available separately.
