Our mobile filter unit WINDfried is used in schools and other public spaces to protect against coronavirus following very positive test results.
The high-performance filters used are generally very quiet in operation. Normally installed in the ceiling of a clean room, their operation is barely audible. However, when using our quickly developed, mobile filter unit WINDfried, which is set up openly in a room, we sometimes received feedback that the filter noise is annoying in the long term.
With our enhanced WINDfried 2.0 model, we were able to significantly reduce the noise level once again by enclosing it. Pupils’ concentration is no longer disturbed, even in a completely quiet working atmosphere.
We hope that this will help to ensure that our children get through the winter safely.
