TIP!
– Filter
The KWL compact unit is equipped with fine filters on the outside and extract air side as standard (DIN EN 13779).
The internal pressure-dependent filter monitoring system signals the necessity of inspection and cleaning or
filter replacement on the controller. Irrespective of this, a 3-month inspection is recommended. They must be
exchanged for hygiene reasons after one year of operation at the latest. If the filters are damp or mouldy, they
must be exchanged immediately.
Replacement air filters are also available online at
