Decentralised ventilation SEVi 200U - reveal variant

The external closure of SEVi 200U (Undercover) is visually inconspicuous in the window reveal. The good ventilation values are not impaired by this.

The SEVi 200 Undercover consists of a fixed pipe (Ø = 200mm) made of PPs (polypropylene) flame retardant, for installation of the ventilation system in properties with various wall thicknesses from 400 mm. The ventilation system is fixed in the PPs pipe. It consists of an EPP (expanded polypropylene) casing. This material has a strong sound-absorbing and insulating effect.

An extremely quiet reversible high-performance fan from Fa. Papst operates in the housing. A high-tech ceramic (specific heat capacity 877 J/kgK) is implemented as heat exchanger. The specially designed outer bonnet with wind protection function prevents water from entering the ventilation system. In addition, a dust filter (optional pollen filter) is inserted into the system for protection against external influences (the filters are very easy to change).
