Zehnder ComfoSpot 50 is a decentralised ventilation unit with heat and humidity recovery using synchronous supply and extract air operation. It is often used in apartment renovations
as well as in new residential builds. The ventilation unit is suitable for venting individual rooms. An enthalpy exchanger, which ensures a high degree of heat and humidity recovery, is
standard on the unit, which has a positive effect on the room humidity and therefore provides a comfortable indoor climate. Zehnder ComfoSpot 50 can be installed with various outside
wall hoods or a reveal module for almost invisible integration of the external and exhaust air ducts in the window reveal.
