The DUPLEX-S 1600, 2600 and 3600 ventilator units are
a new patented design designed for comfort ventilation with
the highest heat recovery efficiency and for warm-air heating
of all types of public and commercial buildings.
The units are available in multi-purpose design, i.e. for
installation on the floor or beneath the ceiling. In addition
the unit sides may be interchanged, i.e. supply and exhaust
air ports can be used conversely, allowing installation
flexibility.
The DUPLEX-S 1600 also includes alternative ports that
can be interchanged and used on site as side ports.
The units are designed as compact ventilators comprising
of two independent high-efficiency EC fans with spring-
