Vitovent 300
Ventilating virtually without energy loss
Energy saving is Vitovent 300's trump card.
The powerful heat exchanger recovers more
than 90 percent of the latent heat contained in
the stale air and uses it to heat the incoming
air. Thanks to the very efficient DC motors, for
each 1 kWh of electrical energy expenditure,
15 times more heating energy is recovered.
This means that in a living area of 150 m2 for example, you save around 300 l fuel oil
each year.
Cooling with night air
In winter, the majority of the heat contained
in the extract air is recovered through the
heat exchange function. In summer, the heat
exchanger is completely bypassed via the
integral bypass damper. The temperature
controlled bypass circuit allows cool outdoor
air to enter the rooms at night, thereby
ensuring a pleasant room climate.

The Fastflex flat duct system:
space-efficient and easy to install
The Fastflex system for air distribution is
precisely matched to the Vitovent 300. For
one thing, it makes it easier to install and
set up the domestic ventilation system,
and for another, it also saves space. Two
floors can be supplied simultaneously via a
single installation level. The flat ducts are
so versatile that they can adapt to suit any
structural characteristics and they are also
particularly stable and can be routed below
the screed in the floor insulation.
