1. GENERAL INFORMATION
VTR fans are intended for mechanical exhaust ventilation in residential buildings, collective
housing and public utility buildings. They are the basis for the entire ventilation installation,
which includes a duct network, fire dampers, exhaust grilles, diffusers and other components.

HD automation
Integrated into the VTR fan, the HIGROdynamic automated system adapts the fan speed
to the opening degree of the HIGRO
®
AERECO diffusers and grilles. This means that the
electronic system lowers the fan speed at low flow volumes, adapting to the lower airflow
resistance in the ducts, and increases the fan speed at higher airflow volumes caused by the
open dampers of the hygroregulated grilles. The HIGROdynamic automated system prevents
improper operation of the ventilation system, in particular excessive noise from grilles and
diffusers at low humidity. The automated regulation of operating parameters reduces the
fan's energy consumption.
ATTENTION!
The compact design minimises
the necessary installation space
on the roof. The fans, thanks to
their flexible work and adaptation
to the network parameters, can
be used in buildings of different
heights.
