ACCESSORIES
The airflow value must remain within a tolerance
range of + or – 20% from the nominal air flow
range.
The ducts must be set on the correct parameters,
in order to avoid their pressure drop to over cross
the pressure head that the fan can supply.
airflow 200 m³/h pressure drop 10.0 [Pa]
airflow 230 m³/h pressure drop 11.6 [Pa]
airflow 250 m³/h pressure drop 13.0 [Pa]
airflow 270 m³/h pressure drop 14.8 [Pa]
For pressure drops across the filter, refer to the fol -
lowing data:
Available pressure of the fan
The speed regulating system of the fan allows the
balance of the pressure drop, which is due to the
different lengths of the ducts.
VESTA80I is equipped with refrigerating system with air
condensing.
A condenser working with air is used (Isotherm mode)
when the environment air is under 28° C;
A condenser working with water is used (Integration
mode) when the environment air is over 28° C.
The air flow rate must be set on a parameter the closer
to the nominal air flow rate (which is 250 m3/h), in order
to avoid the risk of a reduction of the performance and/
or malfunctioning of the unit.
