The Nuaire SVT2 unit comprising fan/motor assembly, and
inlet & outlet silencers shall be certified for high temperature
operation at 300
O
C for 2 hours, the range shall have been type
tested to EN12101-3.
The units shall be either 2 speed or inverter driven providing,
low speed for day to day environmental ventilation and one off
operation for emergency ventilation (S1 duty). They shall also
be suitable for reversible operation.
Fully reversible options (i.e similar duty in both airflow
directions) are available, please contact Nuaire for details.
The unit shall have a unique mounting bracket, which shall
enable the bracket to be positioned as a “first fix” component
with the unit being fitted as a “second fix” component, avoiding
possible mechanical damage.
The Nuaire SVT2 unit shall have inlet guards for safety purposes
and also to prevent debris being sucked through the fan.
It also has a specially designed airflow deflector to
direct the jet stream from the fan at the required
angle sufficient to overcome the natural buoyancy
effect of the smoke. (see page 2 for adjusting).
EN12101-3 compliant, refer to EC certificate of
conformity, 0086-CPD-467873.
Handling
Always handle the units carefully
to avoid damage and distortion.
If mechanical aids are used to
lift the unit, spreaders should
be employed and positioned
so as to prevent the slings.
