PVI-HTSmoke exhaust fans for fire and car garages

FEATURES

Induction fans are designed for forced ventilation of underground car parkings. They are used, in normal conditions, to remove pollutants from the garage (i.e. CO2) and , in emergency conditions (fire), to convey smokes and other combustion fumes towards the evacuation shaft. The most relevant characteristic of the induction ventilation system is the absence of ducting and hence the following advantages are there:

  • Lower cost of the complete system.
  • Lower running costs.
  • Higher flexibility.
  • Lower vertical obstruction.
  • Lower maintenance cost.

PVI-HT fans are designed and manufactured according to the European Standard EN 12101-3 and have been certified by an Acknowledged Qualified Institute. PVI-HT range is suitable for continuous service at 40°C air temperature and, in case of fire (emergency) at 300°C for 2 hours (F300). The series is composed by two models with thrust of 50Nw and 100 Nw. Construction features:

  • Self supporting structure in steel sheet with corrosion resistant finish.
  • Backward bladed impeller with high efficiency in galvanized steel sheet, balanced according to UNI-ISO 1940.
  • Intake safety grid with anticorrosion treatment.
  • Two-speed asynchronous 3-phase motor, suitable for continuous service at 40°C and for 2 hours at 300°C (F300).
