4. INTENDED USE___________________________________________________
4.1. Application_________________________________________________________________
The type mcr Pasat roof smoke exhaust fans are intended to remove smoke and heat generated in
indoor rooms on fire. The equipment facilitates evacuation of persons from the area on fire, protect the
building structure and its furnishing from high temperature, facilitate fire fighting, and inhibit spreading of
fire to adjacent fire zones.
The available versions include:
single-functional with single-speed motors;
two-functional, i.e. for general and fire ventilation and with two-speed motors.
The fans can be installed outdoors: on suitable consoles/roof ventilator bases with the motor in the
vertical orientation.
The fan overall compression ratio makes them compatible with ventilation systems characterised by
relatively high flow resistance.
The fan may force dry air only and with a maximum particulate content of 0.3
g/m³.
This fan is not intended for forcing air with viscous pollutants that may settle
on the equipment, and especially on its rotor.
This fan is not intended for forcing air with corrosive pollutants that may be
detrimental to the equipment.
The maximum actual rotor RPM must never exceed the nominal (rated) RPM
speed in operation.
Following operation in actual fire conditions, the ventilator will not be fit for
further use.
