 mcr Monsun F300 smoke exhaust axial fans
 mcr Monsun F200 smoke exhaust axial fans
4. INTENDED USE___________________________________________________
4.1. Application_____________________________________________________________
The type mcr Monsun smoke exhaust axial fans are duct fans 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 indoors or outdoors: on suitable consoles with the motor in the vertical
orientation, or on the bottom feet with the motor in the horizontal orientation.
The fan overall compression ratio makes them compatible with ventilation systems characterised by
relatively high flow resistance.
The operating temperature range for fans in general ventilation systems is – 20°C
to + 40°C.
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 fan will not be fit for further
use.

 Two-speed two-functional fans
5. DESIGN AND OPERATING PRINCIPLE _____________________________
5.1. Design ________________________________________________________________________
1 - Fan housing
2 - Axial rotor
3 - Base support
4 - Motor base
5 - Electrical gland
6 - Electric box
7 - Rotor safety
8 - Motor, fire resistant at the specific temperature class
The smoke exhaust axial fan feature a steel housing in the form of a cylinder with connection flanges at
its end, intended for connection with the ventilation system. Inside of the enclosure the motor is located
and supported by the motor base. The rotor is set directly on the motor shaft neck. At the rotor intake and
in line with its centreline is an aerodynamic cone, which improves the flow performance. The fan can also
feature an air stator type KP, located inside of the ventilator casing on the rotor end.
The electric box is installed on the fan casing, to which the electrical wiring of suitable fire resistance is led
from the motor.
The rotors with the diameter D = [355; 400; 450] mm feature 9 blades, while the rotors with the diameter
D = [500-560-630-710-800-900-1000] mm are available with 12 blades.
The fan may work with various blade angles and numbers. This allows adapting the fan performance to
the ventilation system flow resistance characteristics.
Each fan features an inspection hatch which permits verification of the rotor sense of rotation.

6/19
5.2. Function ______________________________________________________________________
The single-functional fans do not run in standby. When 3-phase voltage is present on the electric box
terminals, the fan is started and running.
The two-functional fans run at low speed (RPM) to handle general ventilation under normal conditions.
When the fan receives an alarm signal, it automatically starts running with the second speed, which is
higher than the first one.

 Type KD flexible joint
features a laminar design; it is terminated with a flange with the holes sized and spaced as on the fan
housing flange. The special fiberglass silicate textile ensure durability at 400ºC for 120 min.
Type KD flexible joint is used to eliminate the vibrations transmitted from the fan to the ventilation system.
It acts as a vibration damper. It is also used to compensate for thermal elongation. The fan integrated in a
ventilation system should feature the flexible joint on the suction and pressure sides.
