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.

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.

6. IDENTIFICATION
MARKING_______________________________________________________
Example of smoke exhaust fan identification:
mcr Monsun - 50 / 4 - 1.5 - 5 / F400
7. INSTALLATION_____________________________________________
The mcr Monsun smoke exhaust axial fan is designed for vertical and horizontal installation. The
equipment can be installed indoors or outdoors.
7.1. Pre-assembly inspection____________________________________________________
Each smoke exhaust fan is factory inspected by the manufacturer prior to packing and shipping. Upon
unpacking the delivered smoke exhaust fan, visually examine it for any damage in transport.
The motor shaft should rotate with the rotor without evident resistance or scraping.
7.2. Location and assembly_______________________________________________________
The mcr Monsun smoke exhaust fan can be installed horizontally or vertically. Prior to installation, verify
the load bearing capacity of the roof, floor, wall or ceiling where the equipment is to be located.
If the smoke exhaust fan is to be installed vertically on a roof, prepare and secure an opening in the roof
slope at a diameter that fits the equipment. Set a special roof fan base over and aligned with the opening,
and suitable for the roof type, the fan weight and the fan diameter. Level out and anchor the roof fan base
to the roof slope. Put the fan on the roof fan base. Fasten both the equipment to the base with bolts.
Secure the fan exhaust with a roof exhaust vent assembly to prevent rain water and snow from entering
the building through the ducting.
When installing the smoke exhaust fan vertically on a baseplate, put the equipment on type PP vertical
support. It is recommended to bolt vibration dampers to the support in order to reduce the vibration from
the fan operation.
When installing the smoke exhaust fan horizontally, fasten type SW bottom feet to the fan housing flange
with bolts. Set the finished assembly on previously prepared vibration dampers, which have been
previously anchored to the substrate or a framework. The anchor and bolt diameter and length must match
the equipment size.
When installing the smoke exhaust fan below a ceiling, do this on a suitable support structure. Install the
vibration dampers and bottom feet on the support structure, then place the smoke exhaust fan there. The
anchor and bolt diameter and length must match the equipment size.
Connecting the smoke exhaust fan to the (smoke exhaust) ventilation system:
Connect the ventilation duct to the smoke exhaust fan via type PK counterflanges. Use type KD flexible
joints, which need to be fastened to the smoke exhaust fan to reduce the vibration transmission to the
ducting. This assembly is installed by sealing the joint interfaces [with high-temperature silicone] and
tightening the two parts with the bolts sized according to the fan size. The ventilation duct must not exert
loads on the smoke exhaust fan or other components of the assembly. The ventilation duct must be
supported by independent bearing slings. If the suction and forcing is free-flow, secure the smoke exhaust
fan intake and exhaust with type SO safety mesh. If the smoke exhaust fan is operated within a ventilation

system, secure the intake and exhaust sides from entrainment of foreign bodies or accidental entry of
persons, animals, etc.
When installing the smoke exhaust fan, secure the installation site and all involved structures, and prepare
passage and access ways for all personnel not involved in the installation. The smoke exhaust fan must
be assured to enable inspection and servicing.
Example horizontal installation of the smoke exhaust fan
Notes:
 Secure the system against entrainment of foreign bodies and accidental entry of persons, animals, etc.
 Ensure that the fan is aligned with the system components.
 The automatic non-return damper must be levelled for good performance.
 Install a straight duct section with a min. length of 2.5xD on the fan pressure side.
 Seal the system joints with silicone or other high-temperature compound.

7.3. Electrical connections_____________________________________________________
Having properly located, placed and fastened the smoke exhaust fan, connect the equipment to the
relevant electrical system wiring. Lead the wiring through the gland and into the electric box on the fan
housing; then connect the wiring to the terminals according to the diagram shown in the box. The electrical
wire with the proper fire resistance rating is installed in standard by the manufacturer between the fan
motor and the electric box. Each fan motor must be connected to the electrical power system over a safety
switch. The safety level must be present according to the nominal current draw of the fan motor. The
protective earth shall be made according to relevant electrical engineering standards.
Once the smoke exhaust fan has been commissioned as a part of the system, measure the current draw
and verify that it meets the motor rating plate data. The smoke exhaust fan current draw in steady operation
must not exceed 1.1 times the current ratings.
The electrical power supply from the control cabinet to the fan power junction box must guarantee
uninterrupted operation in the case of a fire. This can be achieved with high temperature resistant wiring
or with protective tubing and proper safe routing of the electrical power system. No external
service/maintenance switches are to used, which is to prevent inadvertent shutdown of the smoke exhaust
fan (with the sole exception of the fan-dedicated service switch with remote indication of current circuit
switching). The smoke exhaust fan control cabinets must be powered directly from mail switchboards with
guaranteed uninterrupted power supply, even if the entire building is cut off from the power grid. If a main
fireman's switch is installed to isolate power from the entire building, the smoke exhaust fan power supply
must be independent from that solution and assure normal operation in the case of a fire.
If the system uses the service switch, install it outside of the fan casing, i.e. at a min. distance of 9 cm,. on
a bracket bolted to e.g. the fan casing flange [see the figure below].
