3. Intended use and principle of operation
3.1. Intended use and scope of application of iSWAY-FC®, iSWAY-
WFC®and iSWAY-RFC®units
The iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®product range is designed to generate and
maintain overpressure in protected spaces to prevent them from becoming smoky.
The iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®product unit should be used in construction
works for which pressure differential systems are designed with the following parameters:
•the volume flow rate of air supplied to the protected space to generate the required
overpressure or to provide an adequate airflow velocity through open doors, separating
the protected space from the unprotected space, is between 200 and 50500 m3/h for the
iSWAY-FC (with AFC/ARC ventilator), from 1500 to 75000 m3/h for the iSWAY-FC (with AJF
ventilator) and between 200 and 49500 m3/h for the iSWAY-RFC and between 200 and
42000 m3/h for the iSWAY-WFC;
•the required overpressure in protected spaces with closed doors between 20 and 80 Pa;
•the total air resistance on individual storeys, from the doorway between the protected and
unprotected zone to the place where the air is discharged outside the building (on a given
storey): between 0 and 42 Pa;
•the minimum leakage, including air flow from the zone where the overpressure is
maintained, is between 200 m3/h and 36000 m3/h –in case of AFC, ARC, HCBT and iSFS
ventilators.
•the minimum leakage, including air flow from the zone where the overpressure is
maintained, is between 1500 m3/h and 50000 m3/h –in case of AJF ventilators.
The iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®can be used in pressure differential
systems, where the air is extracted from the fire floor. The air exhaust system:
-escape (openings in external walls, ceilings, e.g. tilt windows, dampers, etc.);
-gravitational (e.g. fire ventilation shafts);
-mechanical (e.g. smoke ventilation system).
3.2. Operation principles of iSWAY-FC®, iSWAY-WFC®and iSWAY-
RFC®units
The iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®unit is designed to create an overpressure
of a preset value in any smoke protection space (fig. 3.1. - 3.6.), e.g. in the stairwell space, in the
rescue lift shaft, in the fire atrium, in the crane shaft for rescue teams, in the evacuation corridor
with all doors closed. In the event that a door is opened between the pressure protected and
unprotected space, the iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®shall ensure, in conjunction
with the designed air discharge system, that an amount of air is supplied to the protected zone at
which the air velocity through the open door reaches the declared value (depending on the class
of the designed differential pressure system).

Generating the required pressure value when the protected space is closed and ensuring
adequate air velocity through open doors connecting the protected space with the unprotected
space, prevents infiltration of smoke and hot fire gases into the protected space, ensuring that
escape routes are maintained and that rescue and firefighting crews are able to reach the
protected space in a smoke-free state (possibly in a state of slight smoke, at which it is possible
to carry out evacuation and rescue and firefighting operations). The supply of air to the
overpressure protected space can be carried out using a single supply point, as well as a multi-
point supply.
The amount of air supplied to the protected space (e.g. staircase) during the operation of the
pressure differential kit is variable. It results from a different air demand when device is
generating the required overpressure in the protected space (with all doors between the protected
zone and the unprotected zone in the closed position), and another when device is generating the
required speed of air flow through any door dividing the protected zone and the unprotected zone
that has been opened.
In the case of the iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®units, the above mentioned change
in the air supply is realized by using an MAC-FC controller and a frequency converter, which
controls the fan performance by changing the fan motor speed.
In the case of the MAC-D-MIN controller, the change of the supply air volume is realized by means
of a control damper with an electric rotary actuator.
The iSWAY-FC®, iSWAY-WFC®and iSWAY-RFC®pressure differentials provide continuous
monitoring of the overpressure value in the protected space in relation to the adopted reference
pressure. The use of the MAC-FC controller, which sends a control signal to the frequency
inverter, and the MAC-D-MIN controller, which sends a control signal to the control damper,
means that the pressure differential system does not require the use of overpressure relief
dampers, which remove the excess air when the permitted overpressure threshold is exceeded.
This is particularly important for installations in which large air flows are supplied to the protected
space in order to provide normative pressure and flow criteria. As a result, large mechanical flaps
are required, which may be difficult or impossible to implement.

4.2.iSWAY-WFC®
iSWAY-WFC®is a so-called wall device, whose construction allows for installation directly
in the wall of the building, between the space it protects and the space from which air is drawn to
secure the escape route during a fire. This reduces the space required to install the unit. The
protected space is insulated by the CDH inlet louvre, which is opened when the device is activated.
The automation cabinet Sza-FCK (power supply and control element of the iSWAY-WFC®set) for
this unit is available separately and must be connected to the unit via a cable route.

4.3. iSWAY-RFC®
iSWAY-RFC®is a so-called roof device, but it is a common name that does not restrict its
use under any circumstances. Its construction allows for installation on the roof of the building,
directly above the overpressure protected space, so that the air can be supplied directly through
an opening in the ceiling of the above space, where on the intake side there is only a roof air
intake and on the supply side an SRC damper blade isolating the protected space from external
conditions. There is also a possibility of installing air distribution on the intake and supply side in
such a way that the fan can be installed in the ventilation duct both inside and outside the
building, where isolation of the protected space from external conditions can be provided by
CDH-K intake louver or SRC-D damper. The automation cabinet Sza-FCK (power supply and
control element of the iSWAY-RFC set) for this unit is available separately and must be
connected to the unit via a cable route.

overall dimensions of iSWAY-FC/-WFC/-RFC units can be found in Chapter 8.
5.1. iSWAY-FC®
The basic version of the iSWAY-FC®unit is a compact unit (Fig. 5.1) which enables the iSWAY-
FC®to be installed in a designated technical room (ventilation engine room) or on a roof with a
dampers of double air intake system (Fig. 5.2).
Other typical versions of iSWAY-FC®are the air intake version (Fig. 5.3) and the vertical version
only for the smallest unit iSWAY-FC-0 (Fig. 5.4).
As an option, iSWAY-FC®has introduced a system to prevent the shut-off dampers from freezing
during precipitation and low temperatures. Special low-temperature resistant seals are used to
seal the dampers.
The system is used in the refrigeration industry and a 300 W directional infrared heater system,
which is set at the factory to -2°C. When working at a temperature lower than the set temperature,
the Anti-Frost system automatically switches on. The key elements for correct operation of the
throttle valve at low temperature were painted black to absorb the maximum amount of infrared
radiation. The remaining iSWAY-FC®interior components are left in bright colours to reflect the
radiation and direct it to the essential elements, which enhances the infrared beam.
To achieve the declared capacity of the air handling fan, a straight section of duct with a minimum
length equal to the diameter of the fan used must be provided directly behind the unit on the supply
side. If local technical conditions allow it, a 1 m long straight line is recommended.
