Benefits
Stairways Pressure Differential Systems
Systemair is the leading company in combining differential pressure
and smoke extracting in one system with EC technology.
Ten benefits of electronic
overpressure systems
1.
Faster self rescue: Fire escape stairways are
recommended even if other arrangements are
permitted for escape and rescue routes. People
evacuation is faster through smoke-free stairways
or stairways with less smoke – the panic risk can
be reduced.
2.
Faster rescue by others: On electronic overpressure
systems, the air supply of the fans can be switched
to the maximum air volume by a firefighter's switch.
This enables pushing back and leading smoke away,
even at high fire temperatures. The pressure in the
stairway exceeds the standards limitation, and a
time-consuming installation of mobile fans, allowing
a clear view, in many cases is unnecessary.
3.
More flexibility during fire-fighting operations:
Mobile fans placed in the building entry can become
a "tripping hazard" for emergency task forces,
particularly with regard to connections such as
cables and hydraulic hoses.
The overpressure ventilation technology is not new.
It was invented during the eighties as an appropriate
element within fire protection concepts for skyscrapers.
The manufacturer Systemair was instrumental in pushing
the development of an important improvement: the
electronic control for pressurisation ventilation fans.
This system provides higher security for self-rescue and
especially for the fire brigade.
Benefits
Nowadays, an air-tight building with few leakages
demands higher requirements for the planning and
installation of smoke extraction concepts.
Not only are influences from outside, such as
temperature and wind, relevant for the design of
pressure differential systems but also smoke extraction
fans which create a negative pressure inside the
building in case of fire. This negative pressure inside
modern buildings can no longer be neglected and has a
significant influence on the pressure distribution in the
building and consequently on the pressure differential
systems. The latest development of Systemair combines
both systems into an overall concept with energy
optimised EC technology.
4.
7.
Reduction of construction costs: Openings for
air outlets are not required. Control dampers and
additional weather protection equipment are usually
not necessary.
8.
Reduction of operating costs: No complex adjusting
or cleaning of mechanical control dampers.
9.
Steady precision during life cycle: Electronic
overpressure systems automatically compensate
potential leakages due to normal wear and tear of
the building.
5.
6.
Higher security for emergency task forces: High air
velocities combined with electronically controlled
ventilation reduces the concentration of flammable
gases and hot air in the zone on fire. This reduces
the risk of backdrafts and delays flashover.
Higher building protection: With the possibility
of overriding the set pressure with the electronic
overpressure system a faster access for the
firefighters is enabled. This reduces fire damages
which can be honoured by the assurance in certain
cases.
Reliability: Electronic overpressure systems are not
affected by wind loads, snow coverings or pressure
changes due to cold or warm supply air.
In case of fire, smoke gases are a
dangerous threat to escaping people
and can also endanger and obstruct
rescuers. Therefore, electronically
controlled positive pressure units are
the next step in fire protection.
The firefighters can use an ordinary
10. Architectural freedom: Huge air terminal devices or
high roof fans are not required.
switch to increase the supply air
fan volume to maximum air volume
and therefore less mobile fans
are necessary or even none at
all. Electronic pressure differential
systems are a great help for self
rescue. They also give an additional
protection from smoke gases for
the fire fighters during high fire
temperatures, provide a clear view
and allow a faster approach to the
source of fire.

Pressure Differential Systems
The stairways pressure differential system
with EC/AC driven motors
The pressure differential system
MUB-EC by Systemair and its AC
version needs no pressure relief unit
due to its control characteristics.
It offers a complete solution with
fewer components and actuators for
the pressure differential ventilation
in stairways and escape tunnels as
conventional systems. The system is
also available with smoke extraction
function* in EC and AC design.
The complete system as well as its
components meets the requirements
according to EN 12101-6 (Smoke
and heat control systems – part 6:
specification for pressure differential
systems). The adjusted EC motor/AC
motor regulation unit guarantees a
standardised regulation performance
plus very low energy consumption
during the ventilation process.
Design Example:
Our MUB-EC centrifugal fan unit is
used for residential buildings up to
eight floors. The capacity can be
increased by parallel operation of
two or more units. Higher buildings
normally require several supply air
units installed at different positions
in the stairway.
The self-regulating EC control panel
is connected to the fan unit via a
0-10V-signal. There is just one
standard 230 V cable necessary for
the control unit. The optional on/
off switch of the MUB-EC ventilation
unit can be directly wired to the
400 V power supply.
Systemair's complete solution
includes periferic controls like, connections for smoke detectors, manual
call points and a fire indicator panel.
Systemair designs individual
solutions for your application.
*Smoke extraction
Optional smoke extract fan certified
to EN 12101-3 (Smoke- and heat
control systems – part 3: Specification
for powered smoke and heat
exhaust fans).

Principle
Principle
New ideas and ways to overcome physical law.
The air flow at the open door to the fire room must be
kept at 0.75 or 2 m/s. If the entrance door is open for
escape, a large amount of air is led out of the stairway.
This air volume must be replenished additionally. Airflow
reduction allows the selection of a smaller sized fan and
especially smaller ducting. This enables cost reduction
and space saving.
