IntroductionThe mechanical ventilation systems

shown in this catalogue resolve the prob-

lems connected to smoke extraction at

high temperature and are the ideal solu-

tion for emergency extraction in case of

fire.

Potential Risks in Fire Situation• release of gas and toxic substances

causing eyes to water and conse-

quent difficulty in escaping

• ashes can be suspended in the atmos-

phere leading to reduced or no visi-

bility

• development of very high tempera-

tures

• the increase of carbon monoxide and

reduction of oxygen in the air (possi-

bly leading to asphyxiation)

Function and Advantages of

Mechanical Ventilation in

Case of Fire

1. Mechanical ventilation removes

smoke and fumes produced by a fire

and by creating negative pressure (in

the ambient) it prevents smoke

spreading into other parts of the

building. This makes it easier for

people to escape and simplifies the

job of the fire and rescue services.

2. In enclosed areas, temperatures can

easily exceed 1000° C, causing com-

bustion from heat radiation and mak

ing any external extinguishing opera

tion useless. Keeping the tempera

ture relatively low (300°- 400° C) by

extracting hot air, can avoid the col-

lapse of support structures. In addi-

tion, the higher oxygen levels will

cause better combustion and thus,

for most materials, a lower produc-

tion of toxic smoke.

3. Mechanical ventilation allows the sit-

ing of the exhaust outlets away from

the fire. High temperature axial fans

are easily connected to a duct sys-

tem.

4. Mechanical ventilation allows the ex-

traction of cold fumes, which since

they remain at a lower level are dan-

gerous and are difficult to remove

using static systems.

5. Mechanical ventilation allows for ven-

tilation in normal circumstances

(clean air), using products with two

speed motors: at low speed for nor-

mal ventilation (so with lower noise

level) and at high speed for emer-

gency conditions. For this type of op-

eration, it is necessary to install the

fan with a dedicated power line that

automatically operates in case of fire.

CertificationEmergency Smoke Extract fan design and

installation is regulated by the European

standard EN12101-3, which establishes

the temperature ranges/operation time

certified products must comply with.

The SMOKEX® range is CE certified

to classes F300 and F400 and guaranteed

to operate at 300°C for two hours in

compliance with EN12101-3 standard by

the Applus laboratories in Barcelona.

Description

The belt driven double inlet CBBHT fansare designed for installation into indus-trial buildings where there is a require-ment for the extraction of fire smoke.

They are suitable for continu-ous operation in clean air andnon dusty smoke to a maxi-

mum temperature of +200°C. Inemergency smoke extract situa-tions the range will operate at+400°C for 120 minutes and is CEcertified to F400 in compliancewith EN12101-3 by the Applus lab-oratories in Barcelona.

Construction• Dismountable cabinet in galvanized

steel sheet. Double inlet impeller

with forward curved blades in galva-

nized steel sheet.

• Belt coupling with self aligning sup-

ports, outside the airflow. Height ad-

justable motor support plate for the

tensioning of the belt. Belt coupling

protected by a guard in galvanized

sheet.

Motor• Asynchronous three-phase motor, IP55 mechanical protection, insula tion class F, single or double polarity, suitable for S1 service, mounting type B3, construction according to IEC/EEC (UNEL MEC).• Arrangement 9: belt coupling with motor placed on the upper panel.• Arrangement 12: belt coupling with motor placed aside on a common base plate (only for motors above 7.5kW).

Also available• Model with 2 Pole motor
