About Us
In 1928, The London Fan and Motor Company was formed by Mr. G. H. Webber and has been owned since by
the Webber family. During the early years the company began to manufacture industrial propeller fans and
electric motors under the trade name Breeza Fan and moved from Charlotte Street in the West End of London
to a larger factory in Alfred Place off Tottenham Court Road.
After the Second World War the company moved to Park Road, North Acton and then to the present premises in
1965. The post-war years saw the development of the company into a wide range of ventilating equipment and
industrial fans brought about mainly by the take-over of a number of other businesses in the fan trade, one of
which became Breezax Impellers Ltd. The company discontinued the manufacture of electric motors and its
name changed to The London Fan Company Ltd.
Having built a reputation for quality fan manufacture and innovative design, the company continues to expand
its manufacturing base to ensure worldwide availability of industrial fans and Breezax impellers under the
leadership of Andrew Webber. With investment in the development of new products, the company looks to a
successful future in an evolving global market.
In 1990, The London Fan Company established Breeza Fan in USA.
In 2001, Breezax Technology Pte Ltd established in Singapore which is representative of London Fan
Company products and Breezax Impellers in United Kingdom for Asia Pacific Region.
In 2018, Breeze Industrial Ventilation Joint Stock Company was established in Vietnam. We are authorized
from Breezax Technology Pte Ltd to import, manufacture/assemble and distribute Breeze Fan in Vietnam for 04
countries in Southeast Asia.
Territory:
Ÿ Socialist Republic of Vietnam,

Description

Axial fans offer you a complete range of fan system and wide options of accessories such as impellers and
hubs to meet all kinds of applications and demands. The impeller of axial fans offer high efficiency up to 80%
or even higher.

Advanced Design of Straightening Stator Vanes and Ogive for Axial impellers:
With world’s leading Computational Fluid Design (CFD), axial fan has developed advanced straightening
stator vanes and ogives for axial impellers. As the figur shows, with straightening stator vanes and ogive,
turbulence in front of impeller has been greatly reduced, airflow becomes more stable and the efficacy can be
improved up to 8%.

Notes:

As we cam see the amount of air movement induced by the thrust of the Jet Fan is many times the airflow
through the Jet Fan. This property enables the Jet Fan to replace conventional ducting in car park ventilation
though the main exhaust/fresh air fans remain.

Figure B: Side view of velocity profile of jet fan

The velocity profile of a Jet Fan can be numerically determined through Computational Fluid Dynamic (CFD)
analysis with the boundary conditions (proximity to floor slab, beam obstruction, etc) as stated. The velocity
profile of the most common 450mm diameter axial type of Jet Fan, operating at high speed under a ceiling slab is
as follow:

1.0m/s 0.5m/s 0.3m/s

Jet Fan

This Jet Fan typically produces a thrust force of 84N (Newtons) at high speed. Some modification to impeller
blade or its pitch angle can result in higher thrust force but at the expense of higher noise level and power
consumption. The higher the thrust force, the further and wider the air throw of Jet Fan can reach and thus
covering a larger floor area. Larger fan has higher thrust but designer of car park ventilation system has to
consider the size of fan as well as the head room requirement by relevant authorities. It is also favorable to keep
minimum number of fans in a system as life safety feature in emergency mode.
The figure below shows a car park space of around 2,600m2 that is ventilated by Jet Fan system. It illustrates

The Jet Fan are operating at high speed (fire mode) and a car in the middle in on fire. The main exhaust fans are
at the top right hand corner while the main supply air fans are at the left hand side. The bulk airflow created by the
main fans as well as the airflow induced by the Jet Fans will direct the smoke towards the exhaust point of the
system. The induced airflow also effectively helps to dilute the smoke & heat produced by the fire to keep toxicity
and temperature from reaching dangerous level.
The cross sectional view of Jet Fan installation shows its great range of air throw at fire mode if no or minimal
obstruction to airflow by beam or other M&E services exists:

If you know the Litres/second (L/s): changes per hour for that room. Always use the
higher limit.
L/s x 3.6 = m³/hr. (e.g. 25 L/s x 3.6 = 90m³/hr).
Ÿ The result is the total performance required in cubic
metres per hour.
If you know the Cubic Metres/hour (m³/hr):
