Fire fighting system Exhaust Fans

Exhaust Fans

Exastas refers to fans that pull and release air rather than blowing into the environment

The kitchen hood is a simple example of an exterior fan

We have two types of Extras fan

Exhaust fans that circulate air and Exhaust fans that remove air

In the first case the air is filtered and filtered and returned to the environment again

Exastas are very powerful industrial spaces with a suction power of 1400CFM

Types of Exhaust Fans

Ceiling - Axial - Utility

Extruded fans have either axial or centrifugal fans

These fans are usually one-way and forward

For all buildings with 3 floors or more of basement or buildings with underground more than 500 square meters, design and implementation of parking ventilation or exhaustion is essential because the accumulation and spread of smoke in these locations is extremely damaging

The following are essential when designing an exhaust fan

 The first basement, whether or not to have a parking lot, is numbered, but the last basement is only counted if it has a parking lot

All fans and related equipment shall be capable of withstand hot gases with a temperature of 300 ° C for at least 1 hour

 Inlet and outlet ducts shall be at least 3 meters apart from the chimneys and fans

All fittings, ducts and ... Exterior fan system in the building must be resistant to temperature 800 ° C

You must seek the help of a design engineer to choose an exterior fan that meets the needs of the building

In short to determine a suitable fan exhaust

 Type of fan

Aeration Capacity /CFM

STATIC PRESSURE

Produced Sound /SONES

Exterior fans are designed and manufactured in different models for different uses and locations, and must be selected for the most suitable and economical type of building or location

Exterior fans are installed in three common locations: roof - wall - channel

The main components of the fan are fixed in all installation positions, and only depending on the design and installation position, the fan housing is subject to change

Consultants - Designers and Engineers of Exast Fan Design Companies examine the structure of the building and visualize the air circulation in the building body, location and type of fans

The volume of the air exchange is also determined after the type of fan exast is determined

Enclosed or underground parking garages require ventilation to remove harmful vehicle emissions and other pollutants, while providing fresh air. Ventilation is also a requirement in the event of a fire to remove smoke and to provide a clear access for firefighters. Exhaust and supply fans are used in conjunction with ductwork to distribute air throughout the parking garage, providing a common system for both pollution and smoke control. Twin City Fan manufactures a complete line of axial flow fans designed for parking garage ventilation systems
