The question of proper airflow in an industrial space is underestimated by many people. Heat, dust, and fumes can quickly influence the overall operation of the business as well as employees’ health and well-being. And choosing between two options that look quite similar from the beginning causes certain difficulties. Actually, there is nothing surprising about it because such a decision depends on the compatibility of the ventilation system and the building itself.

Learning more about the wall mounted industrial exhaust fan and roof exhaust fan differences will help make the choice and use them in your business efficiently.

Features of Wall Mounted Industrial Exhaust Fans

Wall mounted exhaust fans are installed in exterior walls and remove hot and contaminated air from the premises. They create constant airflow and replace the indoor air with fresh air.

But have you ever thought why exactly these fans are so widely used? There are some reasons for that. 

  • Firstly, such fans offer the possibility of targeted ventilation. Thus, you can install them in any area where a lot of heat and fumes accumulate quickly.
  • Secondly, this type of ventilation is perfect for small spaces or specific zones that require the improvement of airflow.

Installation is simpler and more cost-effective compared to roof fans because they do not need any big construction changes.

Features of Roof Exhaust Fans

Roof exhaust fans are installed on the rooftop of the building and remove warm air directly upwards. As you understand, such a design is convenient because of the natural tendency of the air flow and therefore provides efficient management of air all over the facility.

Such ventilation systems are used in warehouses and big industrial units where the ventilation should cover the whole building.

We know that managing the air flow all over the facility is a quite a complicated task. However, such a design simplifies this process and makes the ventilation system effective for long-term usage.

Main Difference Between the Two

The key difference between these systems lies in the principle of their functioning.

  • So, while the fans on the walls create local airflow in particular zones, the fans on the rooftop regulate the air movement all over the facility.
  • Moreover, wall mounted fans are easier to install and maintain. That is why they are convenient for businesses with a limited budget.
  • In turn, roof exhaust fans require more preparation work before the installation but offer wider coverage of the space.
  • Besides, noise levels also differ. Usually, roof fans are quieter inside the facility than wall mounted ones.

Therefore, it is necessary to decide which kind of ventilation your space requires.

Which Ventilation Will Be More Effective in Your Business?

The choice between two options depends on the layout of the facility, airflow needs, and your everyday operations.

For instance, wall mounted fans are more preferable in case of smaller facilities or concentrated heat and fumes.

They offer quick ventilation and are easier to install.

Roof exhaust fans are suitable in cases of big warehouses or manufacturing plants where large volumes of air have to be removed.

Why Professional Consultation is Important?

Making a choice of the ventilation system requires taking into account a number of factors and making decisions very carefully.

Professional consultation can help avoid mistakes and make sure that the ventilation system works effectively over a long period of time.

Conclusion

Both kinds of exhaust fans offer useful features for the ventilation of the facility. However, the choice depends on the way of using the space, airflow distribution and long-term goals.

While wall mounted industrial exhaust fans provide targeted and cost-effective solutions, roof exhaust fans provide wider ventilation.
