If you are looking for an industrial ventilation system, you may be looking for electric-powered fans or blowers. But there are more economical and energy-efficient options in the long run. We are talking about natural ventilation solutions, which have several benefits and perform much better than conventional options.
These modern and intelligent alternatives are necessary to ensure the quality of life at work and the well-being of employees. This is because good air circulation contributes to productivity and the maintenance of appropriate levels of salubrity in the corporate space. produtividade e a manutenção de níveis apropriados de salubridade no espaço corporativo.
In this content, we will explain the reasons that justify this investment and present two industrial ventilation systems that will change the reality of your shed. Check it out!
Natural ventilation system: why choose natural solutions
The traditional industrial ventilation system features forced mechanisms, such as exhaust fans and fans. These systems generate accumulation of stale air, which is very harmful to the health of employees.
Natural ventilation solutions, in turn, work from the density difference between the warm air - which is inside the shed - and the cold air, which is outside. This divergence generates a circulating current that improves the quality of the air inside.
The result of this process is a workplace with more health and quality of life for employees. Since natural ventilation provides constant air renewal, the temperature in the shed will always remain pleasant, which avoids a number of problems caused by excessive heat, such as fatigue in the teams.
All this happens without any electricity costs. After all, natural ventilation solutions do not consume a single kw to operate. The maximum performance of this industrial ventilation system is due to the Venturi and chimney physical phenomena, responsible for the constant renewal that increases the air quality in the environment.
In other words, it is a wise investment for those seeking energy efficiency and sustainability in the industry. In addition, the well-being and health of employees will be guaranteed, which is also primordial for the consolidation of a positive image of the industry in the market.
Industrial ventilation and occupational safety: understand the relationship
As we have seen, natural ventilation solutions help maintain a healthy corporate environment. Therefore, we can say that, with this investment, the industry will be able to more easily adapt to the Occupational Safety norms.
An example are the norms that regulate exposure to heat and the concentration of dust and chemical agents in industrial warehouses, such as NR-15. Keeping the warehouse free of gases, vapors, solvents and other toxic substances is therefore essential to comply with legislation and, above all, to preserve the physical integrity of employees.
In this sense, natural ventilation systems are even more necessary. This is because, unlike air conditioners - which do not allow the exchange of air within the environment - natural systems remove all the stale air from inside the factory, also exhausting dust and any toxic particles suspended in the room.

Sistemas de ventilação natural que irão mudar a realidade do seu galpão
Before we talk about the most commonly used systems to enhance air renewal in industry, let's explain the main types of natural ventilation that exist:
Cross ventilation
It consists of using openings on opposite sides of the warehouse to allow the natural flow of air in the environment. Depending on the spatial configuration of the factory, this air flow can be either horizontal or vertical - in the case of buildings with more floors.
Single-sided ventilation
Single-sided ventilation considers only one opening on one side of the room, through which the air flow will be enhanced. The choice for this type of natural ventilation will depend on the layout of the shed, because in some cases this feature is more efficient than cross ventilation.
Gravity ventilation
This type of natural ventilation is the most efficient. It consists of creating a wind-driven airflow through an opening such as an industrial Venetian. Thus, the current crosses the shed and runs through the entire internal space, propelling the heated air to the top of the factory. This negative pressure that takes place on the roof takes the warm, stale air outside and keeps the internal temperature pleasant at all times.
Ventilation with lantern and industrial blinds
The two best-known natural gravity ventilation solutions are louvered and industrial shutters. Below we will explain how each one works.
1. lantern
The lantern works as a natural exhaust fan, boosting the exchange of internal air to keep the shed free of toxic particles. It is installed on the factory roof. As there are no moving parts and/or parts subject to wear, the solution requires no maintenance and can be installed easily. Among its other benefits, we can highlight
- More respiratory health for employees;
- More productive teams with more quality of life;
- Replenishment of oxygen levels and elimination of stale air;
- Electrical energy savings and sustainability for the industry.
2. Industrial blinds
Industrial blinds ensure permanent lighting and ventilation. They can be fixed or movable and have a manual or automated drive. The choice will depend on the needs of each project. As for the main advantages, we highlight thermal comfort and indoor air quality, due to constant renewal. In addition to these benefits, the blinds also provide:
- Energy efficiency for industry;
- Easy installation and zero noise emission;
- Uniform natural lighting with UV protection;
- Options of protective screens (mosquito netting and bird netting).
How do I know if the natural ventilation system will be efficient?
One of the ways to ensure an efficient industrial ventilation system is to choose suppliers who are experts in the market. Designers who work with innovative methodologies such as CFD (Computational Fluid Dynamic) will certainly design high performance natural ventilation systems. So this is also a good indicator of quality.
The MB Group, a reference in the segment of natural lighting and ventilation for 20 years, is a pioneer in the use of these intelligent methodologies to ensure maximum performance systems.
CFD, for example, is a computer simulation capable of proving the effectiveness of a system with louver and blind before taking it off the drawing board. Through this resource, it is possible to visualize how the air behaves in the shed, what the established current is, and thus define where the blinds and/or the louvers should be installed. Thus, the manager will have a high performance solution with guaranteed return.
