What is basement ventilation?
Floor ventilation is the activity of exchanging and circulating air between the inside of the basement and the outside. They help to regulate the air, make the air airy, provide oxygen to ensure human activities, and reduce CO2 emissions from vehicles.
Why is it necessary to install a basement ventilation system?
As the name suggests, basements are often the location below, where there is little natural air circulation. They gather a lot of exhaust fumes from vehicles, along with the growth of various molds. In addition, basements are often used as warehouses, storing many goods.
Along with the fact that the basement is often affected by the ground, causing humidity. Therefore, if there is no ventilation, it is easy for mold to grow and make the environment inside the basement stuffy and stuffy. And this atmosphere can be harmful to human health.
Therefore, installing a basement ventilation system is extremely necessary and important. This will help circulate oxygen as well as eliminate toxic polluted air.

Basement Ventilation Methods
Basement ventilation is divided into 2 types as follows:
- Natural Basement Ventilation
This method uses natural air currents from outside to inside. Helps circulate air, avoiding stagnant air inside the basement. With a very simple natural method, people often design ventilation doors, air intake windows that can be opened and closed. Air currents from outside can go inside and vice versa.
This natural method is quite cost-effective. However, if you only use this method, you will not achieve the desired results. Usually, you need to combine both natural and mechanical methods.
- Mechanical ventilation
Mechanical ventilation is a method that uses mechanics to create air flow. They use industrial exhaust fans and duct systems, air vents, etc. to help remove toxic gases and mold from the basement to the outside. One-way ventilation helps to take fresh air from the outside and blow it back inside.
This method is an effective method to help clean the air, remove moldy moisture, odorous and toxic gases. It helps the basement become clean, airy and ensures human health and activities inside the basement.

How basement ventilation system works
The operating principle of the basement ventilation system is quite simple. As mentioned above, they have a 2-way function. One way sucks air out and one way blows in. This sucking and blowing is done by the operation of industrial exhaust fans and basement ventilation fans.
Normally, people can use axial fans, centrifugal fans or jet fans to perform this task. The suction and blowing process takes place continuously, helping the basement to always be in the most airy state. The exhaust fan has the function of sucking dust, moisture, and toxic gases generated in the basement and bringing them out through the air duct. When the suction process occurs, the basement is a closed space, leading to a pressure difference.
From there, the outside air will be sucked in to balance. In this way, people often combine natural ventilation and mechanical ventilation to achieve the highest efficiency.
Steps to design a ventilation system for the basement
To achieve the highest efficiency in basement ventilation systems, it is necessary to analyze and design the most suitable basement ventilation system.
Here are 4 steps to design a ventilation system for your basement.
- Step 1: Survey the terrain
Conducting a survey is indispensable for each system. The implementing unit needs to carefully study the structure such as area, height, infrastructure system... to have a suitable installation plan.
- Step 2: System design, installation location
After having an implementation plan, it is necessary to design the overall system. Show the expected installation location of ventilation equipment, air pipes, etc.
- Step 3: Calculate air flow and pressure
Based on the parameters and installation location, it is necessary to calculate the air flow and pressure loss. This step is very important because it affects the efficiency of the system. In addition to the flow and pressure, it is necessary to calculate in detail the number of inlet and outlet, air outlet, etc.
- Step 4: Choose the right device
Based on the calculated parameters, choose the appropriate equipment to ensure those criteria. Each type of industrial fan product often has different parameters. Therefore, when installing, it is necessary to choose the right equipment by carefully researching and reading the technical specifications of each product type.
