Never suffer from moisture problems again! Discover our Moisture solutions

Ventilation is the process of removing polluted air and bringing in fresh, clean air. This is vital to prevent various long-term problems. An effective approach to this is the use of mechanical ventilation. But what exactly does this entail? In what ways does it help combat moisture problems? And how can mechanical ventilation contribute to the fight against corona virus? All your questions are answered in this article.

Why is proper ventilation important?

The average Fleming spends most of his or her time indoors. Nevertheless, we note that indoor air quality is often significantly less than outdoors. This is often true of basements, where ventilation is generally generally challenging. This brings with it all sorts of negative consequences:

  • Without proper ventilation, all kinds of moisture problems can occur. Especially problems like condensation moisture are very simple to solve with ventilation. And do you solve condensation moisture? Then you can immediately do something against black mold.
  • Poor ventilation can also cause a variety of health problems.
  • Damp rooms are also harder to heat, so ventilating also helps you bring down that energy bill.
  • In addition to preventing and solving moisture problems, ventilation is also very good for purifying the air in your home, making the air healthier and more pleasant to live in.

So thoroughly ventilating your home has only advantages.

This is how you ventilate: the difference between natural and mechanical ventilation?

As already stated, through ventilation you remove polluted air and bring in fresh, clean air. With natural ventilation, this supply and removal occurs naturally. Grids embedded in the walls allow polluted air to go out while fresh air comes in through another grid. Or you open a window. That, too, is ventilation.

Still, natural ventilation is not always a good idea. Especially in well-insulated houses, this can be difficult, because everything was done there to keep the warm air in. Also, many people leave the ventilation closed in winter to keep out the cold air. At that time there is not even ventilation anymore.

There is also a big disadvantage to natural ventilation: you can't (or at least very difficult) regulate the supply and return of air, in winter cold air comes in, which makes your energy bill skyrocket.

With mechanical ventilation, these tricky points fall away and you can control the extraction and/or supply of air in a partially or fully mechanical way. Three different combinations are possible.

Mechanical ventilation

The different types of mechanical ventilation

Mechanical ventilation systems are divided into types from A to D. Ventilation system type A is natural ventilation, so we won't expand on that. Ventilation system type B is mechanical ventilation, but this form is rarely used in homes. We briefly review the details of ventilation systems type C and D.

Ventilation system type C(+)

Mechanical ventilation often refers to ventilation system C. This system is partly mechanical: the supply of air is natural, but its removal is mechanical. Two types can be distinguished in this:

  • In a type C mechanical ventilation system, that exhaust of air occurs continuously.
  • With a Type C+ ventilation system, the mechanical component is a whole lot smarter, and will exhaust air based on the CO² level or humidity in the room.

Ventilation system type D

Type D mechanical ventilation goes one step further. Here, both supply and exhaust are fully mechanical. There are several additional options, such as choosing a heat exchanger to save more energy. There is also the option of filtering for pollen and dust, which is especially beneficial for people with allergies.

With this type of mechanical ventilation, also known as balanced ventilation, the supply and return of air remains constantly balanced.

Which mechanical ventilation system is the best choice?

Now that you know the difference between mechanical ventilation type C and type D, let's briefly list the pros and cons.

  • Type C is the more cost-effective option of the two, since only one fan is needed, more specifically for exhaust control. A Type D fan system typically consumes more energy, given that it supports two fans.
  • Nevertheless, using a heat exchanger in balanced ventilation can help save energy. With Type C, more energy is lost in heating the colder air supply.
  • Type D is distinguished by filtering the outside air for pollen and particulate matter. This results in improved air quality, allowing people with allergies to breathe more comfortably.

Both mechanical ventilation systems help against moisture problems anyway. If you ventilate properly, condensation moisture no longer has a chance. It only benefits your health.

We take on viruses

You can also have something else built into the balance ventilation: the GPS-FC24-AC, an ionization system. Such an ionization system sends electrons into the air that cling to particulate matter, pollen, but also germs such as those from the coronavirus. After a 60-minute exposure, covid-19 particles had decreased by as much as 90%.

This is one of the products officially approved by the Federal Public Health Service to be useful in the fight against coronavirus. Is the product not on that list? Then it is forbidden to be sold in Belgium.
