The importance of good ventilation and healthy air

2 minutes reading - published on August 18, 2020

Nowadays, there is a lot of talk about the importance of proper ventilation in relation to the risk of corona infections. According to researchers, there is a risk of airborne corona contamination in poorly ventilated areas. It is therefore important to continuously exchange indoor air and to properly ventilate it.

It is advisable to take into account, among others, a number of measures regarding ventilation (Based on guidelines of the Federation of European Heating, Ventilation & Air Conditioning Associations, REHVA).

  • Make sure there is sufficient fresh air supply, especially in areas where the average occupancy rate is somewhat higher on average. Meanwhile, make use of both mechanical ventilation systems and the existing regular airing with windows.
  • Ventilate more than usual for the time being. Normally, a fresh air supply of 30 to 40 m3/h per person is maintained, but in corona times it is advisable to maintain, for example, 60 m3/h per person as the absolute lower limit.
  • Turn off central and decentral recirculation (if present) and ventilate using only outside air. It is not advisable to disperse extracted air (or part of it) in other places throughout the building. Also pay attention to the air conditioning system. Many air conditioners only circulate.
  • If there are no mechanical ventilation systems or if insufficient capacity is available, instruct building users to open windows more frequently than usual.

It is often difficult for restaurants, bars, gyms, halls, etc. to adjust things within the current systems. Thanks to their flexible nature, fans are often easy to use in various applications as extra support. Our wide range of fans can contribute to:

  • Good ventilation for comfort and well-being.
  • Good air exchange.

Specific recommendations may differ per industry/company/hall. In buildings such as schools, offices and restaurants, it is a good idea to translate the advice to your specific situation and to make smart choices about what to do and what not to do.
