Preventing viral transmission in HVAC systems – White Paper from FlaktGroup

Indoor Air Quality v1.

The current pandemic has, naturally, increased the focus on indoor air quality. The quality of the indoor environment is a combination of all elements of the ventilation system and to date, there has not been a well-documented SARS-CoV-2 (Covid-19) outbreak traced to aerosol transmission through a central supply and extract ventilation system.4

The spread of infections due to central mechanical supply and extract ventilation devices is, therefore, very unlikely. There are many academic studies underway to understand the transmission of the virus through particles suspended in the air and it makes sense that precautionary measures to reduce the possible spread of such particles in ventilation systems should be taken.

These precautions affect all elements of the ventilation system and our paper attempts to share best practice for practical measures that can be taken to minimise the risk of transmission.
