Since the year 2000 studies came available which proved the significant effect of air quality levels in the whole spectrum of air treatments. Beginning by decreased infections & use of antibiotics, reduced sick leave and ending at increased productivity.
The amount of virusses emitted will initially be 100% droplet and changes into aersols and surface sedimentation.
Over time the infection risk will also change from droplets to aersols and smear and due to natural inactivation like dehydration of the virus, after a few hours the total risk will also reduce. An increased RH% would prevent the droplets to become aerosols, but would also increase sedimentation.
How can we reduce the risk
Increase the Inactivation rate by means of adding active inactivation to prevent aerosols to spread further and sedimentation creating smear infektion risk.
The major methods of active deactivation are discplacement of contaminantion by means of increasing the ventilation rate and diluting of contamination by means of for example pumping the air as much as possible through a deactivation machine.
Extra ventilation does cost extra energy and isn‘t always possible because most professional buildings do have a regulated HVAC system and even increasing the RH% is not that easy implemented.
A Virobuster Steribase 300 can do a six air change per hour in a 50m3 room, resulting of a deactivation of 90% of the initial airborne contaminants within 23 minutes.
That would mean a significant improvement of your office, conference room or in our example, a gym safety.
A Building Solution can be considered if the building consist of several spaces where specific (independent) processes are conducted.
For example if preparation, production and packaging all are conducted in (closed) individual spaces.
- Free blowing
- HVAC Intergration
- Safe positive pressure
- Safe dilution
If there is no clear “space structure” recognized, and all processes are somehow gathered in one or more spaces – then a process solution should be considered.
A Process Solution offers protection from the so called “Zero-Point” (Baking, Grilling, Cooking, Steaming, Smoking, Pasteurizing, etc.)
- Safe cooling
- Safe transport
- Safe packaging
- Safe Slicing
- Safe Filling
- Safe (tank) aeration
