“To Prevent The Next Pandemic We Must Regulate Our Air, Like Food And Water” Scientists say. Scientists have finally woken up to what some of us in the HVAC industry have been saying for the past 20 -30 years. That said, I cannot agree more with Professor Lidia Morowska from QUT who is quoted in the paper as saying ... “Air filtration and disinfection will be needed” and “There needs to be a shift away from the perception that we cannot afford the cost of control”. In many bu
Here is a free event on Wednesday 17th March (Marvel Stadium - Melbourne) for anyone in the #HVAC (Heating Ventilation Air Conditioning) Health and safety or allied industries. This is for everyone concerned about the airborne spread of illness in buildings. Original Safe T Air will be at stand # 49. We look forward to seeing you there.

This arrived in my inbox this morning... Although simplified it does outline the issues of IAQ. It is really useful for consumers, Health and Safety people, and of course #HVAC ( Heating Ventilation Air Conditioning) and #HRV (Heat recovery ventilation) specialists. It's produced by the Building Engineering Services Association UK in association with #mitsubishielectric & #Farmwood UK Ltd https://www.thebesa.com/media/1409350/indoor_air_quality_guide_finel_1pp.pdf If the abov
Time for preventative maintenance on HVAC systems WHY?
* Shutting down HVAC systems and reducing airflow increases filter efficiency = increased level of bio-contaminants settling in filters ductwork and entire building envelope
* Bio-contaminants are food for bacteria and mould creating bad odour.
* Restored airflow blows the bio-contaminants around your building.
* Restored foot traffic grinds and throws up settled bio-contaminants in carpets. Ultrafine particles >PM1.5
This graphic came to my inbox, and I'd like to share it with you The last point in the Engineering column is so very important. Often air handling systems are the most neglected. Out of sight - Out of mind. Bringing fresh air into a large ducted system is not easy. #HVAC systems are designed to bring in only 20% fresh air this means 80% is re-circulated. Yes you are breathing the exhaled air of the person that you don't like down the hall. If a building has wall hung split s
The Nelson Mail (NZ) reported today that parts of The Millers Acre Centre, were closed in early May for urgent repair after four different locations in the building tested positive for the presence of Stachybotrys chartarum, a potentially toxic black mould. This was due to water ingress from the cladding. Nelson City Council acting group manager of community services Mark Preston-Thomas said the cladding system of the building, Insulated Concrete Form-work also known as Poly
