Real-World Results and Client Testimonials
“We are extremely happy with the performance and comfort we receive since installing these Air Pear fans and would happily recommend them to other people needing to circulate air and increase thermal comfort.”
Keith Stevenson, Facilities Manager
SCEGGS Darlinghurst, NSW
“The Air Pears certainly have made a big difference and improved comfort during the various functions we have at the centre. Since installation, there have been no complaints about overheating and there is much appreciation of having the areas cooler.”
Peter Gay, Facilities Manager
Green Point Christian College, NSW
“The addition of fans has greatly improved the working environment for staff and students, and it is something that I and the TAS team appreciate.”
Paul Berecry, Stage 5 Grammar Coordinator
Pittwater House School, NSW
Understanding airflow patterns
Correct fan placement is crucial for maximising airflow distribution while adhering to safety standards.
Data provided by a large blade fan manufacturer and highlights how their airflow moves in summer cooling applications.
Open area airflow
The airflow moves from the fan toward the floor.
When airflow hits the floor, it moves outward in all directions.
The deflection of air off the floor is called a floor jet.
Enclosed area airflow
The floor jet radiates outward until it reaches the walls, which deflect the jet upward. After it hits the ceiling, the upward flow is directed inward to the low-pressure area above the fan, where it is then pulled down toward the floor.
This creates a convection-like air current that gathers momentum. Once this current is established, the fan begins to move air outside the current, escalating its cooling effects.
Multiple fan airflow
Where multiple fans are appropriately spaced, the expanding jets of adjacent fans meet to create a pressure zone. The pressure zone acts like a wall, causing each fan to behave like a single enclosed fan.
Typically, a single fan’s performance will increase when working in conjunction with other fans.
Airius airflow pattern
No exposed blades
This image of Airius Air Pear units in operation highlights how the airflow pattern is similar to that of an HVLS product. The key difference is that one uses large exposed blades and one does not.
Eventually, the Air Pear airflow pattern will start to rise back up to the roof again and continue recirculating, as does the HVLS fan airflow pattern. Airflow is achieved across the floor at 600 mm AFFL.
