Proctor Ventient Round Wall Vent (RWV)
Round wall vent with passive temperature sensing flow
The Ventient Round Wall Vent (RWV) is precision manufactured AES plastic vent for interior or exterior applications with passive temperature sensing flow control.
Improvements in construction create buildings that are more airtight than previously, with the result that infiltration or leakiness is no longer providing a pathway for make-up air for exhaust systems.
Although many building are complying with building code requirements by having sufficient operable windows, changing lifestyle patters, concerns about noise and security and generational differences mean that ventilation from open windows tends to be infrequent.
Unlike conventional systems such as operable windows or louvres, Proctor Ventient RWV can get on with the job of providing fresh air circulation regardless of occupancy.
As part of the total ventilation system Proctor Ventient can provide continuous ventilation to spaces even if they are unoccupied and is perfect for student accommodation, hotels, age care, healthcare and educational facilities.
Ventient is an ideal solution for residential buildings such as modern air tight homes and medium or high rise developments, as modern lifestyles mean that occupants are unable to mange purge ventilation and often return home to a stuffy environment.
The Ventient Round Wall Vent is installed into a masonry or timber frame wall as shown on page 2.
AS1668.2 draws to the attention of designers that increased air-tightness of modern buildings requires consideration of sources of make-up air. Make-up air drawn through gaps and service penetrations does not meet the requirements of Clause 2.3 within the standard and can lead to the loss of amenity in the enclosure.
Ventient SFV could be an acceptable permanent natural ventilation opening as required in Clause 2.3.
Install Proctor Round Wall Vent (RWV) with shape memory alloy thermal actuator in accordance with the user guide.

Notes
*Note that the degree of opening may not always reflect the exterior temperature, as this will periodically differ from the ambient temperature where the SMA actuator is located closer to the interior. There is also a lag in adjustment to sharp changes in temperature.
