Ventient Wall Vent is precision manufactured AES plastic wall vent 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 Wall Vent 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 Wall Vent is installed into a framed wall in accordance with details on page 2. This wall vent can also be used in floor applications protected by a cover grill.
Where it is not possible to meet the code requirements for natural ventilation, or where the design preference is for a specific air change rate and 24 hour provision of fresh outside air without leaving windows open, Ventient, in conjunction with low energy, mechanical extract ventilation can provide or contribute to supply ventilation as required when calculated in accordance with AS1668.2.
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 Wall Vent could be an acceptable permanent natural ventilation opening as required in Clause 2.3.
Install Proctor Ventient Wall Vent with shape memory alloy thermal actuator in accordance with the user guide.
