Ventient SCW-SH Trickle Vent

With wind dampening and passive temperature sensing flow

Product Description

The Ventient SCW-SH is precision manufactured aluminium trickle vent that can be accommodated into a wide range of curtain wall and window frames.

The Ventient passive shape memory technology, without electric power, sensors or human intervention, automatically controls ventilation flow dependent on ambient temperatures, optimising the benefits of passive ventilation. Ventient SCW-SH also incorporates a passive wind dampener to manage water ingress and drafts normally associated with high wind gusts.


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.

Athough many building are complying with building code requirements by having sufficient openable 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 SCW-SH 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 SCW-SH is installed into the Ventient SH  head, transom or sill in accordance with the  install guide. Installation is also possible into curtain wall or other custom designed window frames. The vent should be completely serviceable from the interior.
