Ventient Trickle Breathe

Proctor Ventient Trickle Breathe (TB)

Glazed-in trickle vent

Product Description

The Ventient Trickle Breathe (TB) is precision manufactured aluminium glazed-in trickle vent that can be accommodated into a wide range of window frames.

Applications

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 TB 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.

Installation

The Ventient TB is installed into the glazing pocket of the frame, in accordance with the product installation guide.

Exhaust Make-up in Lieu of Supply

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.

General Exhaust Make-Up Air

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 TB could be an acceptable permanent natural ventilation opening as required in Clause 2.3.
