Trickle Ventilators

Passivent standard window and wall vents are designed to allow air to enter the building to provide the stated levels of background ventilation to meet the requirements of Building Regulations. Geometric free areas are shown for Scottish Building Regulations.

Passivent acoustic window and wall vents not only provide the stated levels of background ventilation, but also noise attenuation for buildings which may be
situated where external noise could pose a disturbance to the occupant.
