Passive Vent
Passive Ventilation Vents are used as a passive condensation, mould, humidity and moisture control solution. They work either on there own, on in conjunction with a positive ventilation system (PIV), a constant negative ventilation system (CMEV), additional background ventilation or matched with a mechanical extract system. Simply put, they aid the movement of air in or out of a building.
Condensation, moisture, humidity and air movement is regulated by adjusting the iris type shutter inside the passive vent. A small slider at the bottom of the grille allows adjustment from fully open to fully closed. A pull cord is also provided if the vent is mounted at a high level.
When using as a fresh air intake vent, the internal membrane filter acts as a barrier against noise, dust and airborne particles entering your kitchen, wet rooms, habitable and living areas.
