Passive Wall Vent Condensation Mould & Humidity Control Background Positive & Negative Air Ventilator with Filter & Draft Excluder Kit

  • £38.00

Blauberg Passive Ventilation Vent Kits 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, 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 as 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 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.

When used as part of a central positive ventilation pressure system, especially in rooms that have high levels of dirty humid air such as bathrooms, shower, kitchens and utility rooms, adjustment can be made to increase airflow through the passive vent by simply opening the iris shutter. This is particularly effective for rooms with damp, condensation and mould problems.

Supplied in a easy to fit kit that consists of the internal passive wall vent (also available separately), telescopic wall duct sleeve, external white cowl vent, screws and sealing sponge.

  • For use in 100mm, 4" dia walls where fresh air intake or extract is passively required.
  • Anti draught, washable filter vapour permeable membrane included.
  • Adjustable iris shutter to control airflow and possible cold spots.
  • Telescopic wall sleeve to fit walls up to 500mm thick.
  • Cowled external wall grille finished in UV protected white.
