Blauberg Passive Ventilation Vent Kits - Your Solution for Mold, Condensation, Humidity Control, and Air Replacement

Designed for 100mm (4") diameter walls, our Passive Wall Vent Condensation, Mould, and Humidity Control Ventilator not only effectively addresses mold, condensation, and humidity issues but also serves as a versatile solution for air replacement, enhancing indoor air quality.

Key Features:

  • Versatile Use: This ventilator is perfect for spaces requiring passive air exchange and can seamlessly replace trickle vents, significantly reducing mold, condensation, and humidity levels, creating a healthier living environment.

  • Efficient Filtration: With a washable, vapour-permeable membrane filter and an anti-draught design, it not only keeps out dust and airborne particles but also reduces the risk of mold growth, condensation, and excess humidity.

  • Adjustable Airflow: The iris-type shutter offers full control over airflow, allowing you to regulate ventilation with ease. Use the slider switch or pull cord for effortless adjustment, even when mounted at higher levels.

  • Multiple Applications: This ventilator works harmoniously with various ventilation systems, including positive ventilation (PIV), negative ventilation, background ventilation, or mechanical extract systems, ensuring effective moisture and mold control while replacing stale air.


Blauberg Passive Ventilation Vent Kits serve as a robust solution for passive condensation, mould, humidity, and moisture control. Whether used independently or in conjunction with other ventilation systems, these kits excel at reducing mold growth, condensation buildup, and excessive humidity levels, all while facilitating the circulation of fresh air in and out of your space.

The iris-type shutter inside the passive vent allows precise regulation of condensation, moisture, humidity, and air movement. Adjust the airflow effortlessly using the slider at the bottom of the grille or the provided pull cord, particularly useful for high-level installations.

When employed as a fresh air intake vent, the internal membrane filter acts as a protective barrier, preventing noise, dust, and airborne particles from entering your kitchen, wet rooms, and living areas, while simultaneously reducing the risk of mold, condensation, and humidity. Simultaneously, it replaces stale air, ensuring a continuous flow of fresh, healthy air.

For rooms prone to high levels of humid, dirty air, such as bathrooms, showers, kitchens, and utility rooms, the iris shutter can be opened to increase airflow through the passive vent, effectively combating humidity issues, mold growth, and providing much-needed air replacement.

Trust Blauberg for reliable passive ventilation solutions that enhance air quality, reduce mold, condensation, and humidity, and replace stale air, creating a healthier, more comfortable living or working environment. Achieve optimal comfort and well-being with our Passive Wall Vent Condensation, Mould, Humidity Control, and Air Replacement Ventilator.
