The Biolan Rooftop Ventilator is a non-electric, wind-powered ventilation system designed to enhance airflow in composting toilets, dry toilet systems and buildings (eg. garden sheds).
By naturally drawing air upwards, it removes excess moisture, gases, and odours, preventing the buildup of condensation and improving overall system efficiency. With improved ventilation, composting toilets maintain an optimal aerobic environment, ensuring faster decomposition and a hygienic, low-maintenance waste system.
Constructed from durable, weather-resistant materials, the Biolan Rooftop Ventilator is built to withstand varying outdoor conditions, offering long-lasting performance without the need for electricity. Its lightweight yet sturdy design allows for easy installation on standard ventilation pipes, making it an ideal choice for off-grid homes, cabins, glamping sites, and remote properties.
