Air Valve Set | Biolan 220 Eco Composter

The Biolan Air Valve Set is a purpose-made replacement part for the 220 Eco Composter, designed to manage how fresh air enters the unit. By allowing controlled airflow into the compost chamber, the valve helps maintain the conditions needed for an active, healthy composting process. Good ventilation is essential for keeping the contents aerated and preventing excess moisture from building up. When the original valve becomes worn or blocked, airflow can be reduced, affecting performance. Fitting a new inlet valve restores the composter’s ability to draw in air naturally, supporting odour reduction and consistent breakdown of material. Manufactured from robust, weatherproof materials, this inlet valve is built to withstand year-round outdoor use and installs easily as a direct replacement for the existing component on the Biolan 220 Eco Composter.
