The Multiple Extract Ventilation category offers specialised configurations for extracting stale or moist air from more than one room simultaneously. These are ideal when you need a multi-room extract fan system, centralised extraction system, or multiple extractor fan units that serve bathrooms, kitchens or utility rooms through one central fan. Whether for a new build or renovation, these systems allow efficient airflow across multiple duct runs while reducing noise and energy use. Here are the types of multiple extract systems available:

• Multi-point extraction fans – one powerful fan unit connected to several ducts leading to different rooms, creating centralised ventilation extract system.
• Multi-room extract fan systems – designed to serve two, three or more wet rooms (bathroom, kitchen, en-suite) from a single unit.
• Combined extraction systems – kits that include fan, ducting and grilles to simplify installation for several extraction points.
• Whole house extract ventilation units that allow simultaneous extraction in bathrooms, kitchens and utility rooms whilst maintaining quiet operation.

Many customers wonder “how to size a multi-room extract fan”, “noise levels in multiple extract systems” or “how to install central ventilation extract system properly”. The products here include performance ratings for airflow (e.g. l/s or m³/h), sound levels in dB, and compatibility with standard duct sizes. These features help ensure that the system meets both building regulations and user comfort expectations. Products in this range often include optional accessories like duct kits, grilles, back-draught dampers and condensation traps to ensure that each branch remains efficient and the central fan maintains balance. For installers and DIY users alike, a well-designed multiple extract configuration ensures no room is under-ventilated, keeping moisture, odours and mould at bay. Choose a multiple extract system when you have more than one wet room, or where multiple humidity sources exist in the property. A centralised extraction system or multi extract fan with ducting kit delivers reliable performance, improved indoor air quality and more efficient ventilation overall.
