Envirovent 100mm 4" In-Duct Fan with Timer

Domestic centrifugal in-duct extractor fans provide high-performance ventilation in a concealed format, ideal for homes with long or complex duct runs. Positioned within the ducting system, these fans are perfect for bathrooms, kitchens, and utility rooms where space is limited or a discreet appearance is preferred. Their centrifugal design ensures strong airflow even through bends and extended ductwork, making them superior to axial models in high-resistance applications. With quiet operation and reliable efficiency, they're well-suited to modern home ventilation needs.
