The Brookvent BTP EC Duct series fans are the perfect solution when ventilation systems require relatively high compression, a strong air stream, and low noise levels. This makes them perfect for utilisation in ventilation installations in residential buildings, collective housing, and public utility buildings in particular. Their compact dimensions make them perfect for limited spaces – they’re dedicated for ventilation ducts of 100mm, 125mm, 150/160mm, 200mm, and 250mm respectively.
