Efficient glass reinforced plastic fans

Ideally suited for tunnel ventilation, the GRP range is among the most durable and reliable wall exhaust fans Big Dutchman has to offer. These fans tick all the 3 most important aspects of proper ventilation – including air performance, fan efficiency and air flow ratio. 

Durability is also a key feature of the GRP fan with the corrosion resistant fibre glass casing, along with airfoil glassfibre-reinforced impellers. Long service life is also ensured with stainless steel and aluminium based internal hardware combined with UV coating protection on both sides of the fan.
