The fan is designed for extracting air from small and medium sized rooms such as bathrooms, showers, kitchens, greenhouses, cinemas, cottages, shops and wherever you need high pressure and low noise at the same time.
The fan is designed for installation in rigid and flexible ducts. The fan is designed for both vertical and horizontal placement. This type is suitable for installation in wet environments due to its construction in durable ABS plastic. Mounting brackets are supplied with the fan.
