For all our fume cupboards we use direct drive centrifugal extraction fans manufactured in Europe. These fans are moulded polypropylene and chosen to match the fume cupboard to provide efficient extraction. Maintenance is minimal as there are no belts to tighten or inspect.
Fan speeds are controlled using high quality inverter drives that are matched to the fan motor. These drives can be used to set the required fan speed for each individual installation, or to provide a continuously variable airflow based on sash position.
