This 100mm silenced inline centrifugal fan is designed for applications requiring useful pressure performance with reduced breakout noise. A backward-curved centrifugal impeller delivers dependable airflow through ductwork, while the galvanised steel casing is lined with acoustic, flame-retardant material to absorb motor and airflow noise. The compact unit is suitable for continuous residential and light-commercial supply or extract ventilation, particularly where longer or more resistant duct runs are involved. Its inline format allows the fan to be installed remotely from the occupied space.
