Each tubular fan is housed within a solid metal case that is lined with acoustic foam to dampen the sound of the fan motor as well as softening the noise made by air rushing through the unit. Isomax fans are a great choice for attaching to a carbon filter for use as an extractor as they experience a much smaller drop in airflow compared to other inline fans when the filter is attached. The two smaller models (6 and 8 inch) come with an additional 3 stage dimmer switch to reduce air flow and therefore noise if less air exchange is required.
