Product Overview

Product Overview

An axial roof fan is a roof-mounted ventilation fan that moves air along the fan axis and is commonly used for general exhaust and fresh-air movement where high airflow and straightforward roof installation are required.

The DWT supplier sheet lists a 100% copper motor, high-quality plate base and housing, aluminum plate cowl, and model sizes from DWT3# to DWT8# with airflow up to 30,000 m3/h.

It is a practical option for commercial and industrial ventilation projects such as hotels, offices, laboratories, factories, residences, and general roof exhaust supply across Saudi Arabia inquiries.
