Cased Axial Fans - Three Phase

Cased Axial Fans - Three phase

The Helios HRFD three phase fan range are cased axial flow fans with drilled flanges for connecting to circular ducting. These are a popular choice for systems that require a high airflow and a moderate pressure. Suitable for indoor or outdoor use as they are IP55 and have a galvanised steel casing. These fans can be reversed to give approximately 70% volume in the opposite direction to the original flow. HRFD fans are three phase models / 400v / 50 Hz.
