Axial-flow fans differ from radial-flow (centrifugal fans mainly by the fact that for comparable sizes and speeds they convey a large volume of air against a low pressure. Fans are available for higher and lower pressure within both groups, overlapping at the top and bottom of the range.
In axial fan design, the motor is primarily located in the airflow and typically installed in walls or ducts. The motors of radial flow fans are generally mounted outside the airflow. All the delivery rates, static pressures and motor rating given in the following pages apply to a medium with a specific gravity of 1.2kg/m3. SASA metal industry Axial Flow Fans are a best buy for many industrial air moving jobs.
Generally, an axial fan costs considerably less than a quality centrifugal fan delivering the same volume and pressure. They cost less to install since they are lighter, requiring minimum structural support.
Direct drive Models means faster startup and the absence of V-belt drive and fan bearings lowers maintenance costs. ADJUSTAX AXIALS feature an adjustable pitch Axial fan blade wheel that permits matching your pressure/volume requirements exactly and lets you make adjustments to compensate for system changes. Adjusted capacities from 300 to 85,000 cfm and to 4” total pressure.
