Two-stage axial fan

Axial fans are connected in series in plants to increase the pressure. In theory, connecting two fans in series doubles the pressure increase.

• investigate two-stage axial fan
• two identical single-stage fans in series configuration or individual operation
• fans both with variable speed via frequency converter
• flow-optimised nozzle and flow straightener for smooth, low-turbulence flow
• air flow in the pipe section can be adjusted via throttle valve
• optional pipe bend at the outlet for flow deflection
• measuring device with three-hole probe for determining the differential pressure on rotor and guide vane system
• sensors for pressure and temperature upstream and downstream of each fan
• volumetric flow rate measured via inlet nozzle
• software for data acquisition via USB under Windows 11
