VEA 050


Teaching suggested applications*


  • Determination of the fan characteristics depending on the speed, of the suction and discharge pressures
  • Study of a centrifugal fan
  • Study of the QH curves of the fan
  • Using a column manometer for the pressure measurements.
  • Flow rate measurement with Pitot tube.
  • Measurement of the electrical power to the motor, efficiency determination.
  • Verification of Bernoulli's equation.
  • Highlighting of the aerodynamic lines.


The VEA 050 is a bench that allows experiments on the fundamentals of air flow. The experimental unit comprises a centrifugal fan with variable speed, allowing to generate different speeds of air flow. A fan output damper can be used to adjust the air flow rate allowing the study of the characteristic curve of the fan. When used in conjunction with the power measurement device, it is possible to determine the efficiency of the fan. It is possible to study the air velocity profile within the pipe using a Pitot tube and to position it at different heights in the duct through a metallic ruler.

The cylindrical inlet pipe may be replaced by a rectangular section duct having a hatch allowing to insert a layout in order to study the flow of air around the latter.

The robust design of this equipment makes it perfectly suited for school use.

Its anodized aluminum structure on wheels makes it very robust as well as a great flexibility of integration into your premises. The chassis is split into two parts with a connection by flexible sleeve.

The manufacture of this equipment meets the European machine directive
