Visionar designs and manufactures test benches for fans with automatic or semi-automatic measurement of:

  • Flow rate
  • Pressure (total and static)
  • Rpm
  • Electrical power, voltage and current
  • Measurement of the torque absorbed by the fan (with calculation of the fluid dynamic efficiency)
  • Constant rpm and constant duty cycle tests (for brushless motors)
  • Standardized measurements in accordance with the ISO5801 standard
  • Single-phase 120-230V, three-phase 230-500V, 50 and 60Hz adjustable power supply
  • Connection with proprietary performance simulation software


For specific applications for fans for heating, additional modules have been developed capable of simulating the gas flow rates entering the ventilation system in order to reproduce the operation of the air-gas systems in the boiler.

Tests can be performed automatically or manually.

The range of test benches that can be manufactured allows covering a range of products ranging from 100 to 100,000 m3/h.
