VEA113
Operating principle
The VEA 113 bench allows the study of a fan of a ventilation system. It is equipped with a centrifugal fan coupled to a
potentiometer for varying the rotational speed of the fan. It is possible to determine the characteristics depending on the speed
of the suction and discharge pressures at the fan. This bench will also measure the electrical power, determine the efficiency of
the fan, measure the pressure losses in the different driving positions using a water column multimanometer. It will also be
possible to draw the air velocity profile of the vein using a Pitot tube and put in evidence the streamlines. The suction pipe and
fan are disconnected. The axial fan test bench is delivered complete, instrumented.
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.
