Measuring and adjusting the air flows of the ventilation unit

Measuring tubes Vallox 90 MV

The fixed air flow measuring tubes of the ventilation unit are located behind the name plate. The overall pressure of the supply and extract air ducts can be measured from measuring tubes with a differential pressure gauge. The pressure measurement results can be used to check the volume flow rate of each operating mode from the unit’s air volume table. The red measuring tube is on the pressure side and the black measuring tube is on the suction side of the fan.
