Air volume unit
Fan characteristic test:
According to AMCA 210-85 "Laboratory Methods of Testing Fans for Rating" test specification. Place the fan at the wind tunnel opening as shown in the sketch, the wind blows into the wind tunnel, the air volume and static pressure are tested at various measurement points in the flow field, and the measured data are compiled by the computer to draw the characteristic diagram and data.
It can be seen from this figure that the air volume of the fans in parallel is increased, but the static pressure is unchanged; if the system impedance is low, the parallel mode can be used.
※Our company does not recommend using fans in series.
