Take measurements at 4 dierent points of the hose perimeter as shown in the following picture, and also take a
measurement at the center of the hose. Always take measurements close to the end of the hose, where it
connects to the printer air exhaust kit, and make sure the anemometer wheel is perpendicular to the direction of
the air ow.
For each of the measurement points, take 5 dierent measurements, nd the minimum and maximum values,
and calculate their average. Finally, calculate the average of all 5 measurement points. Results should be within
specications according to the numbers provided previously. If one of the 5 measurement points is much lower
than the other 4, this could indicate a problem with the exhaust hoses. For example, that the hose is not straight
and bends at some point along its path.
Important airow notes
● Too much or too little aspiration ow and/or pressure may inuence the printing process, aecting the part
quality. Too little aspiration may lead to lack of temperature control and health issues with some printing
materials. See materials safety data sheet for more details. Too much aspiration produces a waste of
conditioned air from the room. Unbalanced aspiration may cause problems with the temperature of the
material.
● Air recirculation in air-conditioning systems may cause health issues with some printing materials. The
extracted air should be eliminated and clean air should be introduced into the room to replace it.
