FILTERS PRESSURE DROPS
The following charts determine the pressure drops of the lters with dierent levels of fouling. From the chart on the left, bearing the air ow
rate (m³/h) in the axis of abscissae, move up from the concerned ow rate until you intersect the straight line corresponding to the unit size. At
this point, tracing a straight line parallel to the axis of abscissae intersect one of the three curves shown on the right chart each representing
the clogging degree of the lter as follows:
curve 1: lter clean
curve 2: lter clogged at 25%
curve 3: lter clogged at 50%
To determine the value corresponding to the lter pressure drop, trace a straight line until the axis of abscissae.
