The DV 270 (T 271) droplet separator is a vane type separator for vertical flow. The gas flow charged with liquid droplets is directed through separator chambers which are designed for maximum effect on the gas flow. As a result of this configuration, inertial forces act on the droplets. The droplets impinge onto the profiles, where they form a liquid film which is subsequently drained off as a result of gravity. V-shaped impressions on the separator plates ensure that the liquid is drained off in the correct manner, dropping back against the vertical gas stream into the sump.
