The separating action of senator largely depends upon the contact surface area necessary for impingement, which must be very distributed. Generally speaking, a higher free volume leads to lower pressure drop. In critical cases, it may be necessary to decide whether pressure drop or efficiency should be sacrificed. However we must eliminators allows the greatest possible efficiency at the lowest possible pressure drop.
