Filters comprising knitted or woven wire or monofilaments of a range of durable materials are widely used in industrial applications for arresting particles which have become aspirated in gas streams. In general, the finer and more efficient this kind of filter is the less suitable it is for removing solids because it is more susceptible to blockage, but it is eminently well suited to arresting liquid spray droplets as long as the liquid formed by coalescence of the captured droplets can drain away freely. Liquid spray is almost bound to be formed in any gas-liquid contact device or any vessel in which gas or vapour is evolved from a boiling or frothing liquid (boilers, ...
