Spirax Sarco liquid drain traps
provide automatic and continuous drain operation in order to increase
system efficiency. Many industrial processes involve the removal of
a liquid from a pressurized gas. The most common example is
compressed air. Atmospheric air always contains some water vapor. When the
air is compressed and cooled, it can hold less moisture. The excess water
vapor condenses to form liquid water. This water is harmful to the
distribution system and the pneumatic equipment. A liquid drain trap is
used to drain off the water while preventing the escape of compressed air.
