This specification covers adsorptive purification and dehydration equipment for removing solid contaminants and particulate and vaporous water and oil from shipboard high pressure air systems. The word dehydrator will be used to denote the entire complex of equipment throughout this specification.

Dehydrators shall be of the following classes, as specified (see 6.2).

Class I - 3000 pounds per square inch (lb/in²) gauge working pressure. Class II - 5000 lb/in² gauge working pressure.

The required capacity of the dehydrator shall be as specified (see 6.2). When practical, a unit with one of the following standard flow ratings should be selected.

(a) F-75 - 75 standard cubic feet per minute (ft³/min) minimum capacity.

(b) F-100 - 100 ft³/min minimum capacity.

(c) F-150 - 150 ft³/min minimum capacity.
