Abstract

A compressed air purification plant, for air respiration, esp. for divers, fire fighting units etc. consisting of a series of individual chambers connected in a particular sequence and containing silica gel, Hopcalite and chemical adsorber, is constructed with separate vessels containing the silica gel, hopcalite and chemical adsorber, and interconnected by pipes; the pipe connecting the silica gel vessel to the Hopcalite vessel contains an air preheater and a non-return valve. the advantage of the arrangement is that improved purification is achieved in the last, adsorbing stage.
