Patent ID: 7332010

Claim:
A separator for gas under pressure, comprising: a housing comprising a gas inlet and a gas outlet; and a filter disposed in the housing downstream of the gas inlet and including an outer layer in direct fluid communication with the gas having passed through the gas inlet and an inner polymeric layer defining a hollow interior of the filter, wherein the outer layer is pleated and comprises an outer polymeric particle filter layer, a middle coalescer layer comprising a matrix of micro-borosilicate glass, and an inner polymeric particle filter layer, wherein the hollow interior defined by the inner polymeric layer is in direct fluid communication with the gas outlet, wherein the gas passes from an exterior of the filter to the hollow interior of the filter, and wherein the inner polymeric layer safeguards against passing droplets of liquid to the hollow interior, and wherein the inner polymeric layer is in direct contact with the inner polymeric particle filter layer.
