Disclosed is a two or three phase separator including a centrifugal separator, a demister (if a three phase separator), and a filter contained within a housing. The filter uses an outside-in flow principle. The filter includes an inner layer or a center core that defines a hollow interior. An outer layer is positioned adjacent and surrounding the inner layer. The outer layer includes a re-enforcement layer, a first particle filter layer, a coalescer layer, and a second particle filter layer. An access cover of the separator includes a cover plug, an actuator cam, a plurality of idler cam plates, and a plurality of mechanisms. The access cover cooperates with an opening and an annular groove in the housing to close off and seal the separator.

The invention claimed is: 1. 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. 2. The gas separator according to claim 1, further comprising a reinforcement layer disposed about the outer polymeric particle filter layer and wherein the reinforcement layer is made of mesh screen. 3. The gas separator according to claim 1, wherein the outer polymeric particle filter layer is made of spun bonded polyester. 4. The gas separator according to claim 1, wherein the inner polymeric particle filter layer is made of spun bonded polyester. 5. The gas separator according to claim 1, wherein the inner polymeric layer is made of sintered polyethylene. 6. The separator according to claim 1, wherein the filter is cylindrically shaped, includes opposed ends, and includes a pair of end caps positioned to cover the opposed ends of the filter. 7. A separator for gas under pressure, comprising: a housing comprising a gas inlet, a gas outlet, and an opening and an internal annular groove adjacent the opening; a filter disposed in the housing and 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; and an access cover, wherein the access cover includes: a cover plug configured to fit within the opening; an actuator cam positioned adjacent the cover plug; a plurality of idler cam plates surrounding the actuator cam, each of the plurality of idler cam plates pivotably connected to the plug cover and including exterior edges configured to cooperate with the annular groove; and a plurality of mechanisms, each of the plurality of mechanisms attached to the actuator cam and one of the plurality of idler cam plates, wherein when the cover plug is fitted within the opening, rotation of the actuator cam in a first direction or a second direction causes each of the plurality of mechanisms to push or pull, respectively, each of the plurality of idler cam plates, thereby pivoting the plurality of idler cam plates such that the exterior edges engage or disengage with the annular groove, respectively. 8. A method for filtering gas under pressure in a two or three stage separator, comprising the steps of removing moisture from the gas with an optional centrifugal separator, and removing dust, particulate material, and additional moisture from the gas by passing the gas from the outside of a filter to an inside of the filter, wherein the filter includes an inner polymeric layer and a pleated outer layer disposed immediately about the inner polymeric layer, the pleated outer layer comprising 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 inner polymeric layer safeguards against passing droplets of liquid to a hollow interior of the filter defined by the inner polymeric layer. 9. The method for filtering gas according to claim 8, further including the steps of sequentially: passing the gas through the outer polymeric particle filter layer, passing the gas through the middle coalescer layer, passing the gas through the inner polymeric particle filter layer, passing the gas through the inner polymeric layer, and passing the gas through the hollow interior of the filter. 10. The gas separator according to claim 1, wherein the outer layer is vertically pleated. 11. The gas separator according to claim 1 wherein the filter provides approximately 20-80 ft2 of surface area. 12. The gas separator according to claim 1, wherein the matrix of micro-borosilicate glass comprising the coalescer layer is a non-wicking glass structure mat adapted to remove liquid in compressed gas. 13. The gas separator according to claim 6, wherein the end caps are made of polyurethane. 14. The gas separator according to claim 1 further comprising a centrifugal separator connected to the gas inlet for removing moisture from the gas entering the gas separator from the gas inlet, and wherein the filter is disposed downstream of the centrifugal separator.
