Abstract
A serviceable gas/liquid separator is provided. The gas/liquid separator has a cross-section with one long axis and one short axis, with an aspect ratio of at least 1.3. A preferred cross-section, is an elliptical cross-section. Assemblies in which the separator unit can be used, are provided. In addition methods of use and construction are provided.
Claims13
A gas/liquid separator element comprising:
- (a) first and second, opposite, end caps;
- (b) a media pack extending between the first and second end caps and defining an open central interior;
- (i) the media pack having a drain stage and a coalescing stage;
- (A) the media pack being configured for in-to-out flow with the drain stage surrounding the coalescing stage;
- and,
- (ii) the media pack having a cross-sectional periphery with a perimeter shape having a long cross-sectional axis, a short cross-sectional axis and an aspect ratio of at least 1.3;
- (c) one of the end caps including an outwardly directed spigot;
- (i) the spigot providing a support for a seal;
- and,
- (ii) the spigot defining an air flow aperture therethrough;
- and
- (d) a seal positioned on the spigot;
- (i) the seal defining a non-circular perimeter with a long axis, a short axis and an aspect ratio of at least 1.3.
