Abstract

The present disclosure relates to an air processing assembly (204,312,318) for a vehicle (100,102), including a filter element comprising a PTFE based oleophobic membrane (306). The present disclosurealso relates to a corresponding method for drying compressed air.

Description

technical field [0001] The present disclosure relates to an air treatment assembly for a vehicle comprising a filter element comprising a PTFE-based oleophobic membrane. The present disclosure also relates to a corresponding method for drying compressed air. Background technique [0002] Trucks, buses, and related heavy vehicles often employ air brake systems in which compressed air from an air compressor or storage container is applied and released from brake chambers associated with the wheels. Air is typically supplied to an air dryer, then to an air tank, and then to an air brake. Air dryers are needed to remove water from the air brake lines and thereby prevent the problem of brake lines freezing in winter and other damage caused by water in the lines. [0003] In common implementations, air dryers typically use a desiccant to absorb water. While a desiccant works well at first, it loses its absorbency over time and becomes less effective. In addition, some oil is p...
