Abstract
An air filtering device and related method for the removal of liquids and particulate matter from an air stream such as may be used in an aircraft environmental control system. The invention is comprised of an inertial separator and a combination coalescer and HEPA-rated filter preferably all located in the same housing. Air entering the housing flows into an inertial separator which removes most of the entrained liquid from the air. Substantially all of the remaining liquid is eliminated by the coalescing element with the coalescer functioning at least in part as an evaporator due to the low saturation level of the air flowing from the inertial separator. Biological and other particulate removal is accomplished by the subsequent passing of the air through the HEPA-rated filter medium.
