  • Patent number: 4941900
    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.

  • Patent number: 4247311
    Abstract: Apparatus particularly applicable to the drying of gases is provided for downflow or upflow adsorption of one or more first gases from a mixture thereof with a second gas to reduce the concentration of first gas in the mixture to below a permissible maximum concentration, having at least two sorbent beds, of which one is on adsorption while the other is being regenerated, and pneumatically operated valves for flow control of gas through the beds for adsorption and for regeneration. An overriding control such as a timer or a microprocessor programmed to control the regeneration time and purge flow fixes the cycling time, and switches the adsorbent beds at the end of each cycle period.
