Abstract: Various example embodiments relate to an automatic drain system for use with a fluid water separator. The automatic drain system includes a liquid-in-fuel sensor. The liquid in-fuel sensor is configured to detect a liquid level in a water sump. The solenoid has an open state and a closed state. A control unit is configured to activate the solenoid in response to a signal from the liquid-in-fuel sensor. Activation of the solenoid causes the solenoid to go from the closed state to the open state. The automatic drain system is placed in a condition for allowing fluid flow through the automatic drain system from the water sump.

Abstract: A filter that is retained in a shell housing by the use of a snap connection. The filter includes an endplate having snap features that interact with a groove in an inner portion of the shell housing. The groove may extend 360 degrees around an inner circumference of the shell housing. Accordingly, when the shell is unthreaded from the head for service (e.g., during a filter replacement service), the shell only needs to be displaced the length of the inner radial seal interface between the shell and the head, not the entire length of the filter media thereby minimizing the stroke length needed to service the filter assembly.

Abstract: A filter precleaner for precleaning an unfiltered gaseous mixture. A coalescing filter includes a filter media for filtering a gas, a nozzle assembly for precleaning an unfiltered gaseous mixture, and a lower endplate. The nozzle assembly includes a first nozzle plate positioned upstream of the filter media. The lower endplate is positioned at a lower end of the filter media beneath the first nozzle plate. The lower endplate allows liquid to drain through the lower endplate. The unfiltered gaseous mixture impacts the lower endplate such that liquid from the unfiltered gaseous mixture flows through the lower endplate and gas from the unfiltered gaseous mixture flows through the filter media.

Abstract translation: 通过使用卡扣连接件保持在外壳中的过滤器。 过滤器包括具有卡扣特征的端板，其与壳体壳体的内部部分中的凹槽相互作用。 槽可围绕壳壳体的内圆周延伸360度。 因此，当壳体从头部开启时（例如，在过滤器更换服务期间），壳体仅需要移位壳体和头部之间的内径向密封界面的长度，而不是整个长度 过滤介质，从而最小化维修过滤器组件所需的行程长度。
