    • A snow filter for an airplane cabin air supply system is provided with a coned inlet screen which allows some air to pass through and some snow to be retained. The coned configuration diverts much of the air and snow toward a downstream conical retaining and collecting screen positioned toward the outlet of the snow filter. Snow is retained and collected at this point while air is able to pass through the screen. Downstream of the coned inlet screen and upstream of the conical retaining and collecting screen is an open air flow mid-portion that enables tortuous flow of air as the snow is directed toward the conical retaining and collecting screen in an annular collection volume. The outlet of the snow filter is provided with a contact sleeve that allows the snow filter to be fittingly received by a surrounding corresponding air duct. Thus a snow filter is provided that effectively separates snow from a flow of air while maintaining a clog-free path.
    • 用于飞机机舱供气系统的雪过滤器设置有锥形入口屏幕,其允许一些空气通过并且保留一些积雪。 锥形配置将大部分空气和雪转向朝向雪过滤器出口定位的下游锥形保持和收集屏。 此时,空气能够通过屏幕,保留并收集雪。 锥形入口屏幕和锥形保持和收集屏幕的上游的下游是敞开的气流中间部分,当空气以环形收集体积朝向圆锥形保持和收集筛网方向时,空气能够曲折地流动。 雪过滤器的出口设置有接触套筒,其允许雪过滤器被周围的相应的空气管道适合地接收。 因此,提供了一种有效地将雪与空气流隔开同时保持无阻塞路径的积雪过滤器。
