摘要：A liquid filter construction comprising a filter housing is disclosed. The filter housing contains a filter element for filtration of liquids using a urea aqueous solution. A compressible element is positioned within the filter housing, the compressible element comprising an enclosure containing a gas-filled volume. This compressible element compresses in response to the generation of pressure from freezing of liquid within the filtration housing. The compression of the compressible element thereby avoids damage to the filter element, the filter housing, and adjacent equipment.
