Freeze resistant water filter |
摘要 |
A freeze resistant filter cartridge assembly and methods for fabrication include a filter cartridge including a filter housing and a filter media and having at least one component selected from a list of components consisting of: the filter housing being formed of an increased elasticity polyolefin polymer having elongation and glass transition properties that allow for stretching of the housing during a freezing event rather than rupturing; a sleeve having a volume of air entrapped therein within and being disposed in the interior of the filter cartridge; and the filter housing formed of a conventional polyolefin having a wall thickness great enough to resist freeze induced expansion stresses. A disassemble cartridge filter includes a filter cap, a filter housing and a filter element. The filter cap and filter housing are rotatably attached wherein cap and housing engagement members prevent rotatable disengagement of the filer cap and filter housing. |
