Patent attributes
A filter assembly comprising a housing, a filter, a heater, hose fittings, a heat bridge, and insulators. The housing defines interior and exterior regions communicating through apertures. The filter separate the housing into a region upstream of the filter comprising an aperture, and a region downstream of the filter comprising an aperture. The heater extends into the interior region. The hose fittings are each coincident with an aperture and are formed of a material having a high thermal conductivity. The heat bridge is formed of a material having a high thermal conductivity and thermally connects the heater to the hose fittings. The insulators each are formed of a material having a low thermal conductivity, and each at least partially cover a hose fitting.
