Abstract
A fluid reservoir includes a reservoir body forming a reservoir volume and a header opening. A header seals the header opening and includes at least a heater disposed within the reservoir volume and a fluid draw conduit. A bag filter is connected to the header such that it completely encloses the heater and the fluid draw conduit such that, when fluid is drawn from the reservoir volume through the sump location, the fluid is filtered by the bag filter.
