ABSTRACT:
Fluid decontamination device includes a base having a fluid passage in it. An observation window is provided in the base for allowing a user to observe a fluid in the fluid passage. A differential pressure indicator, such as a vacuum indicator, is operatively connected to the fluid passage for indicating the relative pressure in the fluid. An indicator light which turns on when the differential pressure in the fluid passage is less than a predetermined differential pressure may be provided on the differential pressure indicator. A filter may be fluidly connected with the fluid passage for filtering out one or more contaminants present in the fluid.
