Some settling may take place in funnel 30. The means 24 comprises a deflector member 55 having helically curved flutes 62 and a shield member 56. The inlet 18 is provided with a one-way ball valve 25. The filter element 40 (preferably containing resin impregnated cellulose) is mounted on outlet conduit 21 having two inlet openings 50 (only one shown) at its upper end, and is clamped between cap 39 and spring 43. The apparatus is mounted by brackets 16. The apparatus may comprise two bodies mounted in series, the filter element of the first body being coarser than the filter element of the second body, or in parallel, in which case each body may be used independently. The body portion 11 may have a sight glass for noting the level of separated denser fluid therein. The apparatus may be provided with means for sensing the level of separated denser fluid in portion 11, the sensing means when a desired level is reached, actuating a control device to open the valve at the bottom of portion 11 and to operate a pump for discharging the denser fluid.
