Drain Vessels & Float Drains FD130 Float Drain automatically removes liquids from the filter Drain Vessels are used to manually drain liquids from filters under negative pressure The FD130 automatic float drain is used in positive pressure systems to remove large quantities of liquid. The drain is added to the drain port of a filter housing fitted with a coalescing filter element. The liquid drains from the housing into the automatic float drain and collects in the bottom. As the level of the liquid rises, the float will open a valve, and the liquid drains out. The FD130 automatic float drain is suitable for use in systems with a positive pressure between 1 bar and 15 bar. For applications under a negative pressure, drain vessels can be used to collect large quantities of liquid. Valves installed at each end of the drain vessel will allow liquid to be isolated from the system and drained.
