 Filter Sizing

When sizing the filter, you must take into consideration both the initial pressure drop (Δp) of the complete filter assembly (filter housing plus the filter element), as well as the fluid velocity through the filter. In return lines, it is recommended that the velocity be in the range of 5 - 13.5 ft. /sec. (1.5 - 4 m/sec.). The chart below outlines the optimal fluid velocity by connection size.
